Our facility just got upgraded with new door readers that can use NFC through cards or phones to grant access. I'd like to also use cards or phones to provide authentication to our instrument use system. Could anyone direct me to information on how I would securely set this up? We were provided some NFC readers to test with. They are USB. When you plug them in and scan they emulate a keyboard and type a number. I could associate this number with users but this doesn't seem very secure. Shouldn't there be some key exchange during this process?
