The purpose of the credit check is to establish the creditworthiness of the customer. Only
customer transactions that meet the organization’s credit standards are valid and should
be processed further. In batch systems with manual credit authorization procedures, the
credit department (or credit manager) is responsible for implementing the firm’s credit
policies. In POS systems, the authorization process involves validating credit card
charges and establishing that the customer is the valid user of the card. After receiving
online approval from the credit card company, the clerk should match the customer’s
signature on the sales voucher with the one on the credit card.
