White papers
These articles provide more theoretical background and insights on topics in NFC communication and sensor technology. Typically they are based on my peer-reviewed articles in scientific publications.
Impedance in the EMVCo Test Environment Measurement and Calculation
Contactless Payment incorporates the Proximity Card specification for the physical-layer of the air interface. The physics is based on the coupling of resonant loop antenna circuits in...
RF System calculations for ISO/IEC14443 Proximity transponder
We derive and use analytic formulas to calculate some aspects of the RF behaviour of Proximity Card transponders at the contactless air interface. The aspects we consider cover the minimum...
