Black is the noblest color. Black Gold Card - a privileged credit card owned by the world's richest people. In 1999, American Express selected top customers among platinum card holders and issued them a top-notch credit card—the Centurion Card—commonly known as the American Express Black Card. It became a hit after its issuance. It became popular and set off a whirlwind of buying. This little black card is made of titanium alloy and weighs less than 1 ounce, but it's enough to help the cardholder buy anything. According to this newspaper’s understanding, American Express issues invitation letters after evaluating the customer’s net worth, credit situation and consumption status, but the invitation criteria for the Centurion Card have not been announced on its official website. According to the latest cardholder agreement of the credit card, the annual fee for the Centurion Card in the United States is US$2,500 and the application fee is US$7,500. According to foreign media reports, in order to maintain membership status, cardholders are expected to spend at least US$250,000 per year. And whether it's a personal or business version, the American Express Centurion Card is a credit card that charges no interest rates (of course you must pay it back in full each billing period), has no preset spending limit, and has no foreign transaction fees.
