The client has provided us AnywhereCommerce C2X Walker card reader and Live account credentials.
Using the sample app provided we were able to make test payments in the sample app provided in the Github account.
After adding the sdk in our app, I am able to create merchant (by authorizing merchant using create merchant API) and also getting sesstion token.
The merchant created is a static object so all it's data is stored with the Merchant object before closing the app.
Now when I try to make payments I'm getting the following error.
"Unknown device error, please try again"
EVMErrorCode = UNKNOWN_READER_ERROR
Please guide me if there is any issue with my integration that is causing this issue.
Any help would be appreciated.
Thanks in advance.
