13.56MHZ MIFARE Classic 1K Key Fob RFID Access Tag Black Metal (5)

I specifically bought these for the Aqara Smartlock u100, based on others mentioning these worked with their smart locks. I can confirm these do in fact work quite well.You can bind 2 of these per user, and if you have multiple smart locks like I do, you can bind the same tag(s) to each smart lock if you want. Or if you want to have one tag give access to one door and not the other, you can do that as well.

Funciona de maravilla para reemplazar las llaves plasticas que venian con mi chapa inteligente Tecnolite.Ya vienen programadas, asi que solamente tienes que darlas de alta en tu chapa como si fuera otra huella o pin.

Wanted a robust NFC tag. These worked great, paired them with an Aqara U100 lock like the other review mentioned.Nice and heavy duty, should last a long time.

Ottimo rapporto qualità prezzo

Sehr zuverlässig in der Funktion als auch in der Programmierung. Hat sofort Tadellos funktionierte und seither jeden Tag im voll zufrieden.Die Schrauben seitlich sollten aber auf jeden Fall angezogen werden.
