RFID 13.56 Mhz Chips: RFID Integrated Circuits operate at 13.56 MHz

From Industrial News Room, NY ... 3-wire microcontroller interface, Model EM4094 provides up to 200 mW of OOK or ASK modulation output from 5 V supply and is suited for handheld RFID readers. ...

RFID standards work is being performed at the International Standards Organization (ISO). ISO/IEC 18000 Information Technology AIDC Techniques provides standards for RFID Item Management - Air Interface. The scope of this Standard is to provide Physical Layer, Collision management System and Protocol Values for RFID Systems for Item Identification operating at 13.56 MHz in accordance with the requirements of ISO 18000-1. The ISO-18000-3 standard defines a standard set of communication guidelines for 13.56 MHz RFID tags. The standard improves the ability of reading multiple vendor tags with a single standards-compliant RFID reader. The standard does not address the data structure of RFID tags. Vendor ISO 18000 tags may have variable amounts of memory and be used in different applications. The standard address the RFID communications, but not the content (data) of the communication.
