Abstract

The invention relates to a device producing DTMF sequences, which device is provided with keys designed for the production via megaphone of DTMF sequences to be used for the dialing of phone numbers via a telephone device connected to the network ofthe telephony provider. By pressing the proper key, the user may be connected to the smart platform services and send its PIN thereto. DTMF sequences are renewable via DTMF tone exchanged with said platform. The device may be also used as an electronic prepaid calls electronic card characterised by renewable talking time units, as a quick dialing electronic card for preset phone numbers, as a televoting device characterised by reprogrammable voting dialing numbers, and as a client recognition/identification electronic card the platform dialing number and PIN of which are renewable after each transaction, for enhanced security.
