CryptoQR codes let people buy goods at PicknPay. They have 1600 stores in South Africa right now. They sell groceries, value added services, clothing, travel tickets, do bill payments, etc.

CryptoQR is a project by moneybadger.co.za and plans to expand.

Blink already supports scanning these QR codes. See code example here: https://github.com/GaloyMoney/galoy-client/pull/331/files
