“This is what PERRY does, by laminating an e-ink display onto the card; the same flow of current through the radio-frequency antenna that energizes the card’s logic also updates the display. And since e-ink is “non-volatile” — the display only draws power during a change of state — the new value ought to be legible for weeks or even months thereafter.” - Urbanscale
My mind has just been blown. I now want e-ink RFID-powered index cards, and I want them yesterday.
Agreed. Imagine this applied to airline boarding passes, so that your boarding pass updates if your departure date or time changes - no more running across the airport because you didn’t hear the announcement in time.
Or how about price stickers in shops? You wouldn’t need to walk around with a price gun, updating prices every week.
