The photo that matters for FaceCash is the one that is downloaded from the server onto the POS. The one on the phone is just for show, and cashiers are instructed to basically ignore it. So if you're a thief, you can't just put a JPEG of your thief-face next to someone else's barcode. The correct owner's face will still show up on the register.
