There are great aspirations being made in the direction towards digital and away from tangible money. But can this be done in a simple and secure way, while still keeping the tangibility and transparency of paper money?
Triia is a secure payment bracelet, which acts like a wallet for your digital cash. It can be used for daily payments, money transfers between people and as authentication for other banking services. The main benefit of having a bracelet is that it's a part of you and therefore more difficult to forget, lose or steal. To put money on the bracelet you would use your own mobile phone or computer to minimize theft risks. But to make the bracelet virtually impossible to hack it uses the vein patterns around your wrist to identify you. This means that only you can use it and stealing one would be pointless.
Instead of a screen the bracelet projects information onto your skin, makes use of the thermoelectric effect to charge itself and uses finger gestures as input. As you show numbers with your fingers, you also move the tendons on your forearm where the bracelet reads the changes with pressure sensors. With the onset of 3D printing technology each bracelet can be custom made for each user, fitting his or her style and wrist perfectly.
All the technology and infrastructure for such a system already exists, it just hasn't been put together in such an constellation until now.
