Description

Barcode Reader Having Forgery Recognition Function

The present invention relates to a bar code reader for recognizing a bar code of a product, and more particularly, to a bar code reader having a counterfeit detection function that helps the naked eye to determine whether a forgery of a bill paid for a product is purchased.

In large product discount stores and department stores, the product information is sent to the central processing unit or the computing terminal through a barcode reader in consideration of product information and convenience of product inventory management.

The above method is particularly advantageous in a store where various products are displayed because the product manager does not need to remember the detailed information (for example, price) of each product.

On the other hand, large product discount stores or department stores where barcode readers are commonly used have a large number of customers and various types of products being traded, so payment methods for purchasing products are also cash (especially bills), checks, and securities. (Ie gift certificates), cards, etc. are very diverse.

Among these payment methods, cards and checks receive a signature or contact information on a purchase receipt of a product at the time of a transaction, so that the identification of unauthorized users and the arrest of illegal users are relatively easy.

However, payment methods commonly used for commodity transactions, such as bills and gift certificates, do not undergo a separate verification process at the time of transaction, so identification and arrest of fraudulent users (especially counterfeiting and counterfeit gift certificate users) are relatively difficult.

In view of this, counterfeit detectors that can often discriminate against counterfeits in banks or pawn shops are equipped with counterfeit detectors. It uses a large scanner and a large lamp to increase the space, which not only takes up a lot of installation space but also high production costs.

Therefore, it is practically difficult to use the conventional counterfeit detector in a large product discount store or a department store.

In addition, the fluorescent material used in various bills vary in the wavelength range of the light to emit light, but the conventional counterfeit discriminator uses an ultraviolet lamp of an arbitrary wavelength band so that the fluorescent material does not emit or emit light in a specific currency. Many of them could not perform gastric discrimination function due to their low brightness.

The present invention was developed in view of the above, and its object is to provide a barcode reader with a counterfeit detection function that helps a product seller easily and conveniently identify counterfeit and counterfeit vouchers in a large product discount store or department store.

According to a first embodiment of the present invention for achieving the above object, in a bar code reader having a bar code scanner for recognizing a bar code displayed on a product and a communication port for transmitting an identification code recognized through the bar code scanner to an external terminal , Bar code reader having a counterfeit identification function is characterized in that it further comprises an ultraviolet lamp for emitting a colored fluorescent material on the bill.

Preferably, one or more light emitting lamps are further provided to facilitate barcode recognition through the barcode scanner, and the ultraviolet lamps may be arranged in parallel with the light emitting lamps.

In addition, the ultraviolet lamp preferably has a wavelength of 375 ~ 380 nm.

On the other hand, in the second embodiment and the third embodiment, the ultraviolet lamp preferably has a wavelength of 375 to 380 nm.

The barcode reader of the present invention has a low-capacity UV lamp with a specific wavelength that responds to a special fluorescent material used in a bill or gift certificate, so that a product seller can easily check whether the bill or gift certificate is counterfeit while reading the product information. have.

In addition, the barcode reader of the present invention has a communication port, such as a USB port, so that it is easy to connect with other terminals, and since a current can be supplied through the communication port, a separate power supply is not required, so sellers at the merchandise store It can be miniaturized for easy use.

Hereinafter, a preferred embodiment of the present invention will be described in detail based on the accompanying drawings.

1 is a cross-sectional view showing the main configuration of a barcode reader according to a first embodiment of the present invention, Figure 2 is a bar code reader showing the arrangement of the ultraviolet lamp and the light emitting lamp installed in the scan window of the barcode reader shown in FIG. Front view.

As shown in FIG. 1, the barcode reader 100 according to the present invention includes a body 10, a scanner 20, a light emitting lamp 30, an ultraviolet lamp 40, and a first communication port 50. Is done.

The body 10 is a member forming an external shape of the barcode reader 100, and has a size that is easy to be grasped and used by the user as a whole, and through at least a portion of the barcode or banknote of the object through the scanner 20 on the front side and scans It has a scan window 12 that can. Preferably, the front or head portion of the body 10 is formed to be wide and long so that a wide scan window 12 can be formed, and the middle or the remaining portion of the body 10 is chopped so that the user can easily hold it by hand. It is good to be. In addition, a predetermined storage space is formed inside the body 10 to allow electronic components including the scanner 20 to be installed, and the shape of the object obtained through the scan window 12 (that is, light emission of a barcode or a banknote). The mirror 14 reflecting the color and the light emitting form of the banknote to the scanner 20 and the circuit board 16 in which the electronic components are embedded are installed. In addition, a switch 18 for operating electronic components of the scanner 20 or the circuit board 16 is installed on the outer surface of the body 10.

The scanner 20 collects the shape of the object obtained through the scan window 12 of the body 10, codes it, and transmits the encoded shape to the circuit board 16 or an external terminal (not shown). In the present embodiment, in consideration of the size and manufacturing cost of the barcode reader 100, a general barcode scanner capable of only recognizing barcodes may be used as the scanner 20.

The light emitting lamp 30 serves as an illumination means for emitting light of visible or infrared wavelengths, and serves to irradiate sufficient light to the surface of the object so that the shape of the object can be clearly and clearly input through the scanner 20. Since the light emitting lamp 30 of the present embodiment is configured to illuminate a barcode made only of black and white, it is preferable that the light emitting lamp 30 is made of a relatively small lamp and arranged at regular intervals in the scan window 12 as shown in FIG.

The ultraviolet lamp 40 is a means for discriminating whether the banknote is forged, and is installed in the scan window 12 similarly to the light emitting lamp 30. In general, the fluorescent material used for banknotes do not emit well by the general ultraviolet lamp light, so in the present design, a small ultraviolet lamp having a wavelength of 375 to 380 nm is installed in the scan window 12 at regular intervals.

Fluorescent materials used for various bills are various in their wavelength, and thus also have various wavelength bands of light emitted. However, the conventional gastric obfuscation machine using an ultraviolet lamp of an arbitrary wavelength band has a lot of inability to perform the gastric obstruction discrimination function because the fluorescent material does not emit light or the luminous intensity is weak in a specific currency. In addition, in the case of using an ultraviolet lamp having a wide wavelength band in order to apply the distinction function to any bill, there is a disadvantage in that the power consumption is large, the power consumption is large, and it is easily deteriorated. Since a large number of lamps of various wavelength bands must be used, power consumption is high and product cost increases.

In order to solve this problem, the present invention empirically grasps the wavelength band emitted by the fluorescent material for the Korean, American, Japanese, and Chinese banknotes, and uses a UV lamp limited to the emission wavelength band (375 to 380 nm). It can increase the reliability of discrimination, reduce the power consumption, and simplify and reduce the product structure.

Table 1 is a table showing the degree of emission of the fluorescent material of the banknote in each wavelength band.

Korea United States of America Japan China 350-370 nm Weak emission Normal emission Normal emission Weak emission 375 ~ 380nm Normal emission Normal emission Normal emission Normal emission 380 ~ 400nm Normal emission Weak emission Weak emission Normal emission 400-410 nm Weak emission No flash Weak emission Normal emission 415 ~ 450nm Weak emission No flash Weak emission Weak emission 455 ~ 465 nm No flash No flash No flash No flash

The experiment was conducted for all kinds of bills of each country, the results of the bill type was the same for the bills of the same country. In each experiment, the degree of luminescence was measured using an illuminometer.

According to the applicant's dozens of experiments, when irradiated with an ultraviolet lamp having a wavelength of 375 to 380 nm, all the fluorescent materials used in various bills in each country were effectively emitted. Therefore, according to the present invention, even if a large-capacity ultraviolet lamp generally used for counterfeit discriminator is not used, it is possible to easily determine whether a forgery of a banknote is used, and it is not necessary to use a plurality of ultraviolet lamps of various wavelength bands. For reference, the present applicant used 'AL-UV151N-375' product manufactured by Eastern Tech Co., Ltd. as an ultraviolet lamp 40. However, the ultraviolet lamp 40 is not limited to the above products, any ultraviolet lamp having a wavelength of 375 ~ 380 nm is possible.

On the other hand, when the power consumption of the ultraviolet lamp 40 is large, the electrical drive stability of the external terminal connected to the scanner 20 or the barcode reader 100 is reduced, so that the ultraviolet lamp of relatively small power consumption (for example, 20 kW, 5 P) is preferably used.

The first communication port 50 is configured to transmit information obtained through the scanner 20 to the outside, and is electrically connected to the circuit board 16. The first communication port 50 according to the present embodiment takes the form of a USB port, and serves as an excuse for supplying power of an external terminal to the barcode reader 100.

The operation relationship of the barcode reader 100 according to the first embodiment configured as described above is briefly described as follows.

First, an object to be recognized, for example, a barcode or banknote of a product, is placed in front of the scanning window 12 of the barcode reader 100, and the switch 18 is pressed to scan the scanner 20, the light emitting lamp 30, and the ultraviolet lamp 40. It operates all the electronic components of the barcode reader 100, including. Then, the scanner 20 reads the surface of the object and transmits it to an external terminal (not shown) through the first communication port 50.

In such a situation, if the surface of the object is a bar code displayed on the product, the external terminal outputs the product information corresponding to the read bar code through display means provided on the external terminal, and at the same time, a logical operation (for example, Price calculation), and if the surface of the object is a bill, no logical operation is performed.

However, when the surface of the object is a bill, the fluorescent material used for the bill is emitted by the ultraviolet lamp 40, so that the user can easily check whether the bill is counterfeit.

Next, another embodiment of the present invention will be described. 3 is a cross-sectional view showing the main configuration of a barcode reader according to a second embodiment of the present invention. Figure 4 is a schematic diagram showing the main configuration of the bar code reader shown in Figure 3, Figure 5 is a flow chart showing the detection of forgery of the bar code reader shown in Figure 3, Figure 6 according to a third embodiment of the present invention It is a schematic diagram which shows the main structure of a barcode reader apparatus. For reference, the same components as those in the first embodiment use the same reference numerals, and detailed descriptions of these components are omitted.

First, a second embodiment of the present invention will be described. As shown in FIG. 3, the barcode reader 100 according to the second embodiment further includes a microcomputer 60 and display means 70 in the barcode reader of the first embodiment, and the scanner 20 recognizes the barcode reader 100. It is characterized by analyzing one image information by itself and outputting the result directly. The components further provided in the second embodiment will be described.

The microcomputer 60 is installed on the circuit board 16 and electrically connected to the scanner 20, and includes a storage unit 62, a search unit 64, and a central processing unit 66 as shown in FIG. 4. do.

The storage unit 62 stores various barcodes and commodity information corresponding to the various barcodes (for example, product names, product prices, etc.), and emits light colors or light emitting forms of various bills or securities (appeared during ultraviolet irradiation) and Corresponding banknote information (for example, banknotes or securities) is stored. For reference, since the position and shape of the fluorescent material is colored for each banknote is different, it is possible to determine the type of banknotes or securities through the light emission form.

The search unit 64 is connected to the storage unit 62 and the central processing unit 66, and the product corresponding to the light emitting color or light emitting form of the barcode or banknote that most closely matches the image information input through the central processing unit 66. The information or bill information is transmitted to the central processing unit 66. At this time, the search unit 64 transmits a separate error signal to the central processing unit 66 when there is no search information (referring to various kinds of information stored in the storage unit 62) matching the image information within the error range.

The central processing unit 66 is connected to the storage unit 62 and the retrieval unit 64, respectively, and temporarily stores image information recognized through the scanner 20 and simultaneously transmits the image information to the retrieval unit 64, and temporarily stores the image information. And shape information stored in the storage unit 62 (various barcodes and information on light emission colors or light emission forms of banknotes or gift certificates (indicated during ultraviolet irradiation)).

On the other hand, the display means 70 is electrically connected to the microcomputer 60 configured as described above, and serves as an output for outputting the value processed by the central processing unit 66 of the microcomputer 60 through sound or image. Preferably, the display means 70 is an image display means such as an LCD.

Next, the operation relationship of the second embodiment made in this way will be explained based on FIGS. 4 and 5.

When the user scans a specific portion (barcode or surface of the bill) of the object with the barcode reader 100 for identification of the object (for example, a product having a barcode or a banknote or gift certificate colored with fluorescent material) (S 10). In addition, the scanner 20 recognizes and codes the shape of the object or the light emission color and the light emission form emitted by the ultraviolet lamp (S 20), and transmits it to the microcomputer 60.

The microcomputer 60 determines whether the recognized shape is a barcode (S30), and if the barcode is a bar code, searches the storage unit 62 to output corresponding product information, and other logical operations (for example, calculating a product price). (S40).

When the microcomputer 60 searches that the barcode is not a barcode, the microcomputer 60 searches the shape information most similar to the image information in the storage 62 and separately searches for information (gift certificate information or bill information) corresponding to the formation information. (S 30). Then, the microcomputer 60 compares the image information with the shape information of the storage unit 62 (S40), and if the deviation of the comparison value is within the preset error range in the microcomputer 60, the two pieces of information are determined to coincide with each other. Otherwise, it is determined to be inconsistent (S50).

If it is determined in step S 50 that the two pieces of information are identical, a value corresponding to the formation information stored in the storage unit 62 is output (S 60). If it is determined that they do not match, a warning or an error is displayed.

On the other hand, the present invention stores the light emission color and the light emission form of the banknote or gift certificate appearing when irradiated with ultraviolet rays in the storage unit 62, and the central processing unit 66 compares the shape information of the object based on this, even if the counterfeit bill or Even if a fluorescent material is used in a counterfeit voucher, the counterfeit can be easily determined.

Therefore, according to the present invention, it is possible to easily determine whether a counterfeit bill or a counterfeit voucher is used as well as information of a product through a bar code for identifying a product in a large product discount store or a department store. It is easy to solve the counterfeit problem that occurs.

The third embodiment relates to a barcode reader device 1000 in which the barcode reader 100 and the terminal 200 of the first embodiment are detachably coupled, and in terms of the overall device structure, are similar to the second embodiment. Description is omitted.

That is, the barcode reader device 1000 of the third embodiment is the second device except that the microcomputer 60 and the display means 70 included in the barcode reader 100 of the second embodiment are built in the terminal 200. Similar to the barcode reader of the embodiment.

However, the difference from the bar code reader device 100 of the third embodiment and the bar code reader of the second embodiment is that the electronic components (for example, the microcomputer 60 and the display means 70) occupy a relatively large space. By installing in the external terminal 200, the size of the barcode reader device 100 can be further miniaturized, and through this, the high performance scanner 20 can be installed without any space restrictions.
