Abstract

Described herein is a radio-frequency identification (RFID) credential configured to provide a plurality of message formats. The RFID credential includes a low-frequency proximity chip. The proximity chip includes a controller having a protocol sequencing module, an analog front end, a modes register, and a modulator. The protocol sequencing module is programmed to deliver messages associated with the plurality of message formats to the analog front end using the modes register and the modulator, the delivery of the messages occurring in a sequential manner based on the message format of the message. The modes register is configured to store a plurality of message formats, and one or more bits in each message format identify the message format type.
