A teller handles customer transactions at a bank branch. They take deposits, cash checks, process withdrawals, accept loan payments, and issue cashier's checks. They are the face of the bank for many customers, especially older ones who prefer in-person service. The job is repetitive, detail-oriented, and surprisingly demanding.

Tellers must balance their cash drawer at the end of every shift. If it is off by more than a few dollars, they may be written up. They must verify signatures, check identification, and watch for counterfeit bills. They must follow anti-money laundering rules, which means filing reports on large cash transactions and suspicious activity. They must also sell. Many banks expect tellers to refer customers to other products, like credit cards or savings accounts.

The role has changed. With mobile banking and ATMs handling most routine transactions, tellers spend more time on complex tasks and customer service. Some banks have replaced tellers with universal bankers who can open accounts, process loans, and handle transactions. Others have automated teller windows entirely. The number of tellers in the United States has declined by about 15 percent since 2010.

The pay is modest, typically $15 to $20 an hour. The hours can be long, and the work can be stressful. But the job offers stable employment, benefits, and a path into other banking roles. Many branch managers and loan officers started as tellers.
