Bonus Card Hack

I spotted this the other day on Lifehacker (I guess it originated on Instructables) but didn't get a chance to write about it.

The basic concept involves moving all those barcode based Bonus Cards (like My Reward Zone and Supermarket Club Cards) onto a single card. The Instructables article goes in depth with setting up the card but you can also check out Just One Club Card for an online method.

The idea here can also be used for replacing older rubbed out cards. I had a Reward Zone card that was so abused it wouldn't scan - using either of these pages you could easily create a backup card or even a replacement.
