NCTU Research - RFID Tag Testing


NCTU research on RFID-based On-lens Sensor System relies on RFID Xplorer

With the aid of CISC RFID Xplorer calibration we were able to measure the chips turn-on power characteristics and export the data through CISC RFID Xplorer GUI interfaces accurately,” says Shun-Hsi Irving Hsu, Research scientist at NCTU .  “The new testing process is compatible with Gen2 RFID protocol extending the flexibility and reducing the self-developed firmware efforts.

Meticulous Testing of RAIN RFID tag in Healthcare Applications

Healthcare applications require meticulous tag testing procedures. In the current research, a specified verification process was established to measure the performance of the tag. The researchers used RFID Xplorer tag performance testing software to develop a cyclic redundancy check (CRC-16). In the verification process, they first needed the tag response to be acknowledged and then the read command was used as the command sequence to measure the turn-on power required for the tag.

Extensive Chip Design Verification

For this application, extensive chip design verification was performed by RFID Xplorer conformance testing suite for evaluation of the prototype On-lens sensor. It allows programming instructions to be sent to the RFID tags using standard RFID commands or user-defined commands, following the Gen2 RFID protocol definition. The overall testing covered tag access tests such as read/write memory test, timing measurement, response strength test over frequencies and power levels, and others.

NCTU achieved 50%
faster time-to-market

  • Saved up to half the current R&D time to develop customized needed for the application
  • Extensive chip design verification test shortened the chip selection process by 20%
  • Strengthened knowledge and understanding of the performance of the tag when interacting with the reader
  • Reduced the time-to-market of new products by 50% due to the set up of in-house testing capabilities
