Experimental Credit Card Design Glows Hotter with Higher Balance
Consumers might think twice about swiping a credit card that glows like a hot stove. That's one of the ideas behind designer Park Mi-na's concept of the "Tricard Visa," a credit card that uses electronic ink and LED technology to change its color and its printed details as a cardholder makes purchases or payments.

Featured on the Yanko Design weblog, the Tricard Visa would hold consumers accountable to their own spending with two information displays. An e-ink number in the center of the card displays a customer's balance in numbers big enough to provoke a reaction from fellow shoppers. A red LED offers accent lighting that gets brighter as a cardholder approaches his or her maximum credit line.

Shoppers about to max out their credit line would be forced to hand over a bright red Tricard Visa to a cashier. Consumers with more balanced credit habits would enjoy the opportunity to swipe a "cooler" Tricard that more closely resembles one of American Express' premium clear or black cards. While the design may never reach any actual wallets, personal finance blogs have buzzed about the pros and cons of a credit card that reveals such personal details.
