Smart coolers feel like magic, but the tech behind them is well-understood: a combination of interior cameras, weight sensors, and a trained vision model that recognizes every SKU you stock.
When a member taps their card, the door unlocks. As they remove items, the cameras track movement and the model identifies each product. When the door closes, the basket is finalized and the card is charged automatically.
Modern systems hit 99%+ accuracy, and any disputed transaction can be reviewed via session video. The result is a shopping experience faster than self-checkout, with shrink rates that legacy vending operators dream about.
