As far as I can tell from the Amazon Webmaster Central, Amazon has yet to issue an official Amazon Visa credit card login. If they do, it will most likely be in a version that is limited to the United States. If you happen to reside outside of the U.S., don't despair; you still have other methods of securing a card. In this article I will briefly discuss one of them.
The first method that I will mention involves signing up for a bank account with a U.S. financial institution such as Bank of America or Chase. These banks generally issue credit cards with MasterCard or Visa logos. However, they do not make them exclusively for consumers who reside in the U.S. As you might imagine, individuals who are non-residents of the U.S. will find this method a bit complicated. In order to obtain a non-residential Amex card, the individual must apply for an AMEX card with their bank. This is a somewhat long and involved process and I would highly recommend seeking out alternative means of procuring your card before diving into this process.
Another alternative, which also involves applying with a bank, is to apply online for a non-residential Amex card. Many Web sites on the Internet offer non-residential Visa and MasterCard credit cards. You usually have to contact these companies directly in order to secure one of these cards, but the process is usually quite straightforward. The major drawback with this method is that many Web sites will only issue the card to people with a U.S. billing address. If you happen to reside outside of the U.S., this method may not be for you.
A third method that is effective but slightly more complicated is to contact the Visa and MasterCard companies themselves. By doing this, you can often get additional discounts. Be careful, though, as many companies will try to charge you an arm and a leg in order to secure your card. It is important to make sure you read all the fine print in these types of transactions.
The last method is to look at prepaid Visa and MasterCard debit cards. These cards are readily available at most drug stores and also through many other outlets such as convenience stores. They're fairly new and still relatively expensive compared to standard Visa and MasterCard cards, but they are very convenient. They don't carry much weight like credit cards, so carrying a large amount of cash is not a problem. . . . . . . Like Amex cards, you usually must apply for an Amazon Visa credit card with your bank.
There are dozens of other methods available that vary in the number of hoops you need to jump through to qualify, but the three listed above are the most common. Which one you choose will depend on your own needs and preferences. Just make sure to look over all the terms and conditions before you apply for any credit card.
