YIQing S9-BU-13-00 RFID NFC Reader Writer 13.56MHZ USB Contactless/Contact Smart Card Reader+2 Pcs 4442 Cards +2pcs MF1 Cards + Free sdk

As a first time user this was a bit difficult to understand how to use. I needed it to duplicate a FOB that my apartment complex issues to get around in common areas. It's a good tool to have if you need to write RFID cards. it was able to read and copy the card info over without issues.

I did buy this RFID reader more than a month ago, and I thought it was going to work like the other ones I have installed before, but it does not! you have to install the software, then you will spend a huge amount of time figuring out card types, ports, testing, changing bauds, loading keys, etc.the bad news, is i cant return it, because I did not try it before, now is too late

I had trouble getting this to work. The instructions were in a hard-to-understand rough English translation. I just ended up buying a cheap used Android phone to read/write NFCs.

this was so hard to figure out the cd was confusing & was translated by someone who has no right to speak English at all

I'm not an expert, needed it to experiment with for some hobby projects. Not the most user friendly, but I blame myself for not being more experienced. I bought some wristbands that were supposed to be compatible but they didn't work. Again, I blame myself, since the included cards work I assume it wasn't the device that was malfunctioning.

Performs as expected, and quickly as well. Setup is kind of a hassle because it's obvious that the programs that come with this were not well thought out. They work as intended though!

I had lots of trouble getting this to work and returned it. It is very complicated to setup and use. I would not recommend this.

The ease in which I was able to add the information to the cards in order to keep track of my employees hours
