Heck Yeah! Infact, we expect most of your fans will use your cards over their mobile devices. All your fan has to do is scans the QR Code on the back of your card - and pow, the access code shown on the card automatically appears in for them to unlock their card. If your fan can't scan the QR CODE, they can enter url and access code manually as well. Its up to them. But we think just scan and download is much easier! Plus - we also have NFC (Near Field Communication) chips embed in download cards. This makes it even easier for a fan to use with their mobile device.
