We are using the PN533 board for a Vietnamese ID card reading project. The integration has been successful.
Currently, I have two questions that need clarification:
- Is it possible to configure the Serial Number for the PN533 board?
- After removing the card, it takes about 2.5 seconds before the next card can be read. I would like to configure the system so that the card removal time is less than 0.5 seconds.
PN533 is a very old product. We don't recommended it for new design. I would suggest you to use the PN7462.

@jimmychan , We are using the PN7462 for our main products, however, the PN533 is an option for other products.
