Samsung has been showing their OLED e-passport (or ID card) prototype for a long time, and now we found this nice video which gives some more details.

It turns out that the flexible OLED is 2" QVGA 240x320, 260K colors and 10,000: contrast ratio. The display is so low on power it uses just the RF power - it automatically powers up when closed to the RFID reader.

There's still no details on when this will become a real product...
