Meikuler 13.56MHz MIFARE Classic 1K, RFID Smart Card / M1 Card, ISO14443A Printable Blank RFID PVC Cards for Access Control, Hotel Key cads, etc (200)

Terrible print quality opposed to cards from reputable brand. [EDIT: Nevermind. One of my students messed up the settings on our badge printer. These work great.]

So far so good. We use it at our Church.

Reads well and was even able to print on the cards

I have two different sets of RFID cards and the other ones I have will write just perfectly. These ones won't

These cards work with my 13.56 Mhz RC522 RFID card reader for raspberry pi / arduino. There are many types of RFID cards so make sure you know what type of cards your system uses before purchase.

I use RFID cards for my automated train project. These cards work very well for that purpose as they do not have to be in contract with the reader. Beware some similar cards sold by other vendors have to be right next to the reader to work.

Arrived quickly and was exactly what we needed. Love the blank space to print passwords for WIFI

We added some keypad locks to our facility that use the MIFARE 13.56 MHz frequency. We purchased these cards to replace our 125 kHz cards so we could use one card for both systems. These cards do work, but only when exposed. Most of our users put the card in their wallet and hold their wallet near the access control reader. These cards do not work when placed in a typical wallet like our 125 kHz cards do. This is a showstopper for us. I'm not sure if this a limitation of the frequency or if the card is cheaply made. We are returning these cards and are looking for an M1 card that will work when placed in a wallet.
