Samsung demos OLED security card
Powered by an RFID reader?
Samsung has demoed an electronic ID card with integrated low-power OLED.

The credit card-sized ID has a 2in, 240 x 320 OLED screen embedded into it that displays a slowly spinning woman’s head.
Presumably the card also has an RFID chip embedded into it, because – according to various online reports - the display requires such a small amount of power that it can be driven by an RFID reader.
It’s not yet known if Samsung plans to develop the technology commercially, but one shot in the video hints that the firm wants to substitute all traditional photograph IDs with its OLED IDs. ®

On second thoughts
Alright, maybe I was too jumpy. Its still a daft application, but certainly a very nice demo application. I'm just fearful of the day of having shelves of singing yogurt pots. Its coming, and its going to start with tech like this.

Because, why not have the screen attached to the RFID reader to view the image on the card.
Why have it on the card.
Just because it is powered by an RFID electric field doesn't mean it has an RFID chip.

It could just use the induced current to power the display, meaning it would just have the antenna function, not the ID function.
The Devil is in the detail
(The title is not an 'Exorcist' joke.....well, maybe a little..) Does it use an industry standard RFID reader or have they pumped up the power output for this one? I notice the demo guy has to reach way back to put the card on the display stand. Is this because they need a darkened area to enable viewing; or is it to prevent people's fleshy bits from being harmed by the radiated power density levels at the card surface?
(AFAIK, OLED displays are suitable for viewing in high ambient light conditions, hence my suspicions)
Looks ok but...
What happens when someone absentmindedly puts the thing in their back pocket. 'Crack!'
Unless these are super flexible OLEDs, I think that there is still a long way to go before these are anything more than a proof of concept.
