1. A Radio Frequency (RF) payment device comprising:

  • a RF transponder configured to receive a device authentication code from an RFID Reader communicatively coupled to a network;

    a unique device encryption key corresponding to a device identification code associated with the RF payment device;

    a biometric sensor configured to detect a biometric sample to create biometric sample data,wherein the biometric sensor is configured to detect an inauthentic biometric sample based on biometric scan characteristics, andwherein the biometric sensor is operable as a switch to place the RF transponder in more than one mode; and

    a device authentication circuit configured to use the unique device encryption key to encrypt the device authentication code and a device account code associated with the RF payment device to create an encrypted device authentication code and an encrypted device account code;

    wherein the RF transponder is configured to transmit at least one of the encrypted device authentication code and the encrypted device account code to the RFID Reader; and

    wherein the RF transponder is configured to be operable in the more than one mode including a selectivity mode and an inclusivity mode, wherein the selectivity mode includes enabling purchase of an item using a selected account number and the inclusivity mode includes the RF transponder in an operational mode permitting the RF transponder to be responsive to interrogation.
