[Taler] I want to show the use of the Merchant

[Jürgen Beger]

Hi,

next week I want to show some friends some usecases of Taler.
Yesterday I have got a new Version of andoid Merchant Nightly. That is fine.
Some time ago it worked with some drinks only to show...
Today I wanted to use with "KUDOS"
The configuration showes me: 
https://docs.taler.net/_static/sample-pos-config.json
But I do not know the user and the password. If I try my Demobank login, 
the app says "app to old, please upgrade".

Can you help me with an example only to show.

Thanks very much.
