I am looking to duplicate RFID's for my building mates and friends in other buildings, we don't want to have to pay these exorbitant prices we are charged to get duplicates, if a new friend moves in. I am a complete newb to this industry, but, I have done some research and found myself here.
I would love the satisfaction of building my own device, but, due to the learning curve, I am a bit stumped on a couple of things.
Being in the same building, I understand the tags standard will be the same, but the other buildings, the standard most likely are going to be different, I have called around and I am told that I can't just have one device that can read / write all cards / FOBs. Now these are condo cards, I am not looking to do High- level security clearance badges lol. They are only for condos.
1.So my question is, can I purchase an arduino, since it can read the code with a shield and be able to read any card and then duplicate it ?
2.if so can someone help point me in the right direction for what I what controller would be best to help my with my problem.
3, I have also found a supplier for fobs, would it be safe to say I should get 125mhz and 13.25mhz.
Thank you in advance to anybody who can assist us on this problem!
