Long time reader and first time posting but figured this audience caries a lot of credit cards. There's a new product: Coin. It combines all your cards into one electronic card. At purchase you can choose which card to use. It's got some cool features and they are offering them for half price ($55 with shipping, normal will be $105) right now in a limited pre-sale. Unfortunately they won't ship until summer 2014. I'd greatly appreciate people using my referral link for this: https://onlycoin.com/?referral=VoShcxgA Thanks! Edit: Forgot to note, this card has no chip and is targeted at the USA. Presumably the swiping will work while abroad though. It holds 8 cards, which lets me lighten my wallet considerably. I suppose you could get more than one and reduce your card weight to 1/8 of what it is now. Additional edit: This is pre-sale is a crowdfunding venture to get the start up going. Technically there is a risk that you will not receive a card and not get your money back. The goal though is $50,000 (here) which is only 1,000 cards which seems more than feasible to me.
