I was inspired by @cexshun’s project using the iClass reader in his home and decided to check eBay costs. I found a RK40 reader/keypad that was open box never installed for $20 and bought it. It’s an outdated model but I don’t think that will matter to me. Looking at the spec sheet here it says it’s compatible with iso 14443a cards. I should be good with my NExT in that case right? Did I make a mistake? I did check the compatibility matrix and don’t see it listed yet.
