Here’s a little gadget for those who drag their smart phones everywhere (and who does not?) But want to avoid having their pockets as big as this.
The iPhone case CandyShell has a compartment capable of storing a three-card format standard credit or debit card, driver’s license, Medicare card, etc.. The interior of this compartment is made of rubber to keep the map (s) in place and thus replace a portfolio – provided they are the type to go out without cash and not to carry 75 cards with oneself all times. (I dare not even count the cards that I carry in my wallet, it discourages me.)
