Many people already prefer to pay through credit cards. Out of the total transactions that an average retailer is likely to process, only 5% will be paid for by cash. The convenience of credit card processing is undeniable and the opportunities for it are endless. However some equipment that traditional credit card processing merchants lease out to retailers can be too bulky, too expensive, or lack portability to be taken to places such as trade fairs, conventions, church sales, and any other places where the application of credit card processing would become truly practical. When you think about it, customer reliance on credit cards has evolved to a point where the only transactions that you would ever pay for with cash are at small specialty stores. However finding a merchant that will process your credit card transactions for you can be very challenging, since many of them will lure you in with promotional rates that hardly any of the processed credit card transactions will qualify for.
