These merchants usually establish a formal cooperative relationship with credit card issuers and can provide a certain degree of shopping protection and customer support. The following are several factors to consider when choosing a merchant:

1. Large retailers and shopping centers: Large chain stores and shopping centers usually cooperate with multiple credit card issuers and provide a variety of payment methods. They are experienced in credit card payment, and their services and safeguards are relatively perfect.

2. Online shopping platforms: Well-known online shopping platforms such as Amazon, Taobao and JD.COM are also good choices for swiping credit cards. These platforms have established cooperative relationships with multiple credit card issuers and provided convenient and fast payment methods.

3. Dining and entertainment places: Restaurants, bars, cinemas and entertainment places usually accept credit card payment. Using credit cards in these places can make it easier for you to track and manage your expenses, and you may enjoy some discounts or rewards.

4. Airlines and hotels: If you travel frequently, it may be a good choice to choose airlines and hotels as credit card consumers. Many credit card issuers have strategic partnerships with airlines and hotels. Paying by credit card can help you accumulate mileage or get other travel discounts.

it should be noted that when choosing a merchant who swipes a credit card, it is necessary to ensure that the merchant has a good reputation and a credit card payment system, and follow relevant laws and regulations and safety measures. In addition, when choosing a credit card, you need to comprehensively consider the cost, interest rate, incentives and security measures of each credit card according to your own consumption habits and needs.
