A card instead of a phone.

Many collectors work from a truck or cart with no smartphone and no data. Operators issue them a physical EcoCredit card. The batch number identifies the person; the location is where they received it. Households sell to the card. Operators buy from the card. Same deposits table — collector_code on the row, no new login.

1. 01

   Issue at the yard

   Generate a batch for this location. Print or send the sheet on WhatsApp. Hand each card to a truck collector when they arrive.

2. 02

   Buy from households

   The collector shows the card. A household with the app logs the sale against the code. If nobody has a phone, the operator records it when the truck comes in.

3. 03

   Sell to operators

   Operator enters the same code when weighing in. Material, fee, and Paystack split attach to that collector without an account.
