What security measures does American Express have in place for business cards?

American Express implements a robust suite of security measures for its business cards to protect users from unauthorized transactions and fraud. One of the fundamental features is the advanced fraud detection system that monitors transactions in real time. This system utilizes sophisticated algorithms to identify any suspicious activity, flagging it for further investigation. If a transaction appears unusual based on the cardholder's spending patterns, the cardholder may be alerted promptly. Additionally, American Express business cardholders benefit from a zero liability policy, which means that they are not held responsible for unauthorized charges made with their card, provided they report them within a specific timeframe. This policy offers an added layer of protection, giving cardholders peace of mind as they conduct their business transactions. To enhance security further, American Express business cards typically come with features such as enhanced chip technology, which provides a more secure method of authorizing transactions when making purchases at merchants that support chip card transactions. Moreover, many American Express cards offer the ability to manage accounts through mobile applications that include security alerts and options for card lock features, allowing users to disable their cards if they suspect any unauthorized use. For further details on specific security features tailored to different cards or account types, cardholders may want to consult the official American Express website or their account documentation. The website typically provides comprehensive information regarding card security measures and may also include contact information for more personalized assistance.
