I'd never heard of Laser until now. It seems ultimately the issuers just wanted to take more per transaction, hence switching away from the Laser scheme. The Wiki article I read on Laser said it as initially set up as a non-profit and managed by the biggest issuing bank. I guess it's no surprise they moved towards a payment scheme where they can take more of the action, for better or for worse.
Yes, thats probably it. The issuing banks saw an opportunity to make more profits by switching. All the banks here are broke since the property bubble popped and they are desperately trying to find new revenue streams. In addition to the 3% most banks are now starting to charge 0.20 per card swipe, to the purchaser, as well!
I guess what's more surprising is that Merchants weren't more up-in-arms about the higher fees.
Merchants were complaining but then they just accepted it because theres nothing they can do.
The world needs bitcoin so badly.
