Most betting websites bearing the Amex logo are fully licensed to operate in the online gaming business. Such sites are likely to be owned by well-known parent companies and monitored by online betting watchdogs.
American Express doesn't want to get involved in transactions with unscrupulous businesses, which also protects bettors.
The deposit process for non-American Amex bettors is fairly straightforward, as it follows the normal deposit process for most betting sites.
There may be fees and limits based on the financial institution or the betting site involved, so it's best for potential bettors to do some homework before depositing with Amex. Betting sites usually offer first deposit bonuses, so fees will feel like offset costs.
Some laws may make it difficult for Americans to deposit funds to betting sites through American Express. To circumvent this, bettors who use American Express need to find a 'middleman,' so to speak, like e-wallets such as Neteller or MyPaylinQ. An Amex card can be used to fund these e-wallets, which in turn can be used to fund online betting wallets.
While using an intermediary might seem like a hassle, it can actually be beneficial for bettors as it can be an added security layer.
