Forum:Duel Terminal QR codes?

Several articles (such as Duel Terminal - Preview) mention very faint QR codes at the center of Duel Terminal cards. Could anyone upload an image showing one of these codes (and in the meantime, could someone confirm whether these are QR Codes, and if so, what information do they actually encode)? Are they unique per individual card, or is the same code used for all of one card in a set (in which case, should we document these in the same way we document card numbers and passcodes)? 「 ダイノ ガイ 千？！ 」? · ☎ Dinoguy1000 04:55, February 16, 2011 (UTC)
