A bank teller is a financial professional who works at a bank or credit union. Their main job is to assist customers with various transactions, such as depositing or withdrawing money, cashing checks, and managing accounts. Bank tellers also provide information about bank services and help customers with basic inquiries. In addition to handling cash, bank tellers must ensure the accuracy of transactions and maintain security protocols. They often use computers and other technology to process transactions efficiently. Good customer service skills are essential, as tellers interact with a wide range of customers daily.
