Transport

Reliable payment solutions built for transport — from onboard food and drink sales on planes, trains and buses, to ticketing at the point of travel. Offline transaction processing ensures payments go through even in areas with little to no connectivity, so your operations never skip a beat. Built-in fraud prevention, including automatic blocking on hard declines, protects every transaction without adding friction for genuine passengers.

Unattended

Unattended payment points have no staff on hand— G8 is built for that gap. It handles incremental authorisation and instant fund reversal automatically, so customers only ever pay for what they use, whether that's an EV charge, a parking session, or any self-service machine.  A RESTful API makes integration fast for any hardware setup, while support for all major cards, Apple Pay and Google Pay along with multi-currency support means no customer is turned away. G8 scales from a single site to a full multi-country estate on one platform.

G8 Transaction

Lost signal? Keep selling. G8 securely captures the card payment on the device, so your queue keeps moving even with no connection.

Central Location

Each transaction is encrypted and stored on the device, ready to be sent to a central location as soon as a connection is available.

Transaction Processing

The moment the device reconnects, it automatically starts uploading every stored transaction. No manual steps and nothing for your team to do.

Stored transactions are sent securely to your central location in one batch, where they are checked against your BIN and PAN block lists.

Transaction Settled

Back online, G8 carries on as normal, taking payments in real time while any remaining offline transactions finish syncing.

Transactions are processed, sent for authorisation and once approved settled to your account with everything visible in one place.

Fraud Prevention

PAN & BIN blocking, incremental Authorisation. These features are designed to protect revenue, not just process it. Failed payments do not mean lost customers. G8 automatically retries declined transactions until they succeed, enabling you to recover revenue you’d otherwise lose.

Keep Payments Secure

Compliance and security you can trust, backed by industry leading certifications.

PCI DSS Compliance

PCI DSS compliance is essential for any organisation handling card payments. 

  • Protects sensitive cardholder data.
  • Reduces the risk of fraud and data breaches.
  • Confidence to trade securely.
Point to Point Encryption

Encrypts the cardholder's data the instant the card is presented. Your system never sees unencrypted card data, dramatically reducing your compliance burden.

  • Cardholder data is encrypted immediately at the point of card entry
  • Drastically shrinks the scope for a breach of your system.
Secure Key Injection

Lorem ipsum dolor sit amet consectetur adipiscing elit at exercitation ex est optio ut eligendi aliqua.

  • Provides end-to-end assurance - securely injecting keys and managing your payment devices throughout their lifecycle.
