QR code vs phone number for loyalty sign-up — which converts better?
Viết bởi PEKO Team.Cập nhật lần cuối: 21/05/2026.
QR + phone-number capture combined converts 2–3× better than either alone. The QR removes the friction of typing a URL; the phone number unlocks Zalo/SMS reach for win-back. Skip either one and you leave 30–50% of sign-ups on the table.

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.
Câu hỏi thường gặp
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.

Answer
How do I roll out a loyalty program across multiple restaurant locations?
Pilot at one strong location for 30 days to nail the playbook, then roll out 2–3 locations per week using the proven template. Centralise rewards and analytics; let each location override only the local copy and offer mix.
Answer
Booksy vs Fresha for Vietnam salons — which booking platform?
Booksy has stronger directory discovery in some markets; Fresha has stronger product breadth and free pricing. Both lack deep Vietnam-specific retention — pair whichever you choose with a local loyalty layer like PEKO for Zalo OA reach.
Answer
Booksy vs Vagaro for barbershops?
Booksy is barbershop-native with strong directory traffic; Vagaro is broader beauty + fitness. For Vietnam barbershops, both work as the calendar — and both need a loyalty layer for the Vietnam-specific rebook + Zalo OA work.
