# POS Bridge stable
POS Bridge is an Android service that allows allows a point-of-sale application running on an external system (i.e. client) like an iPad or Windows PC to connect to the Poynt terminal over a local network connection (TCP port 55555) using Poynt iOS SDK (opens new window) or Windows SDK (opens new window).
POS Bridge can be downloaded and installed from the the Poynt Store.
When POS Bridge app is launched it starts advertising its IP and port using network service discovery (opens new window). CONNECT MANUALLY button can be used to display terminal's IP address and pairing code if the system connecting to the terminal does not support network service discovery.
Once a pairing request is initiated by the client the POS Bridge will display a confirmation dialog:
The confirmation dialog timeout is set to 30 seconds.
After the pairing request is confirmed the POS Bridge will display the name of the connected client. Pairing can be terminated by tapping on X button.
POS Bridge will remain running in the background and does not need to be open to accept payment requests from the client.
At the moment the terminal can be paired with only one client (POS) using POS Bridge.
