1. Metallic materials are interfering with the operation of the RFID reader or RFID/NFC chip. If the RFID reader is attached to a metal housing or if it lies on a metallic base, the reading distance between the reader and a tag can be reduced due to electromagnetic .
A digital business card is a plastic card that contains a NFC chip in which the recipient writes his contact information with his phone, and when he meets a new friend or business partner. 1. Metallic materials are interfering with the operation of the RFID reader or RFID/NFC chip. If the RFID reader is attached to a metal housing or if it lies on a metallic base, the reading distance between the reader and a tag . An effective illustration is a stack of tagged playing cards, where HF has a 100% read rate, if you stacked 52 cards on top of one another, a UHF antenna could not read even one card when similarly stacked on top of one another.

I have tried the cards that came with the device, cards that I got from a previous RC522 that arrived broken, and cards I got from hotels. I have both the small round keychain cards and the white credit card sized ones, and neither will read. I recently bought a new original Proxmark3. I can read and write to hf and lf card, can see all of the information etc. Now to the part that doesn't work. I wanted to scan / read my entrance card, I use to get into office, but it doesn't seem to .Read the RFID card UID. Get the selection from user using pushbuttons. Restart the code for new cards. The problem is, It reads the card and gets the input from pushbuttons. But after the first loop, It doesn't detect other cards (or the same card again).
Are you sure that your RFID card is working ? Are you sure the card is of a type that the reader can read ? Fastest way to test both is often using a smartphone with NFC and an app like "NXP Taginfo".
When an RFID card is brought close to an RFID reader, the reader emits a radio frequency signal. The antenna in the RFID card receives these signals, inducing a current in the antenna. 1.
