IQBOX R835
HF | NFC Embedded Reader
IQBOX HF | NFC Embedded Reader R835 is a series of high-performance, low-cost readers designed for integration into vending machines, healthcare systems, medical devices, and electric vehicle charging stations.
Thanks to a state-of-the-art microcontroller and the latest HF transceiver technology, the R835 allows reading and writing almost all 13.56 MHz transponders. The series offers five different configurations compatible with major RFID standards: ISO 14443A/B (T=CL), ISO 15693, ISO 18092 / ECMA-340 (NFC), and ISO 18000-3.
The HF | NFC R835 reader features a built-in antenna, with read distances up to 8 cm depending on the transponder type.
The TTL and RS485 serial interfaces allow quick integration with existing electronics or the development of new high-performance identification applications. USB and USB HID versions with PC/SC interface are also available, ideal for payment solutions.
The IQBOX hardware comes with a complete SDK for developing applications based on controllers, Linux, or Windows. In addition to documentation, command protocols, and source code, the SDK includes a Windows demo software with full functionality for all supported HF RFID standards.
