10 PCS GEN1 13.56 MHz UID Writable Rewritable Clone IC Smart Key Fobs, Compatible with MIFARE Classic 1K, RFID Blank Tag for Access Control

Works with Aqara smart locks

was at a great value, great quality product performance is good. This product is true and does meet the criteria as it stated.

Exactly what I was looking for! They were the exact specs as advertised, and unlocked! I was able to write to them with out issue.

I’m able to write my hotel keys to these so I don’t need to keep the hotel key cards in my pocket

They sort of work, sort of don’t. You have to sometimes do it twice. They also fall apart easily. Other than that, they’ve done the job (just not well). Each one lasts about 5 months for me in my pocket

In the listing these tags says "UID Rewritable" complete lie and waste of time. Why misrepresent your product? I purchased these specifically because I needed mifare 1k classic fobs that I can change the UID aka V2 "magic" RFID tags. These tags are writable but BLOCK 0 (ZERO) is LOCKED

These work like a charm and they're built like a tank. I was able re-program them with a Flipper.

Great quality, I use them everyday

Funcionaron perfecto!!
