I read an article on Slashdot the other day that lead me to a couple of articles on e-paper. Its very interesting stuff and if they could get the cost down it will be very useful. I then started thinking about e-paper in conjunction with daily lubricants, and came with, what I think, is an interesting idea.

The days of balancing your checkbook have started to go by the wayside as people begin to manage their finances in real time. Looking at your checking account for 5 minutes a day can free up a few hours of one weekend a month. What if it took less than 5 minutes? What if your credit card/debit card had a display on the back that showed your last 10 purchases and your current balance? How do you do it? Wi-fi/Bluetooth + epaper + smart card. You’ve got some privacy issues to deal with(maybe the ink fades after 30 minutes), but I think it would help some people out. You have to spend less time looking at your balances online and the $10,000 balance on the MasterCard staring you in the face might persuade you from buying that Grande Latte that don’t REALLY need.

You heard it here first, self updating credit and debit card, © 2004 Austin Fatheree, Patent Pending, etc.

That is all well and good, but what are some other ways that we can use this concept of self updating epaper to make our lives easier? People keep talking about how this will change the way that we read books, but I think that it is going to make a much bigger impact in other areas first.
