Desktop Reader

The DR-E/U-USB®  UHF RFID Desktop Reader is an integrated Gen2 RFID reader and writer.  It was specially designed for desktop applications. With its small and elegant factor, it is simple yet flexible to use. Because of its efficient RFID module and low power consumption, it is only powered by a standard USB port. We named the models 


which is derived from the Greek word 'akis'  meaning "sharp point".

With its excellent, well focused read/write performance we are confident to answer many existing and upcoming desktop based RFID applications.  The ACACIA comes with many software programs and SDK.
