The first financial service offered by American Express was a money order, which started to compete with the money order service offered by the US Post Office. Money orders were one of the most widely used ways to send payment at the time, sending a certificate through the post to detail how much that person was owed in cash.
Later on, AMEX would increase the number of financial services they offered when they created the concept of the American Express Travelers Cheque in 1891. This allowed people to use credit to make purchases without needing to carry around large sums of money.
Today, American Express is best known for offering the AMEX credit card, which is accepted by a wide number of businesses all over the world. Included in those businesses areUSA online casinos, which allow users to make deposits and withdrawals using their cards. An AMEX casino is any online casino that accepts payments made using American Express.
