RFID for the widest range.

Projects General Guidance
1

Hey.

So i was looking around to make a new project but not a hard one but a rather simple one. Atleast i think that it might be simple but how it works by itself might be complicated.

In either case. I want to make an RFID reader/writer for any card that has RFID.
Why? For fun really.

But i am not 100% on what RFID readers/writers i should go for nor do i know if there is one that can
read and write on a wide range of radio frequencies rather than multiple once for diffrerent frequencies.

Any tips would be very nice.
Thanks and happy new year.

Search this Forum for RF stuff or Google on it. You will get plenty of answers. I don't play with those things, otherwise I would give You a real suggestion.
