Often, the duties of tellers begin before the bank opens and end after the bank closes. Tellers use this cash for payments during the day and are responsible for its safe and accurate handling. After banking hours, tellers count cash on hand, list the currency-received tickets on a balance sheet, and balance the day's accounts. They sort checks and deposit slips. Tellers also spend time learning about the bank's products and services and changes in the bank's procedures.
Some tellers spend time refreshing and upgrading their skills.
Tellers may process numerous mail transactions. They may also participate in the marketing of the machines encouraging more people to utilize their services. ATM servicers and clerks may work for depository institutions like banks and credit unions or firms in the business service sector providing ATM machines to outlets like grocery stores and department stores. Head tellers are responsible for the teller line. Their duties include preparing work schedules, accessing the vault, ensuring the correct cash balance in the vault, and taking responsibility for shipments of cash to and from the Federal Reserve.
