More and more people in the US are apt to make purchases in online stores or pay for services in the Internet. In fact, according to BI Intelligence agency, back in 2016 Americans spent about $385 billion while paying online, and by 2020 this figure will reach $632 billion.
The majority of American online shops accepts only cards issued by a US bank. To be precise, the billing address (the address you specify when opening a bank account) of the credit card holder must be US. However, this applies not only to purchases in online shops, but for any kind of service. On the other hand, American card will be accepted when paying in European online stores. So this is the additional benefit feature of the US banking card product.
