Hope it works out well and has good cybersecurity

QR Code payment has become commonplace here. Places that accept card payments automatically accept QR Code payment (all EDC terminals can show QR codes on the screen, or print it if it doesn’t have a big screen), and place that don’t accept card payment often accept QR payment (they just put a QR code sticker somewhere and ask the customer to enter payment amount manually when they scan it). All banks support it, and there are several non-banking “e-wallet” providers as well. And the merchant fee is low too, ~0.3% for small businesses (used to be free), far lower than what Visa/Mastercard charge.
