RFID interference is a common, but not the only way your access card can get demagnetized. If you recall some basic middle school physics, every magnet has a magnetic field created by electrons moving between the two poles. When one magnet comes close to another, it affects the other card’s magnetic field. I think the two cards are probably interfering with each other. I don't think HF RFID has a channel access protocol (like UHF does in Slotted ALOHA), so both cards respond at the same time and the reader can't understand either.When these cards are near each other, does this hinder them from being able to swipe into your office, or use contactless payment? The short answer is — yes! This can actually happen, and in practice often does. RFID interference occurs when external sources disrupt the radio waves used by RFID systems for communication between tags and readers. This disruption can distort or block the signals, preventing the reader from accurately identifying and tracking tagged items.
Discover the most common RFID problems and learn proven solutions to optimize your system’s performance. This comprehensive guide covers troubleshooting tips for signal interference, power supply, tag placement, and more.
I have a stack of 4 cards, 3 of which have RFID. When I tap this stack of cards on readers, they interfere with each other, and nothing gets read. What can I do to ensure that the card closest to the reader gets read? I keep my RFID cards separate by leading one in the catscard slot of my wallet and the other in the cash fold. As it is neither are strong enough to work from the inside of the wallet, so that might be enough separation depending on how thick your wallet is.
I just got a second RFID keycard for work, and I've run into an issue where if I put them into a card wallet (one piece, no fold) they interfere with eachother and just don't work reliably. When I try to put a RFID blocker in between them, all that happens is .
In any RFID deployment, we recommend a six-step approach to minimise the risk of interference: Audit the frequency spectrums used by devices within the same environment. Clarify with suppliers the frequencies, protocols and standards used by the equipment.
Radio frequency interference from nearby electronic devices or metal objects can disrupt communication between the RFID card and the reader. Try using the card and reader in a different location to see if the problem persists. RFID interference is a common, but not the only way your access card can get demagnetized.
