Such businesses are difficult to find, so my iPhone is inside a small case that opens to hold only three cards: my driver's license, a debit card and a credit card. No, it's not a man purse. It's the size of my phone, but about twice as thick. For me, it beats carrying around both a phone and a wallet.
But even with just one credit card on me, it's tempting to leave it at home and only carry my phone with me.
When I go to a business with a mobile card reader, I'm looking for one that uses Bluetooth technology to connect my mobile phone to its credit card reader so that the credit card stored on my phone can be seamlessly and securely used.
I'm looking for Bluetooth for two reasons: So I don't have to carry a physical credit card with me, and so I don't have to use the chip in the card and spend an inordinate amount of time at the cashier.
There's also a third reason, which I really did't think about much until I went to Europe last summer for vacation: High merchant fees for using a credit card.
