Abagnale was very smart. After a while, he taught himself to forge check. Then he deposited these fake checks. One day, he was filling out a deposit slip at a bank and he got a new idea. He took a few of the deposit slips home. He types hid own account number on the forms. Then he took them back to the bank, and he put them with the other deposit slips for customers to use. When customer used the deposit slips, their money went into Abagnale’s account.
