Ten products. A teenager helping. No website. With one generic QR taped to the tent pole, Rosie is the checkout: every sale needs her eyes on a screen and her mouth saying "twenty-one dollars" for the eighth time that hour.
With a card next to each product, three customers can pay at once, right amount, right account, product name in the note, while Rosie keeps bagging purchases and her teenager helps at the table.
Her payment feed reads "$21.00, Honey 16oz (HNY-16)" twenty times over. She runs two Venmo accounts, @rosies-farm for the honey and jam and @rosie-candles for the candle side-business, and each card opens the correct Venmo payment handoff automatically.
