Recently I lost my key card for my dorm building. The customer service is awful and they are in no hurry whatsoever to make me a new one. Not to mention it is going to cost me like 20 euros. Is there any way to dupe the card if I ever misplace it in the future? Maybe it's even possible to dupe it on my phone using NFC? The card itself is white on both sides with no barcodes or markings. I am not sure if the cards hold any information that could link it back to me or if it's all the same for everyone. It's a concern since the dorm housing rules state that card duping is a punishable offence.
