(adsbygoogle = window.adsbygoogle || []).push({}); Hello guys,
My University (here in BA, Argentina) has eliminated the manual code for checking assistance and installed the RFID Student ID Card, the problem is now nobody can call the assistance for you because when you ask for another card because you "lost" yours, the old one gets disabled.
So my question is, as I have never tried or even check intensively about this subject, is if I can clone my RFID Card and some of my friends so that when one can not assist his assistance can be check with the cloned card by another friend?

I hope I have been clear enough. I apologize in advance for any technical mistake. It would be great if any of you could assist me with this matter.

Would appreciate if the solution is cheap or can be done with accesible materials.

Thanks in advance.

You would need the proper software and hardware to do it. The software can be free or paid but the hardware is not free and most likely not cheap

You can use a phone that has NFC.

Ewwww RFID....

I actually built an RFID reader as a project. You can find these chips easily on ebay for like £5, you'd need an arduino and some programming skills, I think there's a way to make it write too im not too sure. Note some RFID readers have different frequencies, in my case it would only work with some of my cards (my debit card, oystercard/bus pass) but not with my college ID. So you may have to find out what frequency your card is. The setup should be the same though.

An arduino is kinda like a mini computer (like a raspberry pi) except that it has no OS, has a tiny amount of memory, but can be programmed (and is wayyy faster than using a Pi) to do pretty much anything with the right setup.

The whole thing cost me under £20, but again this was a basic RFID reader (not cloner, but same hardware might be able to clone, haven't really researched into it)

it might take a few weeks or months to learn everything, but it is totally worth it.

Also that instructables site is really worth it, if you're into building mini projects, that site is really useful.

I agree that Arduino is the way to go. There are free-to-use RFID libraries out there, even with examples of how to read and write to RFID cards. The Arduino shouldn't cost more than $25, the RFID reader/writer $15 I guess.
