Thank you for your reply cclemmer.
I suspect it will not be an iPad unfortunately. I would actually prefer it to be that as I know those are easy to support on the wireless infrastructure.
My suspicion is that it will be one of those standard units from ingenico or one of the others. I could be wrong though of course.
I will have to wait and see what device they suggest. I will also need to look into the PCI compliance as I am not familiar with that.
