Hi Leszek Piotrowski,
It depends on your application. If you only use it for reading cards, RC663 is recommended, but if you use it for P2P as well, PN5180 is recommended.
For local tech support, please kindly contact your local DFAE for help. You may refer to Distributor Network|NXP for details.
Hope that helps,
Have a great day,
Kan
