arduino rfid rc522 problems
Recently, we were required to obtain a TWIC card by the contractor and plant I work for, under the auspices that it would be the only way we would be allowed to work on the dock area if we got any work out there. But after researching the RFID chip, I was alarmed to discover my card not only has a magnetic strip, but a chip as well.
Explain that TSA qualifies your TWIC as eligible and give them the # on the back of your card on the lower left. The # is also embossed on the front of your TWIC. Check your boarding pass and verify the pre-check symbol is there. If a chip is applied on a metallic surface and does not contain a protective layer, the metal reduces the radio frequency signals and the chip does not respond. The solution is to use transponders with special protection from ferromagnetic materials known as on-metal or anti-metal protection. Maybe you can help me figure this out. The RC522 works fine for a while, so should be no wiring problems, but after a few minutes it just starts either. sending an identical gliched readout from any RFID card. stops reading or sending RFID data completely. I have been unable to write to any RFIDs. I have tried 4 completely different types/brands of T5577 RFID’s including keychain and card style. Reading and all other functionality works great. I have re-flashed firmware to..
TWIC® card reader technology allows biometric matching using a contactless reader and determines whether a card has been revoked or reported lost or stolen. Many other types of readers can obtain and/or exchange information with a TWIC® card.
Symptom: Reader does not read the card; reader does not read the card properly or produces inconsistent data. Potential causes and basic corrective actions are listed in Sections 2.1 to 2.3 below. The Secure Technology Alliance Access Control Council has assembled and documented reported usage difficulties and symptoms of Transportation Worker Identification Credential (TWIC®) card and contactless reader failures with physical access control systems (PACS) from field installations.This issue is due to incorrect wiring or loose contacts to RFID sensor. You need to solder contact to get results. Also, choose appropriate PINS for your Arduino board.
