Of course I overexaggarated. But I did read their own webpages faq and what the thing is supposed to do. And this is the catch. It says what they want to do, what it should do, but not what it can do and what it is. It is wishfull thinking about an ideal service or rather protocol. They try to catch the anonymous payments and while they are at it, the microtransactions as well. Of course , to show their  universal applicability, they include the ability to have bitcoins as well in their wallet. 

And it is a BS concept, because smartphones get lost or broken   and computers get hacked all the time. Electronic cash is not a thing people have trust in.   The guys behind the Taler are Germans, they should remember the Geldkarte.    It was around for like 25 years.     It was cash on a card. Pushed by banks and rather widely accepted.   But the only use those got were verifying age when buying cigarettes at a   dispenser. 

Sure, some anonymity would be nice when giving money to people you do not receive physical goods from. But I need not have that anonymity from the payment processor. They know who I am anyways, because I have to send them the money from real life accounts , like credit card. There is no principal technical barrier from making something like a Steam wallet x-plattform. And regarding micropayments, have a look how the pros do it.  They really exchange your money into virtual tokens that you do your microtransactions with. Usually for in-app purchases, but that is another discussion.  Regardless, such a service across platforms would implement the microtransactions we want.
