two printer clients touching the same card request causes client to crash

Two cards are printed (one from each printer). The MIFARE_NUMBER for the slower client will not be returned to the Card API. As both card are identical (apart from the MIFARE_ID), there is a chance the card sent to the user will not match the card record stored in the Card API.
