13.56 MHz RFID Key Fobs - 5-Pack Writable Smart Tags Compatible With MIFARE Classic 1K

About This Product

Tech-savvy folks and security enthusiasts, these RFID key fobs are seriously useful for access control systems! This 5-pack of 13.56 MHz tags is compatible with MIFARE Classic 1K systems, which are pretty common in building security, offices, and residential complexes. What's really cool is they're writable and rewritable, so you can program them with specific UID codes and even update them later if needed. The keychain design makes them easy to carry - you can attach them to your keys, backpack, or lanyard so they're always handy when you need to access secured areas. The cloning capability means you can duplicate existing access cards, which is super convenient if you want backups or need to provide access to multiple people. I've used these to create additional access fobs for my office building when we ran out of the official ones, and they work perfectly with our existing readers. The 13.56 MHz frequency is standard for most modern RFID systems, so compatibility is pretty broad. Having five in the pack is great because you can set up multiple users or keep spares for when ones get lost. The construction feels durable - they're not flimsy and should hold up to daily use in pockets or on keychains. If you're managing access control for a business, apartment building, or even just want to organize your own security system, these writable RFID fobs are an affordable and flexible solution. They're way cheaper than buying official replacements from security companies, and the rewritable feature gives you so much more flexibility. Definitely worth having on hand if you work with RFID access systems!
