Q. American Express? Do my customers carry it?
A. American Express is increasingly becoming a popular Card with consumers, small businesses and corporations. With a strong loyalty program, and a high quality customer base, American Express Cardmembers are high spenders, average spend is 129% higher than that of Non American Express Card holders in Hong Kong1. When you put this together with our strong Corporate Card presence and our traditional Consumer Cards, it means there・s a more diverse and larger range of people who carry our Cards.

Q. My competitors don・t accept it. Why should I?
A. American Express® Cardmembers have been proven to have higher transaction values and spend 129% more than average spend of Non-American Express cardholders. This is supported by a strong loyalty program. American Express offers an opportunity for Merchants to attract and retain great customers. What・s more, American Express Cardmembers actively seek out accepting Merchants, which gives your business the chance to stand out from the rest.

Q. How quickly am I paid for my American Express transactions?
A. This will vary, with some Merchants receiving in two business days payments. However, please note this is dependent on your agreed payment plan.

Q. Why do you pay net? Other Card issuers don・t.
A. Net payments means we simply pay for the American Express charges, less the amount of the Merchant fee. We find this is a simpler & easier way of doing business which means we are not regularly deducting fees from your bank account. We provide online or paper-based reporting which makes reconciliation and reporting easy for your business.

Q. How will you help me attract American Express Cardmembers?
A. American Express Cardmembers are great customers who actively seek out accepting Merchants. There is no better advertising for these customers than placing the American Express decal or other
Point of Purchase (POP) materials at your location. In addition, we offer a variety of products and services to help you attract more Cardmembers including, in some cases, marketing support programs. If you want to know more, please contact us on 2277 2277 (Monday to Friday, 9:00am-6:30pm) (except public holidays).

Q. What is a dispute?
A. Occasionally, a Cardmember contacts American Express to query a charge, either because they don・t recognise it or require additional information about it. Usually, this occurs within 60 days of the Cardmember receiving their statement. This is known as a .dispute・.

Q. What is a Chargeback?
A. When a Cardmember disputes a charge, we check the details of the transaction with the Merchant. If there・s reason to uphold the dispute, we credit the Cardmember・s account, and debit the Merchant・s account with the transaction amount. This is known as a .Chargeback・.

Q. Would I be notified of a dispute or Chargeback?
A. If a Cardmember questions a charge and the information we hold is insufficient to resolve the issue, we may contact you for further information. We・ll send you a .Request for Information Letter・, outlining the reason for the dispute and specifying the documents we require from you. Please ensure that you respond fully by the reply-by date indicated on the letter.

In certain circumstances, we initiate a Chargeback without sending a 'Request for Information letter'. An example of this is with Merchants who receive a lot of disputes, or conduct transactions in what we consider to be risky business environments.

Anytime that an enquiry results in a Chargeback to your account, we will notify you accordingly.

Q. What is fraud, and how does it affect me?
A. Fraud comes in many forms, like stolen and counterfeit Cards, for example. It・s likely you・ll have to deal with attempted fraud at some point, so it・s important that you recognise the telltale signs to avoid fraudulent transactions. If you・re slow to react, it can result in loss of goods and revenue through Chargebacks.

Q. How can I avoid fraudulent transactions?
A. We take the security of your business very seriously, that is why we provide guidelines to help you avoid fraudulent activity, whichever type of transaction you are dealing with.

Some ways to help detect fraud include:

  • Checking that the Card has not expired, and has not been altered or damaged
  • Carefully comparing the customer・s signature on the receipt, with the signature on the Card
  • Only sending merchandise to the billing address on the Card, and obtaining signed proof of delivery
  • Making sure your Internet checkout is secure, with industry-standard encryption


Q. What is the Data Security Operating Policy?
A. It・s an American Express policy with which all Merchants, Processors, and Service Providers that store, process or transmit American Express® Cardmembers・ information must comply. This policy has been strengthened to reflect current business conditions, provides additional requirements to help safeguard Cardmembers・ information and conforms with the Payment Card Industry Data Security Standard (PCI Standard). The PCI Data Security Standard sets out a common set of technical requirements for safeguarding sensitive payment data which are applicable across the industry.

Q. Who does the Data Security Operating Policy apply to?
A. It applies to all entities (Merchants and Service Providers) who process, store or transmit Cardmembers・ information. Its requirements apply to all equipment, systems and networks on which American Express Cardmembers・ information is processed, stored or transmitted.

Q. Why is the Data Security Operating Policy important to my business?
A. Compromised data can have a negative impact on your business, other Merchants and Card issuers. Even one incident can severely damage a company's reputation and its ability to conduct business effectively. Addressing this threat by implementing security operating procedures can make your customers feel more secure and enhance the reputation of your business.

Q. Why should my business comply with Data Security Operating Policy?
A. The Data Security Operating Policy is a sound business practice and a requirement of American Express. By accepting American Express ® Cards, you agree to be bound to terms and conditions of our Card Acceptance Agreement, which includes data security requirements and mandates compliance with American Express policies and procedures.

Q. Does the Data Security Operating Policy still apply to me if I do not store Cardmembers・ information?
A. Yes, the policy still applies to any of your equipment, systems, and networks that transmit or process Cardmembers・ information.

Q. Can a Merchant or Service Provider be considered compliant if it has outstanding non-compliance issues?
A. We encourage Merchants and Service Providers to complete an initial review, develop a remediation plan, complete items on the remediation plan, and revalidate compliance of those outstanding items. This plan can be submitted to American Express for review until full compliance can be achieved. If American Express accepts the plan, at its sole discretion, it can choose not to impose the non-validation fees for a Merchant's failure to provide the documentation validating its compliance with the PCI Data Security Standard. A Merchant may still remain liable for fraud as a result of a security compromise.

Q. How does the Data Security Operating Policy compare to the PCI Data Security Standard?
A. The PCI Data Security Standard is the technical foundation for the Data Security Operating Policy, allowing Merchants and Service Providers to comply with one set of data security technical standards. The Data Security Operating Policy defines the levels, requirements and validation deadline for American Express.

Q. I've been contacted by a company called Trustwave on behalf of American Express. I don't know who this Trustwave company is, and this sounds like a phishing scam. How do I know this isn't a scam?
A. American Express has retained Trustwave to help us administer our Data Security Compliance Program. Trustwave is a leading provider of information security and compliance management solutions to Merchants and Service Providers. We are glad you're checking up on this - we can assure you that this company is reputable and will adhere to all American Express privacy principles.
