Banker bot getting closer

Here we have the coin card which can store all your credits cards onto one SmartCard. It cannot hold cash, yet, but I am sure that is in the works. So, good for Coin.  My comments continue below.

Gizmag: Although things like NFC-enabled smartphones are making this less of an issue, the fact is that most of us still carry around a wallet full of credit, debit, loyalty or other cards that we routinely have to rifle through. That's why the Coin was invented. It's a single card-shaped device, on which all your other cards can be stored and accessed electronically.
Upon first getting the Coin, users start by attaching an included card-swipe dongle to their iOS or Android smartphone (or tablet), then using it to swipe their cards – they also use the phone's camera to take a photos of those cards. This process allows the information for each card to be stored on the phone, via a dedicated app. That data is then transferred from the phone to the Coin, where it's protected by 128-bit encryption.
The app also lets users add or delete cards, as needed. Up to eight cards can be stored on the Coin at once.
When users subsequently need to pay for something, they just press a central button on the Coin to toggle through the stored cards, with the name of each one appearing on a small LCD display. When they get to the one they want, they just swipe the Coin like they would normally, anywhere that regular cards are accepted – a chip-and-pin version isn't available yet, but it's apparently in the works.

How do we make this a full fledged banker bot? Well, just add the server protocol to the card so that it can accept transactions and balance accounts. Then the Coin device has code to handle both sides of the transaction.  But make the Coin device counterfeit proof. I am certain they have that operating in the lab, so  pester them. They also have a new challenger, so the market is expanding. Once they have this set up, I will send it to the mathematicians and they will install a fully intelligent Black-Scholes account balancer for multiple currencies.

But they still need an almost secure hardware key built in, and expiration codes to prevent brek-in.  Each coin card must securely identify itself as a balanced account banker bot.
