POS Tap to Pay — Contactless NFC on Mobile Devices

This is a build-to-order module that ECOSIRE designs and builds for your specific environment. On the backend we add a dedicated contactless payment method that extends pos.payment.method and pos.payment, plus the models and res.config.settings fields needed to hold reader credentials, merchant and terminal identifiers, and per-pos.config routing. The payment provider's on-device software SDK is wrapped behind a thin service layer so the OWL POS front end can request a payment, hand off to the NFC tap, and receive an authoritative authorization result — success, decline, timeout or cancel — that we write back onto the order together with the provider transaction reference, card scheme, last-four and auth code. State is reconciled defensively: a fetch/poll fallback resolves the transaction status if the device loses focus mid-tap, and idempotency keys prevent a retried tap from double-charging. Refunds and voids are wired to the same method so a negative POS order routes a contactless refund rather than forcing a manual back-office adjustment.

Security and reporting follow Odoo conventions rather than bolt-ons. Access to the payment configuration is gated through ir.model.access.csv and record rules so only Point of Sale managers can view or edit reader credentials, and secrets are stored server-side and never shipped to the browser bundle. Transaction metadata flows into the standard pos.payment reporting and your journals, so contactless takings appear in the existing POS session close and accounting entries with no parallel spreadsheet. Where your provider exposes a webhook or settlement feed, we can add an inbound controller and an automated action to reconcile captured-versus-settled amounts. Everything is delivered as a proper installable module with its own __manifest__.py, versioned for Odoo 17.0, 18.0 or 19.0, and we confirm Community-versus-Enterprise assumptions up front since device and POS-session behavior differs between them.

Delivery is build-to-order. We start with a short scoping call to pin down your payment provider and reader hardware, the device platform your floor staff actually use, tipping and refund rules, multi-company or multi-shop routing, and the Odoo version and edition you run. From confirmed scope, typical delivery is 2–4 weeks: we build against a staging copy of your database, run UAT with your team, then install to production behind a rollback plan and hand over the git repository. Pricing starts from $299 (indicative, single-company base scope); additional payment providers or reader models, multi-company and multi-shop routing, deep tipping/loyalty logic, and settlement-reconciliation integrations increase the quoted scope. You receive a fixed quote after the scoping call — never a surprise invoice.
