Can you talk a little bit about how you power the Dabbas and refresh the tokens if they are only valid for 24 days.

Do you guys function like "doodh wallahs" in that you visit the locations every morning to reset power and tokens? Would seem like a hassle but convenient from the point of view of the chai wallahs.

The dabbas are plugged into the wall for power, practically all tea shops tend to have a power line of some sort even if its not obvious at first glance. We provide a battery backup too. Our software handles refreshing of tokens, so no need to visit the store that often for maintainence.

The tokens seem to be physical. Does that mean you print them on the spot?

Edit: Addendum: Also, if they are physical, why did you consider physical over simply displaying them on a tiny screen? I can think of one reason, I can buy a token and activate it later at home.

Danm.. I remember going to Chai-wallahs and reactivating my dongle. Cost me a lot of money for very little bandwidth usage.
