Automatically like a page in Facebook based on user long live token

As the title reads...

is this possibly?

Workflow should be like:

1.- User is registered, he receives a barcode with a numeric ID.

2.- Time later the user scans barcode in embedded device, it posts the numeric ID to some php magic... and he automatically is开发者_Go百科 noted as "liking" (user likes x) a certain page, no login, no nothing, we should get the user data just based on our first registration. The (embedded device/computer/thing that reads barcodes) must be headless.

Is this even possibly with the current Facebook oAuth model??

Thanks in advance.
