ISO14443 device level compatibility with MIFARE

[meekeech]

I'm aware that there's a standard called ISO 14443 and an associated testing standard that is at a component level (ie PN7462 module).

My question is: if I'm designing a custom version of an existing evaluatoin board (ie PNEV7462C), do I need to test to the ISO standard mentioned for my new antenna size?

Is there a chance we won't successfully communicate with something like an Infineon tag or a MIFARE or something? 

Thank you,

MArko

Thank you for your interest in our products.

ISO14443 is a standard for a type of RFID tag, It isn't required to work with it but, most of the tags that are sold work under it.

This will depend entirely on the tag you will communicate to.

In order to design an antenna please take a look at our Antenna Design Guide.
