cus close to signing one of the last banks

Once CUS signs on one of the last two remaining banks then full deployment of the 500 machines will take place and that's just to begin with. I suspect the major bank that will sign on is ANZ and CUS will do a branding deal with them - free trans for thier cardholders for a monthly branding fee.
The last bank not signed on won't be able to afford not to sign on.
