I check my bank accounts online almost every day. I check in more often then I use to, but mostly cause I go online to pay business bills and check deposits. In the old days, I mailed checks and I never received direct deposits from clients. Now, I pay virtually all my bills online and receive some payments via wire or direct deposit.
Recently, someone I know had their bank account broken into. Someone was withdrawing funds. He was so paranoid, until he got things switched, that he checked his bank account several times per day. Understandable!
How often do you check your bank accounts online?
