2.5 Card testing
2.5.1 Introduction
If you suspect, that the card to be tested is a multiprotocol card, it is always
good to present the card in two different ways to the reader:

Move the card slowly towards the reader.

Drop the card quickly and directly onto the top of the reader.
The reader will give two beeps if it supports two protocols.
The reader should be ready to read (the red LED is solid on) before the card is
presented. Presenting a multiprotocol card that support for example two
protocols will result two beeps.
If for example the card support both HID iClass and HID Prox. Dropping the card
quickly will result in two beeps and reading of both ID codes. Presenting the
card slowly will return only the HID Prox ID code (as it has a better reading
range).
