Quite a few of us use multiple credit cards and every time one card expires, its plastic adds to the trash. So do the numerous receipts that we accumulate after swiping our CC. The fundamental of the One Card Electronic Card is quite simple; it wants to eliminate the trash (and resolve issues like identity theft via discarded expired CCs) by proposing to be this all-credit-cards-in-one device. On one end of the gadget is a Memory Card Slot that will help the user upload their various CC Details.
The other end has a turning-knob that allows one to choose the appropriate Credit Card to be swiped. The display on the device reflects an identical copy of the CC front, while the strip on the back mimics a CC’s magnetic strip. Once the transaction is completed, the receipt generated is displayed on the device (no paper receipt) and the info gets stored on the memory card.
The concept is pretty clear in what it wants to achieve, namely combine all cards that a person uses under one umbrella, reduce generation of paper/plastic trash, identity security etc. The only block is the compatibility with various banks and the willingness of people to rely on a gadget for daily CC transactions. Yes, we do use online, virtual services, but something like this is quite different.
