The RFID R831 Series OEM HF Stick Reader

Innovative and compact Design – Available in different 13.56 MHz Versions!

iDTRONICs RFID R831 Series OEM HF Stick Reader is now available in different versions that support a different range of RFID transponders. The different versions include a high-end as well as a multi-ISO variant. The high-end version supports almost all common transponders in the RFID HF range; including DESFire, NFC, and microprocessor solutions. The Multi-ISO variant is characterized by its price-optimized performance and is a NXP MIFARE CLASSIC variant to provide a cost-effective solution.

All versions are available as USB Virtual ComPort (VCP), as well as in a USB HID Keyboard Emulation (expect DESFire version) mode. According to customer requirements, the HID output of the reader may be adapted in advance to the requirements of any specific application. Thanks to its slim design, the RFID Reader may also be integrated into applications where space is limited. An integrated LED and a buzzer facilitate indicate status during use.

The RFID stick reader may be used for access control during production, or as an authentication aid in the healthcare sector.

Excellent technical specifications

The different versions are operated via the USB 5 Vdc power supply. USB drivers are supplied for Microsoft Windows, Linux, MAC OS, and Android systems.

Read & Write function for a wide range of transponders

  • DESFire: ISO 14443A/B and ISO 15693 and compatible
  • HF: ISO 14443A/B und ISO 15693 and compatible
  • MIFARE: ISO 14443A compatible

Software development kit & tool for Windows configuration

A user-friendly software development kit (SDK) and configuration tool for Windows operating systems is provided as well as an operating system-independent command protocol. Further adjustments to the firmware and hardware are possible on request and project basis.

Application example: Access control in production

Different employees are assigned within process steps in production. Each process step must be monitored and controlled by an assigned employee. The Reader is ideally suited for this area of application. The module can easily be embedded into existing devices and connected via USB 2.0 interface. The use of MIFARE DESFire cards facilitates identification and tracking. The card can be written with data and information about the person. The Reader can read this data using a unique UID and successfully assign it to the member or employee.

The data can be transferred in two different ways. The transfer of all access data can be done using the VCP mode via USB cable and special commands. The VCP mode offers complete read and write access for all supported transponders. In HID mode, user data from the supported transponders can be retrieved as keyboard emulation.

DESFire belongs to the MIFARE family and is a registered trademark of NXP Semiconductors.
