Given the rapid pace of technological progress, new fields of application for NFC technology are constantly emerging. In addition to the areas of payment transactions, identification/access control and ticketing, new applications are emerging in Industry 4.0 and the Internet of Things. Here, it is crucial that the transponders used are compatible with the corresponding readers.
The first step is to define suitable test cases that address the essential functions required for the application. These are worked out and programmed in cooperation with the relevant card and reader manufacturers. The capabilities or functions of the transponder tested by these must be implemented by the manufacturer. In order to be able to evaluate the performance, the time required by the transponder to process specified tasks is measured. To ensure that this time measurement is independent of the processor's internal clock rate, the reader's fixed transmission frequency of 13.56 MHz is used as the clock standard. A timer of the card is switched to the reader clock and measures a part of the program sequence.
With these standardized performance tests, it is possible on the one hand to check the actual functionality of the transponder and the reader. On the other hand, the performance of the transponder can be tested in conjunction with a reader and vice versa. This gives SMEs the opportunity to find out during the development phase how well their product will perform
in combination with an appropriate reader or transponder. with a corresponding reader or transponder. This can also save costs: For example, it eliminates the need for time-consuming compatibility tests at external test laboratories, which SMEs in particular cannot afford for every product change or technological development.
