re: Consumers Say Smartphone Payments Will Replace Cash and Cards, Study Finds
If I could ditch my regular wallet for a smartphone/digital wallet, I would do it in a heartbeat. First, a digital wallet/smartphone is more secure than a regular wallet. If you lose it it has a passcode and can be wiped remotely. If you lose your regular wallet, good luck.
However, Apple's Passbook is a joke (there are like 15 companies participating in it). And Google Wallet intentionally excludes iOS devices.
So it looks like I'll continue to carry my regular old wallet for some time.
