The COIN card: Merge all your credit & debit cards into a single card

Coin Card

A couple of days ago a friend sent me a message saying, “you are going to love this” and he was right. I do love it and I just bought it. 🙂

They are on pre-order now, so I haven’t had a chance to play with it yet, but I will do a more thorough review of it when I get it.

So what is the Coin Card?

It is a credit-card like device that holds the information of up to 8 other credit, debit, loyalty, and gift cards.  So essentially it is one card to rule them all.

The card also has technology built into it that connects to your phone and will notify you if your Coin card gets left behind somewhere.

From their website: “Coin is a connected device that can hold and behave like the cards you already carry. Coin works with your debit cards, credit cards, gift cards, loyalty cards and membership cards. Instead of carrying several cards you carry one Coin. Multiple accounts and information all in one place.”

The cost?

It is a brand new product and they will be charging $100 in the future, but for the early adopters we can get it for $50.

Other Q and A’s

How do I get my cards onto my Coin card?

They have a mobile app will allow you to add, manage and sync the cards that you choose to store on your Coin. You add cards by taking a picture and swiping the card through a device that they give you along with the card.

What card details does the Coin display?

The Coin card has a little screen that displays the last 4 digits of the card, the expiration date, and the CVV.

Where can I use Coin?

“You can use a Coin everywhere cards are accepted including dip-style card readers and ATMs. Use a Coin just like you use your cards now at gas stations, restaurants, the mall, the gym, or other places you frequent.”

Will Coin affect my card’s loyalty or rewards program?

Apparently you can use it just the same and you will accumulate points and rewards the same.

Is a Coin really the same size as a typical credit card?

Yes. The dimensions of a Coin are roughly 80.5 mm x 54 mm x 0.84 mm or 3.125″ x 2.125″ x 0.033″.

What mobile platforms will Coin support?

Iphones and Androids.  Maybe Windows phones in the future.

Will the coin card work in an ATM?


How long does it last?

They are designed to last for 2 years and then will need to be replaced.

How secure is it?

From their website: “Maintaining the integrity of your Coin’s data is critical to your peace of mind. That’s why our servers, mobile apps and the Coin itself use 128-bit or 256-bit encryption for all storage and communication (http and bluetooth). Additionally Coin can alert you in the event that you leave it somewhere.”

What if I lose my Coin or someone steals it?

“In the event that your Coin loses contact with your phone for a period of time that you configure in the Coin mobile app, it will automatically deactivate itself.”

    This is a great idea for convenience, but there are a few points that I can think of that are big enough negatives that outweigh the positives. It’s a great idea for a tried & true technology (Bluetooth), but it opens up more risk and costs a bit of money for a small gain.

    1. It seems really easy to switch between different stored credit cards. That’s great for the owner, but is it too easy for a waitress to ‘bump’ the button and switch it? Would feeding the Coin into an ATM jostle the button? Maybe it’s not a button but measures conductivity like a touch pad, but I would like this to be explained better. The website says jostling Coin shouldn’t activate it, but restaurant staff may not be looking closely when handling cards to avoid a button.

    2. Security has to be important, and having it continually tethered to your phone is useful. However, should you ever lose your phone or if your phone dies (battery or damage), you have a set amount of time before your Coin will deactivate. I don’t always carry my phone with me. Also, since it doesn’t protect from card skimming via magnetic strip any more than normal credit cards, I don’t see much security added anyways. In the event of a lost Coin, you’d still have to call all your credit card companies stored to freeze the accounts because you don’t know how quickly your information could have been stolen, and you’d lose the $50/$100 of the Coin.

    3. More use of the Coin will drain the battery more, and spending $50/yr ($100/2yrs) to carry less cards in my wallet is not a strong value-added use of my money.

    4. Not waterproof. Credit cards are great to travel with and sometimes it is nice to not have to worry if you’ve left your wallet in your pocket as it goes through the wash.

    5. Needs protection to be in my back pocket. It’s fairly durable, but still an electronic device that could crack more easily and break. It’s free to replace credit cards often.

    6. No chip & pin for international travel. It’s coming supposedly, but not currently developed.

    Thanks for reading – just a few thoughts.

      I agree. No sale.

      Wow, good points Nicholas. Like I said I bought one and am looking forward to trying it out at which point I will be able to comment on #1 and #5 at least. I will say my biggest beef with it is that it only lasts ~ 2 years, but as someone who is obsessed with having a skinny wallet, I think it is worth a shot – so like I said i’ll do a review after I get it and use it a bit.

    • Patty

      I will be waiting for your review when you have used the card.
      It sounds “too good” to be true.

  2. Julie

    Nicholas brings up excellent points. I only thought of “needs to be replaced every 2 years.” WHAAAAT?! Won’t that negate the value of rewards cards?! What’s the point of getting a free burrito every 12th time or $1 off my latte once in a while?

  3. Janice

    Sounds interesting except that not everyone has a smart phone…

  4. Joseph Lalonde

    Sounds really interesting but I think the 2 year life span is a deal breaker.

    As for loyalty cards, there are some great smartphone apps to slim the wallet. KeyRing is an excellent choice.

    it helps. Thanks.

    Hopefully you will get it…ordered one in November 2013 and it is now August 2014 and still nothing!!!!

    • Bob

      Same here Diane – I am kind of annoyed 😉
