BlueBerry HS UHF is a mobile mini RFID reader, keychain shape, capable of reading UHF tags and transmitting the acquired data to any device equipped with a Bluetooth® radio interface.

The maximum reading distance is 30 cm for UHF far field tags and 2 cm for near field UHF tags.
The use of the RFID reader is easy and intuitive thanks to the presence of a single button, to activate the reading of the UHF tags (1), and an LED and a multi-tone beeper, to alert the operator of the reading.

BlueBerry HS UHF integrates Bluetooth® radio technology, in particular it uses HID and SPP profiles.

With the HID profile the data transmission takes place in keyboard emulation mode, mono-directional channel (2). This profile supports all major mobile devices, including those equipped with iOS and Android operating system, as well as the main desktop or portable devices, including those with Windows, Linux and Mac OS operating systems. Thanks to this profile, any application or program that accepts identification data entered from the keyboard can receive the same data transmitted by the BlueBerry HS UHF (3).

With the SPP profile, data transmission takes place in virtual serial mode, a two-way channel. A simple serial communication protocol, present on all TERTIUM Technology products, allows to manage all the RFID reader functions, in particular the ID scan and the reading / writing of the UHF tag memory. With this profile it is possible, during development, to integrate RFID technology in any application or program for mobile or desktop or portable devices (4).

BlueBerry HS UHF is battery powered. Charging carries out via a micro USB connector.

Through the same USB port it is possible to connect the BlueBerry HS HF to a PC, so that it can also be used as a normal RFID desktop reader. Data transmission on the USB interface takes place in virtual serial mode, a bidirectional channel (managed through the same serial communication protocol as the Bluetooth® SPP interface).
