New Handheld RFID Readers Locate Tags Within Centimeters

This month, RFID reader technology company AsReader, Inc. released a new handheld reader with a 10-meter (33-foot) read range, which is available in two different models, ASR250G and ASR251G. Firmware from RFLocus enables users to not only interrogate an ultrahigh-frequency (UHF) RFID tag, but also identify in 3D where that tag is located in relation to the reader, within a matter of centimeters. The ASR250G is designed to be small and low in cost, the company reports. The handheld employs Apple iPhone- or Android-based devices, connected to the reader, to enable operation with an app.
