Simple to Use
Worked perfectly for the school fundraiser craft fair. Easy to use and stayed connected even in a location with poor network connection.

Works well, plug-& play
These were basically plug-in play. We use them just for gift card transactions. The reader works well.

Does what it says it does. High Quality.
This works find for what it is. It does not do any encryption so most payment gateways do not allow its use. If need a usb card reader this one will do that trick.

Not compatible with MAC OS
Is not compatible with MAC OS. Is not a simple plug & Play. No state-side support for product. Will be returning. It is also not the MSR605 version that was sent.

Good card reader
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.

Just plug it in
Very easy to use. It does not come with any standstill adhesive. If you want it to be in a stationary spot, I highly recommend getting something to keep it in one spot.

Works like a charm
This works perfectly. Not much to it. I had no problems using it as a swiper for meetings for an organization where I am the secretary and have to swipe member cards. Hasn’t failed me yet.

works as advertised
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.

For the price, this card reader has proven to be a great value. It works well and reads most cards easily. I use it when collecting card holder information at my martial arts school. I appreciate the compact size that takes up minimal space on my front desk. I plugged this into a windows laptop and it was a simple plug-and-play. No settings or setup to go through, worked right out of the box.

Did not work or go online. I just wanted to copy my building swiping card waste of money through it in the garbage and just bought another key the landlord which cost me $100 should’ve done it from the first place
