Payment security

epay-gateway is designed so that merchants never see your PIN or card details.

No card or PIN storage​

  • Card data is entered on the Djomy-hosted portal (PCI-DSS compliant) and never transits through the merchant's server.
  • Mobile-money PINs are entered on your phone, not on the counter.

HTTPS everywhere​

All traffic between your browser, the counter, and the payment provider is encrypted with TLS. If your browser shows a lock icon, you're on a real epay-gateway instance.

Signed notifications​

When your payment succeeds, the counter notifies the merchant via a signed HTTP request. The merchant verifies an HMAC signature before trusting the notification — meaning a third party cannot forge a "paid" status for a transaction.

Checksum & CSRF protection​

Every payment form includes a checksum that the counter verifies before contacting the provider. This blocks tampered or replayed requests.

What epay-gateway stores​

  • Your phone number (for mobile money), hashed with the transaction
  • The amount, currency, and a provider reference
  • Your name/email if the merchant collects them at checkout

epay-gateway does not store your OTP, PIN, card number, or CVV.
