125KHZ EM4100 RFID Soft Paper Sticker Dia 30mm Read Only (Pack of 10)

I purchased these to create an easy way to unlock a DoorBird door system. Worked flawlessly. I am still trying to figure out where I can stick it on an iPhone case where it doesn’t get interference from the phone. But spots exist, you just have to be careful about where you stick it. Bottom line, works very well for my purposes.

They do not work. Don’t buy

I bought this since all of the RFID tags that Hornady includes with its RAPiD series of safes are fairly bulky. This worked perfectly. Nice and thin so I just stuck it to the back of my phone. Recognized immediately by my safe, and adding it was the same process as adding any Hornady RFID key. Works fine through my phone case as well.

Had to scan the reader and pull the logs to determine what the numbers was, As they were not listed. Otherwise these work perfectly, I’ve placed it inside my phone case. No more remembering my keys every time I go to the bathroom, and I always take my phone.

Not much to say other than these are 125KHZ RFID read-only stickers. Great for using with a compatible RFID reader if you want to make puzzles. Stick them inside a 3d-printed object or thin wood to hide them, or stick them on the bottom of an everyday household item to turn it into a key to unlock a hidden door.

Works perfectly with a Hornady rfid safe.

I received them the next day , but most of them were bent , they all had data written on them , was unable to copy over the data or use ... seems as someone's return was ship to me .. order at your own risk .

Didn't test them all but 2 of 5 didn't work.

buen producto

går ej och använda trots rätt scanner går ej och kopiera vanliga Rfdi

Works when placed inside a phone case, tapped against an access control keypad.
