There are three integration depths in 2026: (1) direct API sync (real-time order data flows into loyalty), (2) export-on-schedule (CSV pull every few hours), (3) QR-based standalone (loyalty captures the receipt at the till, POS untouched). Most operators don't need depth (1) on day one — depth (3) ships in 15 minutes and unlocks 80% of the value.
PEKO ships with native connectors for KiotViet, iPOS, Sapo, LOOP, Square, and Toast. Loyverse and others sync via CSV. The QR path means even pen-and-paper venues can run a full loyalty + AI win-back program with no infrastructure changes.
FAQ
Do I lose features if I use the QR path instead of direct API?
Only granular ticket-line analytics. Visit count, frequency, RFM, and AI churn prediction all work fine on QR check-ins.
How long does a direct POS integration take?
For supported POS (KiotViet, iPOS, Square, Toast, LOOP) — under an hour, automated. Custom POS — 1–2 weeks via PEKO's open ingest API.

Turn this into repeat visits
PEKO is the AI retention layer that runs on the POS you already use: it enrols members without the cashier asking and re-engages customers who are drifting away. Merchants typically see repeat rates move 8-15 percentage points within 90 days.

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

Answer
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.
