rfid rc522 not reading card
As on connecting the M522 module with arduino uno and running the "dumpinfo" sketch, it didn't scan the card or tag i.e. Shows nothing. I have checked all connections and also on checking the version of rfid reader, it shows it v2. This project uses an RFID reader with an Arduino to scan RFID cards, print their UIDs to the Serial Monitor and whether they are denied or granted access, and control LEDs to indicate access status. I added an LED . Some of the RC-522 RFID card reader modules that can be bought on ebay / aliexpress have a problem: they do not read all (types of) cards they should be able to read. In .When * you present a PICC (that is: a RFID Tag or Card) at reading distance of the MFRC522 Reader/PCD, the serial output * will show the ID/UID, type and any data blocks it can read. .
Incorrect data format: If the data format on the tag does not match the requirements of the RFID reader, it will also cause read or write errors. Solution: Check and replace RFID tags: Check the status of RFID tags regularly to .To see the output: use Tools, Serial Monitor of the IDE (hit Ctrl+Shft+M). When * you present a PICC (that is: a RFID Tag or Card) at reading distance of the MFRC522 Reader/PCD, the .

I was attempting to make an RFID system for a long time now, and I consistently ran into one problem: The reader would not ever read a card. I even tried the built-in self-test function and it . When * you present a PICC (that is: a RFID Tag or Card) at reading distance of the MFRC522 Reader/PCD, the serial output * will show the ID/UID, type and any data blocks it . When * you present a PICC (that is: a RFID Tag or Card) at reading distance of the MFRC522 Reader/PCD, the serial output * will show the ID/UID, type and any data blocks it .

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 . This project uses an RFID reader with an Arduino to scan RFID cards, print their UIDs to the Serial Monitor and whether they are denied or granted access, and control LEDs to indicate access status. I added an LED to the previous breadboard circuit:
When * you present a PICC (that is: a RFID Tag or Card) at reading distance of the MFRC522 Reader/PCD, the serial output * will show the ID/UID, type and any data blocks it can read. Note: you may see "Timeout in communication" messages * when removing the PICC from reading distance too early. you present a PICC (that is: a RFID Tag or Card) at reading distance of the MFRC522 Reader/PCD, the serial output; will show the ID/UID, type and any data blocks it can read. Note: you may see "Timeout in communication" messages; when removing the PICC from reading distance too early.Incorrect data format: If the data format on the tag does not match the requirements of the RFID reader, it will also cause read or write errors. Solution: Check and replace RFID tags: Check the status of RFID tags regularly to ensure that the tags are not damaged. When * you present a PICC (that is: a RFID Tag or Card) at reading distance of the MFRC522 Reader/PCD, the serial output * will show the ID/UID, type and any data blocks it can read. Note: you may see "Timeout in communication" messages * when removing the PICC from reading distance too early.

I thought I had a problem with my code, but then even after switching to Arduino Uno the card is not being read or detected, but the key fob is working fine. I am using the examples from the famous MFRC522 Library by GitHub Community available in the Arduino Library manager to do the tests.
I was attempting to make an RFID system for a long time now, and I consistently ran into one problem: The reader would not ever read a card. I even tried the built-in self-test function and it passed (See Attachments).
