Frequently Asked Questions

Everything you need to know about Relay.

What payment terminals are supported?

Relay currently supports PAX payment terminals and is actively expanding to support additional terminal types. Check our documentation for the latest compatibility list.

How do I connect my terminal to Relay?

After creating an account, you'll receive a pairing code. Install the Relay desktop client on the computer connected to your terminal, enter the pairing code, and your device will be connected to the cloud instantly.

Is there a transaction limit?

No. Each device subscription includes unlimited transactions. You only pay the flat $5/month per device regardless of transaction volume.

What if I need help integrating?

We provide comprehensive API documentation with code examples. If you need additional support, our team is available via email to help with your integration.

Can I test before going live?

Absolutely! We offer a free 30-day trial with no credit card required. You can test the full functionality with your terminals before committing.

How secure is Relay?

Security is our top priority. All connections are encrypted, API keys are required for authentication, and we maintain comprehensive audit logs. Relay acts as a bridge to your terminal - we never store or process card data.

What happens if my internet connection drops?

The Relay client includes automatic reconnection logic. When your connection is restored, devices automatically reconnect to the cloud. Ongoing transactions are protected with timeout handling.

Can I manage multiple locations?

Yes! A single account can manage unlimited devices across multiple locations. Each device is individually tracked and billed at $5/month.
