Product Line

Security Expert


Security Expert Smart Card Reader


Card readers work by modulating the electromagnetic wave in different ways to resolve between 1s and 0s. There are several different ways to bring card data across 125 kHz; ASK, FSK and PSK.

ASK : Amplitude Shift Keying
FSK : Frequency Shift Keying
PSK : Phase Shift Keying

Since the technology used is determined at the hardware level,  a reader would need to have the hardware to read a specific type.

Security Expert 125 kHz readers make use of FSK only, which means that e.g. Indala cards (125 kHz PSK technology) will not work with them.


Use FSK technology 125 kHz cards with Security Expert Smart Card Readers.
