Coin Card Review


The mobile payments segment has seen considerable attention the last couple of years, exploding to a frenzy where we have numerous options to pick. While Apple Pay seems to be making significant penetration, other services haven’t received the same kind of success, but choice is always a good thing.

Cash is always a preferred form of payment, as well as credit/debit cards, as most merchants and retailers accept them without question. With that in mind, that’s where the idea of the Coin Card was born – the one card to rule them all. Introduced back in November 2013, the Coin Card is a secure, connected device that consolidates all of your credit cards, gift cards, loyalty cards, and much more onto a single card.

  • Card reader
  • Get started guide

The wait was long, almost unbearable

Before we dive into this review, let’s first explain our experience with actually obtaining a Coin Card. When we think about 2013, it’s almost hard to believe that’s when Coin was officially introduced – more so considering we’re at mid-2015. Soon after the startup began accepting pre-orders for Coin, we weren’t hesitant to fork over a $50 pledge to guarantee ourselves a unit, when they became available, of course.

Long story short, we were promised on several occasions that our Coin was finally coming, only to be disappointed on occasion about it being delayed. At long last, Coin finally informed us that they were shipping out our unit this month – a grueling 1.5 years after making that initial pledge. For a time there, we forgot about it and gave up hope on ever seeing it, so needless to say, we were ecstatic to see it at our doorstep.


Coin looks exactly like any other credit/debit card you already have, which is pretty astounding considering that they’re able to stuff all of the electrical components, display, and battery into something that has the same thinness of any ordinary credit card. Add to that, the slick almost all-black front of Coin makes it unique looking amongst credit cards.

On the back, there’s the magnetic strip and signature line – the common layout of every credit/debit card. Meanwhile, there’s a single circular sized button around the front, just a little below the display, that ‘turns on’ Coin.

Plastic in nature, the design is commendable on so many fronts. It doesn’t look like some sort of electronic gadget, which makes it discrete to the point that most merchants don’t even recognize that there’s something different, or special about it – that’s unless they see the display, obviously.


Speaking of the display, it’s a tiny LCD that only displays the name of the card you want to use, the expiration date, and the last 4 digits of the card number. Pressing on the button beneath it allows us to cycle through all the cards stored in Coin. What’s nice, though, about this specific implementation is that the entire card number isn’t displayed – nor is the CVV numbers that’s usually situated in the rear of most credit cards.

Too bad the PA author is unaware of the proper use of common English punctuation marks.

5 failures in a week?!? Works at some places no problem, but failed to read the mag strip @5 separate POS terminals within the 1st week using the same stored credit card. This simply isn't ready for prime time. Don't waste your $$. And to top it off COIN isn't standing behind their barely functional product. No refund for you!

Thankfully I cancelled my order after constant push back of the release date. Good idea, but poor execution

It's July, 2015 as I type this. Magnetic stripe cards - which is exactly what Coin emulates - will ostensibly be obsolete in the United States in October due to the EMV liability shift. I am fairly confident at this point that I will not receive mine before then. Coin is the quintessential example of "Clown Funding." It's just like Crowd Funding, except that instead of getting what you were promised, you get a poke in the eye.

When exactly will they have a RFID chip..? I thought this was going to be a way to take all your cards and not worry about having strip issues as it would be using RFID like they do in Europe and SOME new US Credit Cards..? If it just converts swiped cards into A swipe card.. count me out.

Also too bad this was designed basically just for the US market, as the EMV chip is pretty much standard now everywhere else that the debit and credit card is in prevalent. I don't have a single card without a EMV chip requiring a Pin.

I threw my $55 dollars in over a year and a half ago. I was promised the card time and time again and skipped over for the beta. I finally decided to get a refund. Because so much time had passed, the debit card I used had been replaced by my bank and now had a new number. I was promised a check. I waited weeks and no check arrived. I sent multiple emails and each time was promised it would be forwarded to the "Payments team". No reply or check. Eventually they started ignoring my emails altogether. I had to file a complaint with the Better Business Bureau in San Francisco again OnlyCoin. Even after that it took yet another month before they finally sent an email asking for my Paypal address. What a joke this company is. I would never purchase a product from them even if it was actually "shipping".

This is a pretty good review. When I got my Coin (after a very long wait) I found it pretty easy to set up. But it still has some major problems. One of my cards consistently asked for the CVV - even though I am using it as a credit card. I have tried to use the card in multiple venues and it works in about 80% of the locations tried. Indeed, even in one location the card worked on one night and not on another. If this product wants to be successful it needs to be able work in almost 100% of the places it is tried. And at the same time, it needs to recognize that competition from Apple Pay and Google Wallet and the new Google technology for the phone - will challenge this product if it does not get everything substantially right. The 2.0 version will have an NFC chip in it and hopefully that may clear up some of the problems I've had with card readers. But at this point this product is not ready for prime time.

Not compatible with my Samsung Galaxy 5 so I had to ask for a refund, which has been promised. The issue was that the card would not sync with the phone. The symptom was that after the initial SYNC display, the card went straight to dashes, which is indicative of a false SYNC. I had two cards--same symptom on both! Great idea, poor execution, I think.
