Your fat wallet wants to meet Plastc -- a device which its manufacturers claim can replace most of the credit/gift/loyalty cards you currently mule about. It works by pairing with an app on your phone (via Bluetooth), which provides near unlimited storage for all your cards (Plastc itself can only store up to 20). The app also logs your transaction history. Does this all sound a little familiar? That's because you're probably recalling a similar device called Coin launched back in 2013. Just like Plastc, it, too, can store various card details that you can call up, depending on which one you want to use. The bad news is that Coin, which promised to ship the first units this year, moved its ETA to spring 2015 (though there's a beta test going on) -- something pre-order customers obviously weren't happy with. So, one has to wonder if an unknown company will be able to do what Coin couldn't and release such an ambitious product on time?
