Everybody has already seen a credit / debit card machine. Once the merchant swipes the card into the machine, the account information keyed is passed on to the bank. The bank checks the customer's account for the availability of funds. If the funds are sufficient, the transaction is authorized. Thus in a matter of seconds, the whole transaction process is carried out. The customer is happy as he or she gets instant service and a convenient payment option while the merchant is also satisfied to receive an instant payment.
The Credit card machines come according to the specific need of the merchant. Some Credit card machines are wireless, some come with printer, some without printer. The wireless one is the most expensive but is functionally the best.
As grenada does not have presently an operational payment gateway allowing real time online transactions, the use of the credit card machine is the alternative option. The credit card information of the customer is sent via a secure system (SSL / https) to the merchant who then enters it manually into his ctredit/debit card machine to finalize the payment.
