Digital ID World presentation on CardSpace in credit card txns (20070925)
Sid Sidner of ACI Worldwide presented "Online Payments using Information Cards" at the DIDW conference (DIDW2007). This presentation followed from a post "InfoCard and e-Commerce" he made to his blog in December 2006.
He mentioned several enhancements he had requested of Microsoft individuals to be made in future versions of the InfoCard protocols, such as
- the use of the "question mark" symbol in URIs should terminate matching, and
- multiple issuers should be allowed in a WS-SecurityPolicy element.
