ACR1252U USB NFC Reader III

I purchased this to use in conjunction with a Yubikey 5 NFC for logging into Windows machines as an MFA token (using Authlite on the back end). Once I got it figured out it works perfectly ... but it doesn't work without swapping the drivers for the reader (read on for more).First you have to have Authlite installed on the machine with the NFC support option. When you connect this NFC reader Windows is going to detect it as a generic Microsoft smart card reader, with this driver installed the reader does not work properly. I found that I had to go to the manufacturers website and download the drivers for the reader (they are provided as a convenient MSI file as well for deployment). Once those drivers are installed I could get the reader to work with the Yubikey and it would fill in my MFA value. One thing to remember is the reader will beep twice in this usage ... once when the key is detected, then about a second later the yubikey value will be entered for you, then it beeps again to say its complete.Hopefully that helps someone else down the road. Now that I have that sorted out I'll be able to use the NFC readers in a factory setting to make things a little easier for my users.

As a Technical Professional, I perhaps have unrealistically high expectations for my electronic purchases. I always expect problems with drivers, firmware or software. HOWEVER - I was pleasantly surprised with this unit. I easily downloaded the driver from the manufacturer (Advanced Card Systems) website. I painlessly installed the Windows 10 driver and a couple of the ACS programs. The software and drivers worked immediately without any problems nor lost time on my part to make it all work. My compliments to ACS!I downloaded some 3rd-party software to test as well. NFC21 programs (free) immediately connected with the reader/writer without any issues. I was very impressed with the NFC21 software working so nicely for my testing of NFC NTag215 disks.Using the ACR1252U Reader/Writer has been great my NFC tag experiments and work. I now have to purchase an additional unit for an employee because I won't share my unit. I am using it daily and don't want the hassle of unplug/plug each time they need to use it. The price was good enough and it works so well for me so far that the labor costs I didn't spend on driver and software installation problems easily pays for a second device.

I’m using in conjunction w a cold wallet for crypto. Works great.

I bought this to use a Yubi Key with my desktop. Not working with that so I don’t know if does anything but beep. If it is working it was plug and play.

This seller asked for 50 bucks and it's fixed like a 13 dollar product.This is a lazy programmed product

I recently purchased a Yubikey 5 and keep it on my keychain. Rather than plugging it in directly which can be hard on the port and the key, (all of my keys together weigh a bit) I wanted to get an NFC reader, so I can just lay my keys on it and have access to all of it's features.Plugged it in, Win 10 picked it up as a CCID Smart Card Reader. Placed my yubikey on it, beeped once, and was detected. Pulled up gpg --card-status, detected my card and read back all of the keys I have stored on it. Literally could not have been easier.It's the right price and seems fairly well built, the beeping is a little annoying (but ). It can be a bit sensitive to the card moving, but seems reliable enough.

Doesn't work, just makes a beep sound nothing else.

Works well with Linux. Easy to read, write and erase NFC tags.
