what is receipt id

[yichaoyu]

I wanna know what the receipt id is. Is that the id specified by the vendor, like the receipt # on a real receipt? Or it is just the index we use in our system. Because I assume it as the former one, I show the receipt id on the receipt on the cellphone.

For the prototype, it may not be a big deal. But I want to know and do the correct documentation for the mobile app.

it's actually an index we use. I'm adding another column for the receipt, indicating the real receipt #. I'll update the database later, including other new fields
