Hi everyone,


I'm working with a arduino NFC shield, with a NXP RC522 chip. With my program, I'm getting this timming:


Discover tag: 25ms

Write mem sector: 10ms

Halt tag: 25ms


The question: Can I bring this values down with another NXP IC? Or this values are a technology limitation?


If I can do it faster, which IC must I use?
