Reliable CAC reader
Summary: Had an old SCR331, and decided it was time to upgrade since that one started working intermittently.Recommendation:Update your driver from the HID site (link below). YES, it will work with Windows 10 without _but_ the Windows driver is generic, and from 2006. HID has an updated driver from last year (2019). One odd behavior is that I have a Dell CAC keyboard too, and with my CAC in the HID Omnikey, sometimes it would not recognize the card; I would need to remove and reinsert the CAC. Maybe this driver update will help (has not done it in the past 24 hours).Pros:1) Same parent company that owns ActivClient (or more like HID acquired Omni).2) Good fit & finish. Vertical stand is a plus, and removable for alternate orientations.3) Drivers for Linux and Mac also available (did not test).4) A co-worker put double stick velcro on his CAC reader, and put it to the top/back of his monitor (which makes it easy to remember to pull your CAC when you leave the space).Cons: None.

5.0 out of 5 stars one of the better card readers I have used
Reviewed in the United States on September 2, 2022
Verified Purchase
I received this smart card reader earlier than expected, and when I went to use it the first time, I had no issues using it and setting it up. Well there really isnt much to do as far as setting up. Its pretty much a plug and play setup. There are options for downloading add on software that you can use to test your reader to make sure its working properly, but for the most part you just need to plug it in to your computer and start reading smart cards or writing data to cards. This reader/writer works with pretty much all JCOP cards and has alot of supporting information on their site. I would prefer to use this reader over its other version thats a little more portable but I dont think the other version is as accurate or reads as fast as the OMNIkey. I have been using this reader on a regular bases and it has been working perfectly with now issues. it evens displays information from cards that I didnt know it even could read. So I suggest investing in the reader if you are getting into carding or if you just want to see what these readers are all about, you can learn alot from just messing around with it and seeing what kind of information you can pull from different cards and chips

Got this to use with my mil ID card - it's sturdy and I didn't need to do a thing except plug it in. I'm sure it will last longer than my previous card reader. For reference, I'm running windows 10 on one PC and windows 11 on another and this worked right away on both.

3.0 out of 5 stars USB3 was a lie, no stand
Reviewed in the United States on October 3, 2023
Verified Purchase
I wanted to like this, especially spending my own money to stabilize a WFH connection environment, but I specifically searched for USB3, since so much of the peripheral device world has its head up its butt instead of modernizing to USB-C, it was the best I could hope for. Disappointed to receive a crappy USB2 device with no stand, this is going back and my time was wasted. Save yourself.
