What I mean is that at the moment each student receives printed a credit card side 6 times ticket. Each time they come, they have to show it to the teacher to get a stamp. Once is used, they receive another one, and so on.
I have been looking for a system like this for many months, in addition to the Dance Perofrmance event, we would like to use it for the above purpose.
I understand that the system produces a QR code that can be hung and scanned by entrants. Would it work for dance school?
One more question. Do you support Japanese and is it possible to set up everything in that language from receiving emails to anything that customers see?

Thank you
