I have always had a bad relationship with wallets. It was just one more thing I had to carry because there was no way to keep IDs and money organised in my pocket on its own. After one of my wallets wore to the point of me actually throwing it away, I decided I’d try to make the most efficient wallet ever.
Raise your hand if you know everything you’ve stuffed into your wallet (no peeking!). No? Then it’s time to do a wallet audit to make your life a lot less hellish if your wallet ever gets lost or stolen.
While everyone else is rushing to convert their wallets into data, one Instructables user was converting his wallet into data storage. By taking a cheap, ultra-thin USB flash drive dongle and sewing one tiny piece of Velcro, Instructables user “Activist” was able to upgrade his leather wallet into the 21st century.
The sewing bit makes the Velcro pad much more secure since you’re dealing with leather, but my guess is that you could probably do alright with some strong super glue, should you lack thimble skills.
