The instructables wallet challenge has some great entries, I like this one that’s not really a wallet at all… Johnsuri writes –
toss the wallet. it’s day is over. this is a bona fide, fully functioning wallet replacement, not just a supercharged key chain.
some personality quirks nourish love, credit cards lost in harvard square, porter square, davis square and goverment center do not. in order to save a love strained by the constant reliance on the honesty of wage slave clerks, i needed a solution fast.
i thought if i attached her cards to her keys this would ensure that if she did leave them she would soon realize her mistake when she couldn’t get into the car or house.
i was even willing to throw money at the problem, however, all the store bought solutions either broke quickly or were too bulky.
i thought about a key ring, but the cards needed to be easily removed if she visited an atm or summoned by a police officer.
finally i came upon the straight gate carbiner–small enough to fit in your pocket and able to thread a 1/4″ punch hole.
Just a couple notes, we’ve had no problems with wear on the magnetic strips and as long as the cards are aligned the holes do not abrade keeping the cards intact.
