How Can We Help?

EMV processing hangs often

You are here:
< Back


You have been processing through the day and using the EMV terminal and then all of a sudden, nothing happens and you have to key-enter the transaction and you’ve been restarting the BFCSignalRBridge service multiple times a day to keep things working ok.

The root problem is the BFCSignalRBridge service is running an older version of the application and even when installing the latest from the web site, it is still running the old version.


Everything would work normally but then randomly, when loading the page, the system would just freeze/hang. It could be right before a transaction or just after a transaction.

Current users have been able to restart the BFCSignalR Service from the services window or by using the Task Manager and ending the BFCSignalRServiceBridge.exe.
