What is a payment gateway related to credit card processing?

To put it simply, a payment gateway is the internet's version of a credit card terminal (the machine you swipe your card through in store). A payment gateway is much more than just a credit card machine. It offers the ability to securely process payments in a various amount of ways. It also offers merchants the ability to store credit card information in a PCI compliant environment. The payment gateway assists a credit card transaction by passing through the cardholder data in an encrypted format to the processor platform. A payment gateway can be customized and setup through any retail, restaurant or website shopping cart software. There are a variety of ways a payment gateway is used to process credit card payments but the main function of the gateway is to secure, transmit and transfer the data to a platform for settlement.


Do you need a credit card to get free apps for the Kindle fire?

Why chip more secure than magnetic strip on credit cards?

The chip contains a tiny microprocessor programmed with a unique encryption key different from all other chips. This key cannot be copied as it cannot be read out of the chip, it is only used within the chip, During the process of authorizing the transaction this microprocessor is interrogated and generates a transaction code using that key that uniquely identifies both the transaction and the card used. When the sales terminal sends that transaction code to the bank, the bank's computer can verify that the correct card was actually used. This cannot be verified using the magnetic stripe as it can potentially be copied to any card.


What is a database required field?

It is a field in a database that cannot be left empty when data is being entered. This is because it stores critical information. For example, if you are buying something online, then you need to have a credit card number, so that you can make your purchase. So when storing your details, it is essential that a credit card number is entered. Without it, a transaction cannot happen. So it would be a required field for that database. Some other fields can be left empty if you want, as they are not required fields.

How electromagnets are useful when data is transferred onto a credit card?

Electromagnets are used to encode information onto a credit card's magnetic stripe. Data is written onto the magnetic stripe by changing the magnetization of tiny magnetic particles embedded in the stripe using an electromagnet. This process allows the credit card to store and transfer information when swiped through a card reader.


Why do credit cards have magnetic strips on them?

The magnetic strips on credit cards store important account information, such as card number and expiration date. When a card is swiped at a store, the information is read by a card reader to authenticate the transaction. This allows for quick and efficient processing of payments.
