Thanks in advance !!
Read,
Perhaps if you phrased your question a little better you might get more responses. I can tell you how it works from the side of a merchant.
Your customer comes to you (in your physical store or online store) and picks out an item to buy. At the checkout stage the customer gets to choose payment options. If the customer chooses a credit card (Visa and Mastercard are the most used... followed by AmericanExpress) they either give you the card to run though the system provided by your bank or in the case of an online store, they input the account number and safety code (on the back of the card), their billing address, and confirm the amount of the purchase. Once confirmation is done (either by physicall signing the slip, or by confirming the cost) the customer has bought the item. If in a physical store they walk away with the product... if an online store you send the product to them within 24 business hours.
Then comes the part that all merchants hate. The bank or payment processing company takes a hefty little commission on all sales made with a credit card. Total mine comes to 4.19% (with the hosting company and payment processing company each taking their share of each sale). Which means that the percentage that the cerdit card companies take from me hits my profit margin pretty significantly, when they are already pretty slim to begin with (on the retail side). This is why many merchants will provide a discount to customers who pay in cash or with any kind of verified funds.
So, how do you come to accept cards??? Go to your bank and apply for a merchant account with credit card processing capability. I would shop around and see what the best option is for you.
This seems like a relatively simple answer I've given you... but I know that credit cards are not common in China yet, so many companies may not know how they work. If you need further clarification please don't hesitate to ask.
