I like the idea, but the first version seems quite limited. It is more of a GPS based webapp discovery tool. You click on the button, the app sends your GPS coordinate to the main server, which returns all useful webapps in the neighborhood.

I think that using NFC chips, which are extremely cheap, is very appropriate here. Use case: You point your phone to the vending machine/renting car and the respective webapp is shown automatically on your phone.

NFC is tough because you have to be within about an inch of it to get a reliable connection. For the use cases of a parking meter or vending machine it works, but for a bus stop or store it becomes yet another thing to stand in line for.

I haven't even had good luck with the parking meters in Seattle :(

I thought this works by each beacon broadcasting a URL with BLE, with the app sorting the received URLs by signal strength and not how you just described it. Correct me if I'm wrong, though!
