A credit cardholder should consider using one of three-dimensional security features for their credit cards. Three-dimensional security can be described as a layered approach to credit card security. There are essentially three domains involved in credit card three-dimensional security: the merchant/acquirer domain, the gateway domain, and the interoperability domain. This article focuses on the merchant/acquirer domain. As mentioned above, there are two parts to this: the merchant account (where the card is issued) and the acquirer account (where the card is deposited into the bank). These are the most important parts in credit card three-dimensional security.
One of the advantages of having your credit card details encrypted with a 3D encryption is that it prevents identity theft. All data passing between the merchant and the acquirer should be protected. If data is intercepted, misuse, or fraud, it could be used to commit fraud against you. This is why banks and credit card companies work so hard to prevent credit card fraud: it costs them money and they have to recoup some of that money from the victims of fraud. Auto-renewal is another benefit of having your credit card details encrypted with a 3D security feature.
You can use three-dimensional encryption and auto-renewal when you use a secured three-way connection such as EDGE, Wi-Fi, or Bluetooth. For instance, when you make a purchase of a gas pedal to go somewhere and instead plug it into your car's cigarette lighter you are making a secure transaction. To ensure that your purchase goes through, you can set up your account to make a connection with an auto-renewal facility. Then when you put your credit card into the key pad, a request will be sent from your device to the EDGE or wireless connection to determine if the transaction should go through, and then it will go through.
There is a third option for secure credit card transactions: the Let parameter. A Let parameter allows you to specify a minimum amount of money that must be placed down before a transaction can go through. A bank will not accept a transaction for this amount unless you have a dollar bill in your hand. A user may set the Let parameter to a figure between one and ten dollars. In addition to letting you restrict the amount of money that you are willing to pay upfront, the Let parameter will also allow you to set the rate at which your credit card charges.
To take advantage of the Let parameter, you need to have a dollar bill on hand. When a user inputs his credit card transaction information and selects a payment method, his transaction will go through even if there is no dollar bill in his hand. If the inputs a payment but has no dollar bill in his possession, his transaction will go through as long as there is someone who is authorized to accept this transaction.
A fourth option for a secure 3D payment is available methods. These methods include the authorization code, which is a PIN-based product that a customer can program into his card. This PIN must be entered before the transaction goes through, so it is important that you provide a secure encryption system to your customers. There is also an option to use the OTP, which is an SMS-based product that you send to your customers when they enter their PIN.
As you can see, there are a lot of security options available for your consumers. However, most of these options only work while you are online, which is why most 3DS consoles do not have the feature built-in. Because transactions are conducted between people who are near to each other, using software to keep an eye on transaction status is the best way to make sure that everything goes smoothly. For example, a midtransaction browser on your console will let you monitor the progress of a transaction as it happens, and will automatically re-transmit the data if the original user's data is not available. These types of features are what you need to get the most out of your Nintendo's 3DS system, so make sure to keep your eyes open for any possible security issues by installing the latest update, or you might find yourself out of luck come the holidays!
