Double-up programs incentivize healthier food purchases for SNAP recipients by doubling the purchasing power for fresh fruits and vegetables (local conditions vary). The stores get reimbursed for their foregone sales from program grants.

Several of these programs use the Credibles app to settle the credits for double-up purchases at corner stores, bodegas, and farm stands (which typically lack sophisticated POS systems).

Example of a Double-up Food Bucks program.
