2128L UHF RFID Reader with High Gain Linear Antenna and ePop-Loq®

  • Made for iPod iPhone iPad

    Maximum Performance

    The 2128L UHF RFID Reader builds upon the 2128 UHF Reader by including a larger, fixed High Gain Linear antenna for up to 15m (49ft) of read range. The patented TSL® ePop-Loq® connector allows data and charge connections to be passed from the reader to an attached device, such as a smartphone or handheld terminal.  The unique ePop-Loq® system is also designed to safely separate when the reader is subject to large impacts, such as when dropped.

    Enhanced Modes of Operation

    The 2128L UHF RFID Reader can provide in-reader tag de-duplication for more than 50,000 unique tags from more than 1 million tag reads. In addition the Reader can store on-board (using the embedded micro SD card) more than 250 million* unique tags with date and time stamping for a truly powerful batch collection mode of operation.

    Sophisticated user feedback provides the most configurable, in-depth and capable ‘search and find’ features currently available.

    Single Point Charge Solution

    The 2128L Docking Station allows charging of both the 2128L UHF RFID Reader and a smartphone or handheld terminal attached via an ePop-Loq® mount. This unique design can accommodate a wide range of devices from many handheld and smartphone manufacturers. The 2128L Docking Station Kit is supplied separately and includes the docking station, power supply unit and a USB data cable.

    Powerful and Comprehensive Software Development Tools

    The 2128L UHF Reader boasts unrivalled levels of RFID read/write performance, particularly in applications where longer read range is required or where there is a very dense collection of tags.
    Applications developed for the 1128, 2128, 2128P 1153, 1166 or 2166 UHF RFID Readers can easily be configured to work with the 2128L, as all of these readers share TSL’s unique ‘ASCII 2 Protocol’. This sophisticated, parameterised set of commands carry out multiple actions locally within the reader. This approach enables multiple tag operations to be executed using simple pre-configured ASCII 2 commands which not only speeds integration of the reader into applications but also makes application development easier.

    Flexible Bluetooth® Connectivity

    The 2128L supports both Bluetooth® Classic as well as Bluetooth® Low Energy (BLE). The reader can be operated in Serial Port Profile (SPP) or Human Interface Device mode (HID), as well as supporting iApp2 for Apple iOS devices. The reader also supports an automatic re-connect mode for both Android and Apple devices.

    Ultra Secure Data Gathering Option

    As the ePop-Loq® system provides a wired connection between the host device and RFID Reader, sensitive data can be given that extra level of security by avoiding the use of wireless data transfer. The 2128L supports batch data collection and is equipped with a Micro SD socket and a real time clock. Up to 250 million* transponder EPCs can be stored on the embedded 16GB* NAND storage card. This provides the ability to collect and log data even if USB or Bluetooth® communication channels are not available. Docking the 2128L then enables this data to be synchronised with a PC.
