One interesting piece of news which I saw in Using RFID:

Integrated Engineering has introduced a new contactless smart card reader. The SmartTRANS reader provides a transition path from existing proprietary legacy 125 kHz Prox technologies to open standards ISO14443 technologies. It combines ISO14443 technologies, such as MIFARE, DESFire and PIV, and 125 kHz Prox technologies in one reader, and provides flexible configurable output formats and output protocols. The SmartTRANS accepts a wide range power supply voltages from 4.5 to 16 Volts DC. The reader is intended to add value to an existing infrastructure rather than replace it.
