the codes have to be unique alphanumeric like this sort of thing
M6YKX305U1EU
T44GR17DB7G0
X9THPVTDKY72
Y7743AGKPSMO
4QAMDZNNXP0U
they then get digitally overprinted on collect card that the public get in pagkaging then the sms or enter on the web to win prizes and earn points
i can generate the codes but i then need to scan the code to remove letters and numbers that the public can get wrong on the entry procces ie 1 I G 6 and things like that, also need to scan all code to make sure that there is no dups
cheers
