1. A telecommunications device, comprising:

  • a DTMF generator;

    a microprocessor coupled to said DTMF generator; and

    a radio frequency transceiver coupled to said microprocessor;

    wherein said radio frequency transceiver is configured to;

    detect existence of a radio frequency tag;

    receive from said radio frequency tag a radio frequency signal comprising tag data associated with said radio frequency tag, said tag data being associated with an item with which the radio frequency tag is associated; and

    provide said tag data to the microprocessor;

    wherein said microprocessor is configured to do the following substantially at the time the radio frequency signal is received;

    receive said tag data from the radio frequency transceiver;

    associate said tag data with an associated DTMF sequence; and

    cause the DTMF generator to provide said associated DTMF sequence as output; and

    wherein said radio frequency tag is attached to a business card on which information for an entity is displayed and wherein said tag data is associated with a telephone number for said entity, whereby said microprocessor causes the DTMF generator to dial said telephone number for said entity in response to receiving said tag data.
