@ScottS I didn't buy the zenlet wallet ... as I mentioned I decided I didn't need it after slimming down and ditching most of my cards in favor of just the @onlycoin.
(Straying even further OT!)
@black_jaquar, coin is a great product, but with some drawbacks that prevent it from being a game changer so I have a very mixed review.
Extremely well built, solid, at least as thin as a credit card, durable. You get a sliding card reader to scan as many credit, debit, ATM or affinity cards as you want into the app. The app is synced/paired with the @cLin, and you can define up to 8 cards to load onto it. It seems to work at about 98% of the places I try it, but anything less than 100% means you still need a credit card in reserve for when it doesn't work.
The security is awesome. The card will lock up and not function if it's not within range of your phone, although if that ever fails (it doesn't) you can also tap in a morse code like password directly to the card and still use it. Once unlocked it is usable for about 7 minutes, plenty of time for the waiter to do his thing etc. For people who scream "but how can you trust him not to run a bunch of charges during those 7 minutes" that's exactly the same as how every credit card in the world works. But if you leave your @coin behind or if it's stolen, it's locked and secure, so unlike a credit card I have no problem leaving it laying on a table, or sticking it in my BUBM, or whatever. As a business traveler with a sometimes complicated life it's great to carry just one @coin but to be able to use my company's card, or my wife's, or a customer's, or the one I like for rewards points etc in each different circumstance.
This thing was delayed about two years before they shipped, and it came out just as changes were being implemented to make all the vendors require chip readers and also just when android, apple, and everyone else started coming out with exciting wireless payment solutions. It would have been revolutionary if it came out when promised, but by the time it came out the conversation had moved elsewhere. (Please hold the analogies to you know what - I think we still have more runway, perhaps even 2-3 years, before the input device conversation significantly moves elsewhere to for instance virtual reality, voice, gestures, or adaptable keys).
Even in the payment domain the @coin usefulness got extended because here in the USA the compliance with converting to chip terminals is still dismal. @coin added a wireless payment feature and gave everyone a free upgrade, but there are endless entanglements about which cards support NFC for which vendors etc so at least for me I can hardly ever use it.
Overall I love having it because it thins me down and I love the security features, but the actual functionality is defeated by the fact that on any given trip I'll always end up with a couple of charges on a card I had not intended so it sort runs as a counter benefit. It's massively fun that when needed I can "have with me" some obscure card that I didn't expect to need while nobody around me brought one, but I usually pay back that karma the next day when in front of the same colleagues my card fails to swipe.
