Rosie sells honey, jam, and candles at two markets a week. Ten products, a teenager helping, no website. With one QR on the tent pole, Rosie is the checkout — every sale needs her eyes on a screen.
With a card next to each product, three customers pay at once — right amount, right account, product name in the note — while her hands bag and her kid runs the table alone. Two Venmo accounts, @rosies-farm and @rosie-candles, and each card pays the right one automatically.
