Personally, I'm not into a single point of failure device. Same reason why I eschew paying with a cell phone. More convenient? Sure. But lose your cell phone and you have a lot of things to account for, doubly so if you have no form of remote wiping it.

A wallet is a single point of failure device. It's a lot more of a hassle to remotely wipe my wallet (remember all the cards, cancel them all individually).

The same link has been submitted thrice with different accounts and upvoted to 3 points.

It appears the release was embargoed for 12PM EST, so it's not surprising that people submitted simultaneously. It is surprising, however, that all of them received a significant amount of upvotes.

It's not uncommon in this sort of situation for them all to get upvoted. Firstly, different people will upvote different ones, so if there's a popular story then a large number of upvoters split by 3 is still a decent number on each. Then there are people who will upvote more than one, either because they think it's important enough to deserve multiple links, or because they think the links offer enough difference in content, or because they upvote the first one they see, then see there's a better one (e.g. "oh shit, I upvoted blogspam, better upvote the official one now")

Crafty, I see what you tried to do there! UP-voted for the lol factor and the fact that I don't have a down vote button. ;)

I'm really unsure how this is any different than the multiaccount product here https://www.dynamicsinc.com/Corporate/Products

of course with the exception of it altering you if you left it at home, however that is a bit creepy, and, well let's just say I won't be getting a coin for my wife anytime soon

Don't forget there is also Loop, which reached it's Kickstarter goal already:

Personally, I like the idea of using my phone over the coin thingy.

Also, I'm curious about how sturdy this thing is. Maybe it's my wallet or maybe I just shop too much, but I tend to wear out my debit card really quickly (< 1 year).

Swipe, click-to-switch, swipe, click-to-switch, swipe... Why steal one card's data when you can copy the whole wallet? :-) Or, run one card but take down the information for another. It also appears that the Coin is programmed over Bluetooth. Why bother swiping to steal when you can run a smartphone app and take all of the cards on all of the coins in range? If this takes off and fraud goes up, credit card companies…

Because it doesn't broadcast credit card data over Bluetooth.

I wonder how this would fare in an ATM. What happens if the ATM accidentally presses the card selection button? If the ATM gobbles the card, now you've effectively lost your entire wallet. What happens if the cashier presses the card selection button while running your card too? Oops, now your boss wants to know why you've just paid for your groceries on the business credit card and why you've cloned your business cr…

Definitely agree with your points.

This might be solvable by making it a capacitance-based button.

This is very cool. However, in Jamaica where I live. An id is required to use a credit card, so they can check your name and your signature. Is there are way to displaying that info on the card.

Earlier quoted context omitted.

And how exactly is this verified? I don't think there's OCR there to verify that it's your card you just snapped a photo of.

Card.io will scan cards and OCR them. Maybe they do something like this to ensure the name matches the registered name on the account? https://www.card.io Edit: And it's on the magnetic data, too.

I go by my middle name, but some places have forced me to use my first name, so my cards are a mix of my first+last and middle+last name. So then I would look like two different people to this coin wallet?

I worked on a product like this at Amex about 20 years ago and while it was a totally neat concept it was completely stupid in practice. All those plastic cards are marketing vehicles that can also transmit a number. And, really, are they that difficult to manage?
