Most RFID-blocking wallets won’t stop AirTags from working. That’s because RFID and Bluetooth—what AirTags use—run on totally different frequencies. If you’ve slipped an AirTag into your mate’s bag or stashed one in your wallet for peace of mind, an RFID layer won’t muffle its voice. But of course, there’s always nuance, and some wallets might still impact tracking slightly depending on how they’re built.
Let’s break it down and see how these tech layers dance around each other.
What’s the difference between RFID and AirTag tech?
RFID (Radio Frequency Identification) is used for things like PayWave, access cards, and travel cards like Opal or Myki. These use high-frequency radio waves—usually around 13.56 MHz.
Apple AirTags, however, rely on Bluetooth Low Energy (BLE) to communicate their location to nearby Apple devices. BLE operates at a much higher frequency—2.4 GHz. That’s nearly 200x higher than RFID.
So, while RFID-blocking wallets are designed to block low-frequency signals to prevent tap-and-go theft, they’re simply not built to stop Bluetooth. The shielding in these wallets—usually a mesh of metals like aluminium or stainless steel—won’t interfere much, if at all, with the higher frequencies BLE uses.
Do RFID-blocking materials affect AirTag signal strength?
Not meaningfully.
The average RFID wallet blocks lower frequencies efficiently but allows high-frequency signals (like Bluetooth) to pass through. That means:
- Tracking still works even if your AirTag is tucked inside the wallet.
- Precision Finding still functions when you’re using the Find My app nearby.
- The AirTag will still ping Apple’s Find My network through nearby iPhones and devices.
The only exception might be if you’re using a wallet with a very thick metal case, or multiple layers of shielding. Some minimalist aluminium wallets, for example, have been known to partially block or muffle signal strength—not because they’re RFID blockers per se, but because they’re acting more like a Faraday cage.
Can someone hide an AirTag in an RFID wallet?
Here’s where it gets interesting—and a bit uncomfortable.
If someone wanted to slip an AirTag into a wallet as a tracker, an RFID-blocking layer won’t block it. That means wallets aren’t a safe zone from unwanted tracking.
That’s why Apple built in anti-stalking alerts. If an AirTag is travelling with someone who doesn’t own it, their iPhone (or Android, via an app) will eventually ping them with a warning. Still, it might take hours.
So, even though you might think your RFID wallet is “secure,” it’s not an AirTag blocker by any stretch.
Is there any way to fully block an AirTag signal?
Yes, but it’s not practical for everyday use.
You’d need to fully enclose the AirTag in a Faraday cage—a sealed box made of conductive metal mesh that blocks all electromagnetic signals. While it would prevent Bluetooth and even GPS signals, it would also turn your wallet into a bulky tin can. Not exactly pocket-friendly.
There are products online that claim to “block tracking,” but most either don’t work or are wildly inconvenient. Plus, blocking your own AirTag defeats the point of owning one for things like lost wallets, keys, or bags.
Are AirTags still useful inside RFID-blocking wallets?
Absolutely.
Plenty of people slide an AirTag into a slot inside their wallet to track it in case it’s lost or stolen. And because the signal still works, it’s one of the most practical and low-cost solutions for keeping tabs on something you carry daily.
If you’ve ever left your wallet at the pub or dropped it under your car seat (guilty), having that AirTag chirp or pop up on your phone feels like magic.
TL;DR – Quick Summary
- RFID-blocking wallets only block low-frequency RFID, not Bluetooth.
- AirTags use Bluetooth, so they work fine inside most RFID wallets.
- Signal interference is minimal, unless the wallet has heavy metal casing.
- RFID wallets won’t stop someone tracking you with an AirTag.
- AirTags are still a great option for wallet tracking.
FAQs
Q: Can I stop someone from tracking me by putting their AirTag in my wallet?
No. RFID protection won’t help. Your best defence is your phone’s AirTag alerts.
Q: Will my AirTag work if it’s buried inside a thick metal wallet?
Maybe not well. Some metal wallets may partially block signals. Test it.
Q: Is it safe to rely on an AirTag to track my lost wallet?
Yes, it’s one of the easiest, cheapest tracking methods available today.
Even after years of writing about tech and security, I’m still impressed at how clever a little coin-sized tracker can be. And while an airtag wallet won’t give you James Bond levels of protection, it’s a handy combo that works for most Aussies who want a bit of peace of mind.

Funny how we try to block one signal—and end up letting another ride straight through.
