SavaPage ships with a Network Card Reader Service to be deployed on a
Raspberry Pi®. The service is tested to work with the popular
ACR122U reader. The installation instructions can be found in:
Other ACS USB readers mentioned in the README should work as well.
Any deployed service must be entered as SavaPage Device. See Section 4.9.1, “Network Card Reader”. At each card swipe the UID of the card is read and send to the central SavaPage server, where it is handled in context of the device definition.
