Triple DES isn't a compliance issue from the meetings I have been in and heard. What I do know is that it is required and few are doing it.
ADA rules were approved by committee but not yet finalized by DOJ. There should be 12 to 18 months to comply. What I don't believe is yet known, is whether or not existing machines will be grandfathered. The biggest change is the requirement for audible communication of the key screens. But there will be connection sockets where (bank issued?) headphones can be plugged in.
You'll find more info, albeit limited,
here and a good primer
here.
