Bank of America ATMS have had the envelope free deposits for like a year now, sounds like the new Wells Fargo ones are pretty similar. I've actually found them quite an annoying experience. It takes practically twice as long because there is more steps...telling the machine what kind of deposit (cash or check) and verifying the amount and what kind of receipt do you want. It also is very unreliable in being able to read the check amounts. If you have more than one thing to deposit then its even longer. I'm hoping it gets better as the they move forward!
