2173 Bluetooth® Wearable LF/HF RFID Reader

  • The 2173 Bluetooth® LF/HF RFID Reader enables a Bluetooth® host device to read and write to a wide variety of Low Frequency and High Frequency RFID transponders. The optional 2D Imager version can also capture 1D and 2D barcodes.

    Scanned information can be ‘typed’ by the Reader into any application on the host device using the Bluetooth® HID keyboard mode. Alternatively, the Reader can be commanded from an app on the host device. As the 2173 Reader uses the existing TSL® ASCII 2 Protocol, developers can take advantage of the comprehensive, free SDKs provided by TSL® to develop in Xamarin, Java, Objective C or .NET.

    TSL® Reader Configuration

    The above Apps have been created by TSL® to demonstrate the performance, functionality and versatility of our Bluetooth® UHF RFID Readers. They also serve as demonstration of TSL’s powerful ASCII 2 Protocol. This sophisticated, parameterised protocol provides the developer with a powerful set of commands that carry out multiple actions locally within the reader. This approach enables multiple tag operations executed using simple pre-configured ASCII commands, which speeds up integration of the reader into applications. There are also an ever-increasing number of compatible Third-Party Apps available.
