Some tellers specialize in handling foreign currencies or commercial or business accounts.
Before cashing a check, the teller must verify the date, bank name and identity of the person to receive payment, and see that the document is legal tender, that written and numerical amounts agree, and that the account has sufficient funds to cover the check. The teller must carefully count out the cash to avoid errors. Sometimes a customer withdraws money in the form of a cashier's check, which the teller prepares and verifies. When accepting a deposit, the teller checks the accuracy of the deposit slip and processes the transaction. Tellers may use machines to calculate and record transactions and to prepare documents, such as receipts and drafts.
