NFC reader with raspberry pi?

Sun Jan 13, 2019 9:20 pm

I am want to create a card reader with NFC sticker using the raspberry pi and the PN532 reader. Would this be possible?
Also if someone has links to cheap NFC stickers and the reader, that would be greatly appreciated!

I think you will find many examples of people getting readers with the PN532 chipset working with the pi. ( PN532 is not the name of a reader but is the name of a chip that many NFC readers use. )

Your biggest choice is what kind of interface you will use. Will you buy a USB reader or an RS232 reader or one that uses SPI or I2C.

USB readers are very simple to connect and usually comes with 1m cable.
RS-232 readers must have power and must be correctly connected to the UART on the GPIO ports.
SPI/I2C readers can be found that can connect directly on the GPIO pinheader, but also similar to RS232 versions.

Do you think regular NFC stickers will work with it? I saw some on Alibaba :

I am going to be creating a NFC card reader that allows employees to clock in and out. I am going to have to make up each card with its own individual sticker.

How many employees do you have ?
Do you plan to put the stickers on existing ID badges ?

I have no experience with NFC tags of that specific chip, I use slightly more expensive cards, so its not completely clear for me if they are guaranteed to work.
