30pcs M1 Classic 1K 13.56MHZ RFID Smart Cards ISO14443A M1 Cards Printable for Access Control, Hotel Key cads, etc

EDIT: After running into the SAME issue with another brand of cards (for a different system) I discovered my HR dept was punching some of the lanyard holes right through the tag antenna! So, I humbly return to BEG forgiveness and update my 2 stars to 5 stars, as that's CLEARLY not a fault of the manufacturer. Time for some retraining on our end. ORIGINAL REVIEW (no longer valid) 4 out of 19 didn't read. We'll definitely be looking for a different brand.

Excelente

These are not rewritable but they do work. Bought them for skylanders and wasn't happy that they say rewritable but their not.

I bought these to be able to give electronic keys to people that I could disable at any time with my Aqara U100 lock. They work perfect! Not much else to say besides that this is a much cheaper option than the official Aqara nfc tag and these fit in a wallet.

Works as expected. Easy to set up. Works with Sifley Locks and 1/10 of their price.

NOT EXPENSIVE AND WORK GREAT

these cards are NOT 0 block rewritable

Could not get them to link with my phone or iPad.

Las compré por que la ocupo para la cerradura de un hotel , dude mucho al comprarlas pero realmente funcionan , solo debes de investigar bien si es la frecuencia correcta y qué tipo de tarjeta será , me fincionaron bien y también las mandé a personalizar , se ven gastadas pero es por el uso , es normal pero la verdad funcionan de maravilla

Non of them work ..
