When you make purchases online, be sure that the card you use has a back and a front side (and sometimes both!). If the site does not have this information, do not proceed with your transaction. The credit card you are using could be issued without a back or front side and if you make a purchase online you are subject to fraud. This is why it is important to protect yourself when making a purchase online.
If you have an account on the merchant account of a business and you make a purchase on their website and the card number is left out by them, you could end up losing your money. If you have the card number, check with the merchant company to see if they have a back or a front side. You might be able to get it from the back side, although most businesses will have both. Sometimes there are differences in the front and back side that might not be clear to the customer.
If you can't find your card on the front side, the merchant may have both sides, but they are not connected. When you make your purchase, make sure that you enter your card number in the proper place. If you use the back side, then you can have either side printed on the back. If you have the front side, then you should only print one side.
A credit card will usually have an authorization number on the front side. Make sure to write down that number and always keep it safe. Most credit card companies will require you to provide that card number at the point of sale. If you are ordering items online, the merchant will usually include an authorization number with the item that you have ordered. However, it is wise to call and request that they give you the card number so that you can make the necessary payment.
Some merchants do not print the back side and that means that they will not be able to accept the credit card. If you make your order online, be aware that your credit card will only work online and not when you have it in your hands. Some merchants do not print either side because they think that the customer may lose it. Therefore, they don't want to offer it.
If you are unable to print the card, you should call the merchant to see if they would like you to return the item if you have to. Or, if you are in the process of making a purchase, they will ask you to return the item. They want to make sure that you really are the owner of the card. You could have had it stolen and they would like to check.
