Kick The Green Monster

Do you know who the Green Monster is? It’s that skunk-of-a-bill that you get at the end of the month; it devours all your Dollars because you overspent! Only if you could use something like the Live Checking Card! A Credit Card won’t let you go beyond your limits. It’s a digital thang with an E-ink display that allows you to check your payment history on it. It even tracks your bank account’s transaction through RFID. A cumulative amount shows up on the screen every time you swipe the card; giving you your account balance on your finger tips.

Designers: Jin-young Yoon, Wook-sun Oh, Young-ho Lee & Jun-kyo Lee

    nice, now thieves can check if is worth it to take you to the atm machine

  • Confucius says:

    I agree with freddy, and when do credit cards ever see the light of day? Solar panel is no good sorry.

  • Lamah says:

    Who in their right mind would want their account information to be broadcast with RFID?? You can’t strongly encrypt it because RFID doesn’t provide enough power for the card to decode it.

    The design ignores one of the major strengths of E-Ink displays—they require no power to maintain an image. The power only has to be applied when the balance changes. Ditch the solar panel. Have the card reader supply the power to update the display. You can use the preexisting “chip + pin” readers to provide a power and data connection.

    You have to leave it on the table, OUTSIDE for it to get energy from the sun. This is just another photoshop project.

    • Mountain sailor says:

      Solar panels can derive power from any light source with red wavelengths, not just the Sun.

  • Callie says:
