Taler is a new electronic online payment system that provides
anonymity for customers. Here, {\em anonymous} simply means that the
payment system does not require any personal information from the
payment system does not involve any personal information from the
customer, and that different transactions by the same customer are
unlinkable. For strong anonymity, Taler usually needs to be used in
combination with existing techniques (such as~\cite{apod}) to avoid

The facts that the user does not need to authenticate, and that the merchant
thus never learns sensitive personal information about the customer,
improves usability and security: the payment process is simplified, the
merchant's security requirements are dramatically reduced and the customer's
risk of identity theft does not accumulate with every (micro-)payment.
