RFID parking card melted ?

I was recently issued a parking pass that I assume contains an RFID chip. While I was getting organised in my car before entering the parking lot, I had the pass resting on the wireless charging pad in my Tesla Model Y. After that, the pass stopped working. It appears to have not only de-synchronised but also developed what looks like a small burn hole or damaged spot on both sides. Is it possible that the wireless charging pad interfered with or damaged the RFID chip? I’m being accused of using a ‘tool’ to damage the pass by the parking lot administrator.

Yup sounds like you cooked it, rfid cards contain a thin coil of wire acting as an antenna & induction coil, when waved at a card reader the induction coil in the card receives just enough power wirelessly to transmit it’s authentication/code. Same tech as a wireless charger just at a much smaller scale, so resting the card on the wireless charger probably over energized the coil and fried the card’s internals

Appreciate the insight. Thanks.

Plastic actually melted or being overdramatic? My garage opener remote that I left on the charging pad needed to be re-learned once. Thankfully you can turn the charging pads off as of a few months ago.

Quick question...where in the menus is the control to shut off the charging pads? I'm curious, because I looked for it in my 2019, but was unable to find it. For the record, I know the 2019's don't have an OEM wireless pads, but many (like myself) have upgraded to the 2021+ center console, and I wish they'd push that option down to all models, and let it work for the USB slots under the phone resting area in the pre-2021 consoles. Edit - spelling

I place my credit card inside my phone case and the whole thing on the charger. My credit card with a chip never developed any issues. Im still able to use it. The card is closer to the charger than my phone, so i don't know why. Phone charges fine too.

Most contactless cards use NFC at 13Mhz not RFID at 125khz which is what’s very similar to Qi charging operating range

Very welcome, sorry to hear it though

Why were you charging the RFID tag? Anything with metal coils or even Metal body will absorb induction energy and definitely get hot
