A hand keyed card number is much more open to chargebacks. Swiping the card proves the physical presence of the card. I am certain they'll use a card reader, I can't imagine how their cc processor would allow all those hand keyed transactions.
I was really hoping that the announcement of copy/paste and MMS would STOP people from complaining about these features not existing.
(features that I personally haven't missed one bit in two years of use)
