I'm interested in this thread and what you guys figure out. I'm thinking about trying to make a key fob sized device that has e-ink and stores all my "rewards card" barcodes in it. Then you could push a button to cycle through your 'cards' and have them scanned at checkout. I want this because I never actually register my cards and give them my address or phone number and using 503-867-5309 isn't working because the accounts keep getting deleted (go figure).

I was thinking this could be something powered by a coin cell, with a small microcontroller and hopefully no external memory. Something that could be taped with double-sided sticky tape, I think there are some low-power AVRs that can do deep-sleep while still ticking, I don't need precise timing, it can be +- several/tens of minutes. _______________________________________________ dorkbotpdx-blabber mailing list [email protected] http://music.columbia.edu/mailman/listinfo/dorkbotpdx-blabber _______________________________________________ dorkbotpdx-blabber mailing list [email protected] http://music.columbia.edu/mailman/listinfo/dorkbotpdx-blabber
