The South African grocery retailer Pick n Pay is expanding its Bitcoin coverage to all 1,628 stores across the country.

To pay with BTC, customers will need a Bitcoin Lightning Wallet and the CryptoQR scanner app from CryptoConvert, which is linked to the Bitcoin Lightning Wallet. The payment process requires users to scan an item’s QR code through the CryptoQR app and then proceed to the Lightning Wallet to confirm the rate and complete the transaction.
