GAO RFID has developed and released a multiple-input software for its series of Class II Bluetooth RFID Readers. The software is ready for use for PCs that have a Bluetooth adaptor or are otherwise Bluetooth enabled and runs on most Windows Operating systems including XP and Vista. In its current version the software allows for up to four Bluetooth reader inputs on a single PC or laptop computer.

The palm-sized RFID Reader is available in three frequencies: 125 kHz, 134 kHz and 13.56 MHz. The wireless Bluetooth based RFID devices are compatible with most types of RFID cards, have a data transmission range of over 10 meters and have a long battery life - continuously reads tags up to 7000 times per charge. These readers also work with WinCE 5.0 or Windows Mobile 5.0/6.0 based SmartPhones or PDAs; however the multi-input software for these devices is still under development.
