Run IPC as a Service

IPC may be run as a Windows service when using HostedEVT mode i.e. IPC communicates with POS using IntraMessages and no IPC UI is displayed.

When IPC runs as Windows Service the merchant application is enabled to gracefully start/stop IPC and/or to abort execution of IPC by using appropriate scripted commands.

To enable this option IPC should be configured with options ‘Run IPC as Service’ and ‘Is HostedEVT’ selected in IPC Configuration -> Hosted IPC tab. using appropriate .bat/.sh files.

Note : IPC as a Service is not yet supported for United States geography.


  1. Steps to run IPC as Service**

    1. Run Emboss set up as same as normal IPC Application

    2. Select ‘IPC as a Service’ option present in Hosted IPC tab in YESEFT Configuration.

    3. Select Pinpad.

    4. Go to bin folder,

      • Run installIPCService.bat to install Application Service.
      • Run startIPCService.bat to start IPC Application and check logs yescps.log and wrapper.log (for console logs) in YESEFT\logs folder.
      • Run stopIPCService.bat to exit IPC Application.
      • Run uninstallIPCService.bat to uninstall Application Service.
  2. YESEFT Folder contents:**

    IPC as a Windows service has been enabled through the Yet Another Java Service wrapper i.e. yajsw software.

    The yajsw jars i.e. wrapper and wrapperApp jars are present within in the YESEFT folder

    a) YESEFT/bin Folder

    This folder contains some additional necessary scripts used for running IPC application as service.


    The following Windows bat files are present inside this folder:
