A call shop is a business, where users are provided with on-site access to telephones for making long distance call to their home country or any other destination. The payment method can be either prepaid or post-paid, depending upon the requirement of the customers.
In case of prepaid, customer will deposit a certain amount of money with the call shop operator, who then activates a booth for the customer for making calls. Until the amount deposited is finished, the customer can continue making the call. The call records of the customer will be maintained by the billing system and invoice can also be generated. In post-paid system, the invoice is generated and the customer pays after making the calls.
