I'm working on a check-in system for our reception using a Raspberry Pi, a RC522 reader and MIFARE RFID cards. Guests tap their card to check-in and the monitor displays their table number. I'll log their check-in time among other things. Is there a point to it? No, it's just to be fun and cool.

Just make sure you have a hard backup. You don't want to be troubleshooting tech on your wedding day.

Happy Wife = Happy Life.

Would have been better without the sexist cliche :)

If you're doing RFID cards I'd appeal to you to make them in the form of pin-badges that the guests can wear after 'check-in'.

I've been to many weddings over the past couple of decades and the one that was most successful in terms of breaking the ice between strangers had simple badges with ${NAME} and ${RELATIONSHIP TO COUPLE} on them. People felt very comfortable striking-up a conversation when they knew these two pieces of data, and there was less 'must remember the name' anxiety.
