NFC CREW

The NFC CREW read/write system for functional test is a hardware/software package that interfaces an RFID module and allows it to be managed simply and effectively from both NI TestStand and NI LabVIEW during the validation or test sequence.

NFC CREW is based on an RFIDClick module featuring an on-board ST CR95HF transceiver for near field communication (NFC) at 13.56 MHz.

The supported communication protocols are:

• ISO/IEC 15693
• ISO/IEC 14443-A
• ISO/IEC 14443-B
• ISO/IEC 18092

The user communication interface can be either RS232 serial or USB.

The communication library, developed in LabVIEW, provides RS232 serial control of the RFID module based on the ISO/IEC 15693 protocol and supports the following commands:

• Set Password
• Read EEPROM tag
• Write EEPROM tag

Writing is performed using NDEF tags with any payload (type and length according to the standard). Where required, specific bytes can also be written in raw format through the RAW Data interface.

The RF carrier state can be controlled programmatically, switching it ON or OFF as needed.

Finally, the CC bits can be programmed, so that a new tag can be prepared for use.

The library integrates fully into NI TestStand, speeding up its deployment for functional test.

The IPSES NFC Test Bench control panel implements every function of the NFC library. Where required, the panel allows the operator to work on tags directly and very quickly, or it can be customised to suit specific needs. Alternatively, the library can be embedded in other systems (LabVIEW, TestStand and so on), guaranteeing maximum flexibility of use in any situation.
