Private by design • Secure by default

Effortless digital receipts with a single tap

e‑me links in‑store payments to your identity after checkout — no emails to spell, no QR friction. Tap once, see a tick, and your receipt appears in your e‑me app. Built for retailers and shoppers who value speed, privacy, and control.

How it works

1) Pay as normal

Customer pays using card or mobile wallet. No change to the merchant’s payment flow.

2) One post‑payment tap

After approval, the customer taps their phone to the terminal (or scans a QR on iOS). A tick confirms identification.

3) Receipt appears in e‑me

The receipt is delivered instantly and stored securely. Customers can search, export, and share when they choose.

Why retailers choose e‑me

✓Faster checkouts: cut email capture and paper waste; reduce queues and errors.
✓Privacy‑first: post‑payment identification preserves anonymity during payment; customers stay in control.
✓Works with your stack: Android POS, iOS fallback via Wallet pass + QR; REST webhooks to your back office.
✓Actionable data: with consent, unify receipts across channels for returns, warranties, and insights.
✓Low lift integration: simple SDKs and clear API; start with one till, scale to all stores.
✓Green by default: eliminate paper receipts and reduce costs.
