Works with Square UP Credit Card Reader
579784
Well I bought this on based upon the reviews from other buyers of this product that claimed the splitter will allow one to use their credit card reader with their iPhone in an Otterbox Defender case. All I have to say is thank you, it works like a charm with my Square UP credit card reader that I bought while at Starbucks. On the plus side I get a spare pair of earbuds  just in case my original iPhone earbuds crap out for some reason.

So basically if you are wanting to use your Credit Card Reader with an iPhone in an Otterbox Defender case, then buy this and you won't regret it :-D

works like magic -- no more accidental scanning at the checkout line -- less worries of being "jacked" for my credit cards

it would appear that this reader is going to do that I needed to do by reading various size USB cards. Having multiple cameras in each one uses a different card you need a reader that can handle them all. This card reader appears to fit the bill.

works in my laptop integrated card reader, Dell Venue 8 Pro, and Canon Powershot A630. I saved the plastic packaging as it can be used as a ghetto case that fits in my camera case pocket ;)

A good choice for adding a multi card reader to a 5.25" slot on a PC case. I ordered one for use in my Phanteks Enthoo Luxe Full Tower Case so I would not have to use a portable reader using up a USB port. The fit was not perfect, I had to squeeze the tray while attaching the screws to the card reader. Not a big deal, just not a super tight fit. The front plate is plastic but matches the look of the aluminum on my Phanteks case. There is a slight "grain" pattern that is horizontal, so if you have a case that has a pattern running vertically and you are super picky, then this may be of concern.

Works fine, and I like the bin feature.  it seems to take more and run longer than the specifications suggested.  Only one problem--the credit card slot sends out credit cards in long, easily readable strips.

The smallest multi-card reader I've encountered yet. Construction feels solid even though it's light as a feather. It will fit very well in any laptop or netbook bag. It even has an extension USB cord for desktops which came in handy for me. It allows me to access multiple cards at the same time and at lighting fast speeds. Overall, I'm very happy with this buy.

This compact card reader works very well for me...I use an iMac, which has an SD reader (but not a micro SD reader) on the back of the unit, but it is annoying to get behind the computer every time I download from an SD card. I have mounted this to my desk for easy access and wired it to the computer's USB 3.0 port.

This card reader has a slot for micro SD and full-sized SD cards. I have used it with a 64GB card with no issues. I like the protective shape as well.

This product provides quite a bit of functionality for the space taken. If you are looking for a multi card reader and want the little extra, well here it is. It was easy to install the instructions were clear and the cables where all labeled well. The only note to make is that it requires 3 internal USB slots to be fully functional. 2 for the USB slots on the front and 1 for the multi card reader which also is the one that powers the light for the fan/temp gauge.

I got this to read a Sony Memory Stick Pro Duo from an old camera, and it works just fine.  I like the short flexible cord for the USB connection.  I had an old card reader I used with a netbook, and the USB connection eventually loosened and failed.

When my previous card reader suddenly stopped working after I upgraded to Windows 10, I was looking for a fast USB 3.0 replacement that could reliably transfer files. This reader did the trick. And the cap is big and snug enough to not get lost, while not adding too much to the bulk of the reader.

I've been using a couple of Transcend 8 GB SDHC cards for over a year now and decided to get this to keep a small card reader in my camera bag. It works. My other cards have been reliable so I expect this one to be, too. The card reader transfers the images to my computers at full USB 2 speed.

What the product photo doesn't show is that the card reader is wide enough to crowd out adjacent USB ports. I expected the side with the card sticking out to keep me from using an adjacent port on one side. I didn't expect it to be wide enough to block the port on the other side too. It does, forcing me to pull another peripheral off my computer when I download photos. That's a minor annoyance. On the other hand the card reader adds little to the cost of the card it comes with. It's small, light, and it works.

Did not work with my square readers. Square app recognized the dongle but the dongle would not recognize the reader

I purchased this as a supported scanner for my Square system.  Works like a dream.  I can quick scan multiple items and streamline my check out process.  It does seem to wiggle a bit at the connection point, but think that the USB to Micro converter I have.  I love this barcode scanner!

Sometime I have to swipe 3 or 4 times for it to read but it always goes though. Very useful, I don't run a business but I use it between my friends and family because it is extremely convenient. Wish Square reader didn't take so much of transaction. 2.5 percent adds up

Bought this to work with my square stand - worked great, plugged it in and it was ready to go!
