A bento vending machine powered by Venmo 🍱
Bento vending machine that takes payment through Venmo and texts receipt to phone (using Venmo API). Vending machine is an insulated container with many locked flaps like a mailbox, with LED indicators above each flap. Choose the bento from a touch monitor and Venmo the account provided by the vendor. Machine will unlock a flap that allows customer to get bento after customer has paid.
Central controls and touch monitor will be in one module, with wires that can be easily attached to stackable modular insulated containers.
Update: Venmo switched to Stripe due to Venmo API deprecation and compatibility issues.
