SMI #006: Replace Cash Tipping with Airdrop

Replace Cash, Venmo, and QR codes with location based tipping

Pitch in a Tweet:

Create a frictionless way to reward great service when you have no cash. Despite progress in virtual payments, like Apple Pay, Square, and Venmo, cashless tipping options are still socially awkward and technologically clumsy interactions. Tip using “Airdrop” through Bluetooth.
