Startup Idea : One QR code

There are lot of apps that business can make use of to gain one or another benefit. But imagine this: restaurant has agreed on a deal with 3 apps and all of them needs a QR code presented on a table, now from restaurant manager's perspective that is not cool. Table will look like one big QR code. What about service that would allow you to generate a QR code and once it is scanned user would be presented to select which service user wants to use. And every new service that would need to hook in would come to this service instead of placing one more QR code on restaurants table.
