Does any online payment system (something like PayPal or the web site of a banking institution) make use of OpenID?

This question appears to be off-topic. The users who voted to close gave this specific reason:

OpenID consists of three people:
- You, the end user.
- An OpenID provider, which can tell other people if someone is you or not (authentication).
- The relying party, which will confirm your identity by contacting the provider above.
Normally, a bank wants to perform the authentication and rely on that themselves. OpenID splits it into the parts 2 & 3 above. Paypal has joined openID, but they don't appear to support what you want. They want merchants to be the relying party, and want to continue hosting authentication themselves. From a security standpoint, this is probably the best, but it does cut the promise of federated identity at the knees.
