I stick to cash because I don’t think my bank should know things as sensitive as the full history of my transactions, which may or may not also be sold to others. Also in times like these I would not be surprised if you’d get in trouble for transferring some funds to a dissident’s card, while in reality it was just splitting the bar bill.
When it comes to in-person payment, would Taler be usable without a mobile device? Say, with just a card like normal banking? I would have it much rather coexist with cash anyway.
But yea, sounds like an improvement when it comes to online payments.
