Jimi wallet. End of. Forces you to remove all the crap and just carry essential stuff. Mine has my debit card, my building society card, an Oyster card and my security RFID door pass for work and my drivers licence on one side, and folded cash, a couple of coffee loyalty cards and some stamps on the other. Attached to an Animal lanyard that’s looped around my belt, it’s perfect, as I have to pull it out of my pocket several dozen times every day to open various internal doors at work. I wrecked an Oakley wallet by trying to cram loads of change in it, and it bulged with useless bits of paper.
Jimi FTW.
