MSR90 USB Swipe Magnetic Credit Card Reader 3 Tracks Mini Smart Card Reader MSR605 MSR606 Deftun

Worked fine. but before you buy understand that it can only read cards not write. thats why i returned.

Simple and effective, works as a USB keyboard device. Reliably reads cards and can be used in many applications.

Kind of a bummer that the programming software only works on Windows, but it can read cards even on macOS.

Worked fine for the first three months. Light now blinks green continuously and will not read any cards. Wasn't expecting this to last a lifetime, but was expecting it to last far longer than 3 months.

Works as intended. Small, lightweight design. Effortless plug and play via USB. We use these for software access on office computers, everybody has a mag strip card that is their “password”. Didn’t come with any method of mounting. Purchased double sided tape and worked well.

Simple to use and decent value. Does exactly what I need it to.

This is a simple product that does exactly what is claimed. The info on the magstripe of a swiped card is entered into your computer exactly as though you typed it on the keyboard. It works out of the box with nothing special needed. If you were entering information based on this, you would need to make sure the computer is ready to accept the numbers before you swipe the card... such as positioning the cursor in the credit card number box on the screen.By default it sends all of the track data at once with a prefix and suffix for each so a program could tell which one is which. There's a small piece of windows-based configuration software that's optionally used to config which tracks to send and whether or not to use a prefix/suffix.Note that you would not be able to get it to send just the card number, or just the name on the card unless the card is encoded that way. Typically a card will have multiple bits of information on the same track. Most payment systems that allow one to use a card reader would know to expect the info in this format (which is a standard) and is not exactly as though you'd type it by hand reading from the front of the card. All that to say, you're not going to be able to use this to swipe your card and fill out the checkout form on a typical online store. But if you're using it for a payment system for a business and the payment system works with a card reader, then this will very likely "just work" with no special settings or anything.I gave it a slightly lower rating for accuracy in that if you are not careful about how you swipe, you'll only get track 1 data even if track 3 is present. But if you're careful to insert the card flat when swiping it gets it just fine. It either works or doesn't and doesn't send partial tracks or incorrect info.

I will begin as upfront as possible: I don't know the technical difference between two-track and three-track magnetic strips for cards. I do know, however, that this reader did not work with the EBT cards we issue at our office. The older card reader we have is listed as a two-track card reader, so I assume then that our cards are two-track and aren't compatible with three-track reader. Please correct me if I'm mistaken.Now, that's not to say the reader doesn't function at all. It will read the numbers; however, it also inserted a semicolon before the number and followed the number with a couple other random symbols and other numbers. When input into Notepad, this is no big deal and can be manually corrected. When input into the site we use to issue cards, however, it doesn't process correctly, presumably due to those extra symbols and the character limit of the field.So, while this product may technically work, it is unfortunately not as simple as "plug-and-play" for all parties. I can't detract from the score entirely due to my own ignorance in the matter, so I'll go with 3 stars.
