Wait, did they lift the print off the phone or actually photograph the guys finger? If it is a photograph then this means nothing...
I just used scotch tape and lifted a print off a glass, put a little talcum powder on it, held it over the reader with my finger and presto, retarded iPhone sensor fooled as easy as 1,2,3. Sorry, but even a 4-digit pass code is safer than this stupid POS. Apparently, Tim Cook and company never watched a cheesy spy movie or an episode of McGyver in their entire lives or they'd know how ridiculously easy it is to fool fingerprint sensors and how unsafe it is to allow purchases using them as a pass code. Thanks, but no thanks.
