Hello @shan2

Sorry to hear you are experiencing issues when your customers try to use their cards. 

To be able to better assist here, please provide more details about the issue you are having. 

Is this happening when trying to complete in-person sales or Online Store transactions? 

Are you using our hardware to swipe/tap/insert cards?

These and other details you can provide will help us troubleshoot. 

Thank you!
