Hello SaivarunreddyM,

I've seen similar kind of requirement in my experience. However, there is a difference in the device. In my requirement I've seen soft telephone. Once user accepts the call there a case is automatically created in Pega. The same suits to your requirement as well.

1) Create a Service REST rule in Pega and get the url. You can look at OOTB Service REST "Cases" to know how to create a case. In this rule, go to methods tab and check "POST", you will find pzGreateCase activity

2) Integrate the url with scanner device. For example, my url is "http://myhost/prweb/api/v1/cases". This URL has to be integrated with scanner software. (Please note that scanner vendor must support this )

Whenever your scanner captures something, it will initiate a request for the above url along with parameters, which automatically (you have to show the captured results at the end of the activity using show-page method or anything which suits your requirement) displayed in the Pega portal web page.

I hope this gives you some idea on how to do. Please feel free to reply your thoughts if any.

Thank you,
