Hi Philipp,
NXP contactless products are certified against several standards. For X ray it is defined in:
ISO/IEC 7810, Third edition 2003-11-01
AMENDMENT 1 2009-12-15
AMENDMENT 1: Criteria for cards containing integrated circuits
9.1 X-rays
The card shall continue to operate as intended after exposure of any card surface to medium-energy X-radiation as described in the test methods in ISO/IEC 10373-1, with energy in the range of 70 keV to 140 keV, of a cumulative dose of 0,1 Gy per year.
NOTE This corresponds to approximately twice the maximum acceptable dose to which humans may be exposed annually.
I take always NXP contactless cards in my hand luggage with me at my business trips. It is checked in X ray scanners at the airport and I never found defect cards after scanning. The dose from modern X ray scanners are very low and does not damage electronic equipment.
Could it possible that the card was damaged in a different situation?
