Review: one of the better card readers I have used - 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
Review: Works perfectly, good quality, could use a weight in the base - Bought because I was wanting to experiment with smartcards. It worked perfectly with several different card types and was trivial to install. I've used it with the PIVKey available here on desertcart as well as NXP JCOP cards without issue. I also have an SCR3310 and prefer the Omnikey over it as its much more sturdy. HID's products tend to be good quality in my experience, though expensive at times. I do recommend using the official drivers from HID as opposed to the stock Windows driver as they're much newer. The base was a bit tricky to put on at first as its not immediately obvious how it fits, but once attached is fine. One suggestion for HID would be to put a weight in the base. The reader grips cards pretty well when inserted and you can pick the reader up by the card...more weight would make one-hand removal of cards easier.
