Okay, this is now a new design requirement for all upcoming console devices – your console should not interfere with the store management systems of the world’s largest softare (and everything else) retailer:

A spokesperson for the retailer told Next Generation, “As we began setting the Xbox 360 up in sample kiosks in our stores we’ve found that, in a handful of  some of our older stores, the devices are interfering with our Telzon printouts. We’re working with Microsoft to correct this and should have Xbox sample kiosks available and working in all of our locations in the next few weeks.”

See, this is exactly the sort of thing that probably doesn’t appear in any QA plan anywhere in the world – until now.
