Re:Spurred by Amazon, Supermarkets Try Swapping Cashiers for Cameras on Monday July 08, 2019 @07:27AM (#20381784)

Checkout machines will have RFID readers. When you place your bag inside RFID reader, all tags will be read.

UHF based RFID readers are better since they have more than 1 meter of read range.

I believe instead of using sensors and camera with computer vision, what if someone uses RFID systems for self checkout.

Implementing RFID would be cost effective as compared to implementing Amazon Go based approach. Where you need to install sensors and camera installed!

RFID tags are the major cost, which can be solved with bulk purchases.

Decathlon has already deployed RFID based self checkout system!

I don't want to build a NFC based readers. Although, I have watched tutorials on NFC reader with Arduino (RC 522 module). It's not that complicated.

My ideal scenario where reader will be implemented is retail stores (Once prototype is working as expected).

from the ask-hn dept.

I am a software developer with no experience in electronics.Access to electronics workshop won't be an issue since my uncle has business in electronics. Also, I don't mind reading and researching on RFID.At the moment my reader should be able to read multiple tags with less than 1 meter of distance.I would like to know what challenges one can face while building their own RFID reader.Thanks in...
