CONFIDENTIAL © Yoyo Wallet Limited 2017
Yoyo requires access to an outbound internet connection to send messages to the Yoyo server. The data required is small and will not affect your capacity issues.
Where the existing EPOS system already has an internet connection, Yoyo should work without needing to make any changes to your firewall. We request that this gets checked following these steps.
If the tills are not yet connected to internet, please ensure that outbound ports 443 OR 4040 are open.
Connections are secured using these port rules. Servers are tightly grouped by role to ensure only required connections are allowed.
All other connections are prohibited. All connections to the system are protected using SSL/TLS v3.0.
Please see further information regarding security and regulation.
