Thanks to advances in technology, we no longer have to bring that much cash around on hand with us to buy the things we need and want. The most we need to make room in our wallets and purses for are some plastic cards, or better yet, none at all, if we already have our smartphones with us. And with it just a few more months until the holiday season—where there will obviously be a lot of money changing hands—we’re running a series of articles that tackle each modern payment system currently in use right now. What they are, how they work, and what their pros and cons are.
But before we can get to those newer payment systems, let’s look at one of the oldest electronic payment systems—traditional credit cards. This’ll not only help us understand more of the processes involved in such a system, but also the advantages and the disadvantages that come with them.
First issued in 1966 by Mastercard in the US, the common credit card payment system is a type of electronic payment system that involves the use of a plastic card with a magnetic stripe (or more recently, a chip) that retains information of the cardholder’s credit account made with a bank or other financial institution. The cardholder uses the card to pay for products and services in lieu of cash, and the transactions are logged by the bank as debt to be paid off at a predetermined time.
To fully explain how credit card systems work, we need to explain the relationships between the parties involved in this payment system:
Here's the typical process that takes place after a credit card is swiped:
All of this happens in a matter of seconds, and thanks to breakthroughs in online technology it is a very reliable payment process that is easily available nearly everywhere in the world.
One of the key advantages of using a credit card is that consumers can defer paying for their purchases at a later time. This is especially convenient when a consumer finds themselves without cash at the moment of purchasing. There’s also the fact that many banks allow cardholders to pay their incurred credit card debt in installments or increments.
It's also widely accepted globally, so a consumer isn’t completely out of luck if for some reason they are left with only their credit card in a foreign country, provided they do accept their brand of card.
Since the boom of e-commerce, credit cards have been the target of many cybercriminals who have designed many malware and phishing schemes to steal banking credentials. But credit cards also has its share of offline threats with the proliferation of card cloners—retail PoS devices that have been tampered or altered to retain the information of cards that have been used on them. The simplicity of the traditional magnetic stripe card has made it easy for criminals to use these methods and devices to collect that information for their own gain—such as the use of the stolen credit card information to pay for their own purchases, i.e. credit card fraud.
PoS RAM scrapers are malware designed to do the same exact thing as card cloners, but without the need for a device or physical access to the machine. The malware infects retail PoS devices and sends the information remotely to cybercriminals.
Finally, a cardholder’s credit card being stolen or lost can also lead to unauthorized charges, but thankfully credit card companies have developed policies to protect their customers from such unfortunate incidents. At worst, a consumer will only need to fill out forms to declare that their cards have been used without their permission.
The numerous threats that have preyed on the traditional credit card payment system, coupled with new technology, has led to the development of different payment processing technologies that not only allow for more convenient transactions, but also ones that are more secured.
