RFID keys feature 13.56MHz interface

In a move targeting the 2billion units/year automatic identification, access control and e-cash markets, Maxim Integrated Products has announced a new line of rgid keys and cards.
According to the mixed signal and analogue specialist, the new contactless MAX66000/020/040/100/120/140 devices are 'ideally positioned' to gain market share as they incorporate a 13.56MHz interface, which is becoming the global standard for such applications. Some countries have already begun deploying this rfid technology for passport and national id cards.
The rf devices are based on Maxim's 1-Wire secure authentication iCs, which are designed to protect intellectual property in embedded systems. They are packaged in a laminated plastic key fob or ISO thin card format and are available in either the ISO 14443B or ISO 15693 HF protocol. Each protocol offers three products: 64bit ROM ID only (MAX66000/MAX66100), ROM ID plus 1Kb eeprom (MAX66020/MAX66120), or ROM ID plus 1Kb eeprom and SHA-1 authentication (MAX66040/MAX66140).
The MAX66040 and MAX66140 employ the secure hash algorithm (SHA-1), a proven technology designed by the NSA for protecting a system's critical data without using encryption techniques or an untested, proprietary protocol. SHA-1 is a publicly available ISO standard designed to maintain the integrity of stored data so that one can verify the authenticity of any credential.
Maxim says the rf keys and cards are custom programmable and work with most 13.56MHz readers on the market.
