These live checking cards could change the way that people budget their money and make it easier to eliminate debt. It shows you very clearly what you’re spending and what you owe. The concept was created by several designers at Yanko Design.
In addition to being a credit card, it would also track bank transactions through RFID. Amounts would be displayed on the card every time it is swiped, allowing you to have your account balance at your fingertips. The card uses E-Ink technology combined with RFID technology.
