rfid reader detects the card the other one doesn't 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. When an NFC tag is detected, the Android system will send an NFC intent to your app. You need to override the onNewIntent() method of your Activity to handle the NFC intent. Here is an example .

After a while I decided to reverse engineer the nfc reader so other people can still use amiibo on their original 3DS, 2DS and 3DS XL without buying the expensive nfc reader. I started by looking at existing documentation on the .
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.

The problem that surfaced is that some of the RC522 card readers won’t read some cards (Including the OV-chipkaart). That’s obviously a problem when the door won’t open or the machine won’t start, or your project using those card readers doesn’t work with all the cards it should be working with.Discover essential troubleshooting tips for the RFID reader and writer. This comprehensive guide covers common issues like data reading errors, distance problems, and interference, providing practical solutions to ensure your RFID systems operate smoothly.Step-1: Change the RST pin to 5 if you are using Arduino Uno or use RST pin 9 in Arduino Mega. the other pins remains the same. Step-2:Download AddicoreRFID library. 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. 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 .
