SKIDATA - NFC and HF Tag Testing

CASE STUDY

Ensuring customer satisfaction through approved suppliers

Supplier Approval

Although the number of different chips used for HF RFID is limited, different suppliers deliver tags with different performance characteristics. Even if different manufacturers get the same chip, then there is still a variation due to the used tag materials and production processes. NFC Xplorer provides various test modes for the evaluation of potential suppliers and their products. The performance on resonance frequency, load modulation, and H-field characteristics need to be fulfilled.

Importance of Load Modulation

Various different readers are used for HF RFID applications. Those readers range from desk readers, gate readers but also module readers. While the ISO criteria for load modulation with 10 mV for ISO/IEC 15693 is rather low, it is beneficial for the use experience to have tags with significant stronger load modulation. Therefor the load modulation as function of the magnetic field (H-field) at 13.56 MHz is used as criteria to define the requirements for supplied tags, as well as defining it as design parameter for all types of readers that are developed.
