QR-only sign-up (scan, browse, leave) loses guests who don't want to type personal info on a tiny mobile form. Phone-only (cashier types it in) loses guests who feel exposed at the till. Combined (QR opens a one-field 'enter your phone' form pre-filled by autofill) hits the highest conversion.
In Vietnam, the combined flow auto-routes to Zalo OA after sign-up, which converts a one-time capture into a recurring channel. This compounds: every sign-up is now reachable for win-back at 90%+ read rate.
FAQ
What about email-only?
Email-only is the worst-converting flow in F&B by a wide margin (5–10%). Use email as a secondary capture, never primary.
The PEKO ecosystem
PEKO and LOOP are two products from the same company. PEKO is the AI retention layer and runs alongside the POS you already use. LOOP is the AI-native POS that covers operations: recipe-level inventory, staff shifts, table plans and the kitchen display. Each works on its own, and run together they share one dataset, so nothing has to be entered twice. See PEKO + LOOP in one ecosystem

Are paper stamp cards still worth using in 2026?
Only for pure walk-in venues with no repeat business to defend. Paper redemption runs under 15% versus 35–55% for digital, and paper leaves you with no way to contact a customer who stops coming.
