## Description

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: Must have! - Have had this for YEARS and it still works. Has kept me from having to go back to work to check my email. Does what I need it to do without costing too much.
