How many debit, credit, loyalty or other magnetic strip cards do you have in your wallet? The Protean Echo is a concept designed to lighten your wallet, but in a good way. Due to be put up as a funding project on Kickstarter in Winter, the Echo system allows you to scan all your magnetic data from your cards into your smartphone and then sync any three cards to your Echo. By pressing one of the three buttons on the card, the Echo takes on the “personality” of that card. The Echo can then be swiped just like you would normally with your card. You can easily sync the Echo to your phone to change cards at any time.
To me, there’s still a number of security issues to take in to consideration here, but at an expected cost of between $80 – $100 it certainly looks like an interesting concept.
