Just a small thought!!!, page-7

It's not that simple though. This is where to many posters here fall down - they get caught up in hype but the question I asked is HOW a company that issues plastic cards incorporates this technology. You say "wooh! yeah! MasterCard!" but there doesn't seem to be any thought about HOW MasterCard could use it.

When I hand over my MasterCard to make a payment, how does WBT come into play?

When I enter my MasterCard details into an online service, how does WBT come into play?

Suppose tomorrow MasterCard came to you and said "yes, we are interested, tell us how it will integrate with us". What do you say?
