Often times an office finds the struggle of granting access to rooms without jeopardizing physical copies of keys. These struggles can be easily overcome with technologies such as facial recognition, finger print recognition, bar codes, radio frequency identification, and much more.

The PN532 is the most popular NFC chip, and is what is embedded in pretty much every phone or device that does NFC. It can pretty much do it all, such as read and write to tags and cards, communicate with phones (say for payment processing), and ‘act’ like a NFC tag. If you want to do any sort of embedded NFC work, this is the chip you’ll want to use!
