Unless the other person deposits cash into your account then it is possible to reverse the transaction. This is true for all banking transactions. Period.
If you spend some time reading comments above, you should know CASH deposit is reversible for BoA.
No they are not. The person who posted that is likely spreading FUD. The only real possibility to do this is to convince the teller to give the account "intimidate" availability for a check deposit so it would look like a cash deposit on online banking, but it would really not be a cash deposit.
The above is FUD. I had two cash deposits reversed with BoA and they happened several weeks after the deposits were made. It's now 18 months later, and I've still not managed to recover the funds that were reversed. The Bank of America is suggesting I sue them.
