There are plenty of institutions that work with the software, Internet option or any terminal of your choice. Though this sounds easy there could be a few problems like processing companies that are below the standard, overcharges, frozen funds, middleman surcharges. The right choice of merchant services can eliminate these problems to a certain extent. Application gee will be charged for almost all Merchant accounts and in case there is no fee charged, probably the difference will be compensated with sale of equipment or software or charging for transactions.

The processor cross verifies the validity of the card and its network like Master Card or Visa and confirmation of the fund availability. In case the transaction is approved, the processor is given a code for authorization or the code is given to Secure Payment Gateway by the processor. The Payment Gateway then converts the authorization into an encryption and transmits to the Merchant web server that then completes the order, The web server of the Merchant sends a confirmation to the customer’s browser. The due amount is then transferred from the bank of cardholder to the processing bank of the Merchant.
