A primer on the workings of a credit card

Credit cards are a boon in these modern times and there is no denying that. A swipe, a touch, a tap, and everything is paid for (yes, you do pay for what you buy, but not until later.) So, what’s the idea behind these swipes? Who is actually paying for the stuff we purchase? Are credit card companies making money every time we use our cards? These are some of the questions that we’re going to try to answer for you.

What is a credit card?

A credit card is a plastic payment card that is designed to provide us with a certain amount of credit. This amount can be used to make purchases. The only criterion is that you have to pay the money back as per the credit card company’s policy. When you pay the money back, the credit is restored to its original limit. In a way, a credit card is like a replenishable loan. You can keep taking the loan as long as you pay the money back within the stipulated time period.

How does a credit card work?

A credit card electronically transfers money from one person’s account to another’s. To do this, there are multiple stakeholders involved, namely the issuer, network, merchant, and user.

When you use your credit card, the merchant’s terminal uses the network to ask the issuer if the card is valid. It then asks whether there is enough credit on it. Depending on this, the transaction is either approved or declined. The money is then transferred from your account to the network and merchant.

How do credit card companies work?

For a credit card to work, there are two backend enterprises: one is the issuer of the card (the credit card company) and the other is the network.

Banks and credit unions are the credit-card issuers. Networks are companies that process credit card transactions. These include companies such as Visa, Mastercard, American Express, and more.

How do credit card companies make money?

One of the key stakeholders in the credit chain is the customer. Without the user, none of the credit card companies would be able to make any money. Below, we enlist three major sources of revenue for credit card companies:

  1. Interest

The customer is charged interest when they default on their payments. Different credit card companies have different rates of interest. This interest is charged on the total amount that has to be paid back to the issuer.

  1. Fees

Fees are essentially charges for using the service provided by the credit card company. They are predominantly divided into annual fees, cash fees, late fees, and balance transfer fees. The annual fee is charged on cards that typically come with high rewards; the cash fee is charged when you use your credit card to withdraw cash from your account; the late fee is charged when the user fails to pay the amount back by the prescribed due date; and the balance transfer fee is an amount charged by the issuer to transfer existing balance from one card to another.

  1. Interchange

While the user pays their dues, even merchants have to pay a certain amount of the money that is received to the issuer. This amount is the processing fee, and it can vary depending on the amount and number of transactions.

Interest and some fees can most definitely be avoided by paying credit card bills on a timely basis.

Learn about these 3 types of hearing loss

Hearing loss, deafness, or impairment is the partial or total inability to hear sounds. People with low to moderate hearing impairment face challenges in understanding what the other person is saying in a noisy environment. Whereas, people with severe deafness cannot hear anything, and rely completely on lip-reading and sign language skills. There are three main types of hearing loss: sensorineural, conductive, and a combination of both. Let’s understand these types in detail and learn about the causes, symptoms, and treatments of each type. Sensorineural hearing loss It’s the most common type of hearing loss. Sensorineural is permanent hearing loss often caused by damage to the tiny hair cells that line the inner ear or the auditory nerve. The damage stops or weakens the transfers of nerve signals to the brain. These signals are essentially the intensity and clarity of sounds. Causes: Aging and exposure to loud noises for a long period of time are the most common cause of the damage. Certain medications and illnesses can also increase risks. It can even be genetic, and pass on to the child in the mother’s womb. Treatment: There is no medical or surgical treatment available to repair the tiny hair cells once they’re damaged.

Simple lifestyle changes that reduce the risk of heart diseases

The heart is the most crucial organ in the body and as the system will cease to function if the heart stops or loses momentum pumping fresh oxygenated blood.

How to distinguish between heartburn and GERD

Heartburn is an unpleasant, burning sensation in the chest that is more common than a lot of individuals realize. Pregnant women, older men, and even young adults experience it frequently. Despite it being such a prevalent experience, not many know that heartburn has actually nothing to do with the heart and everything to do with the stomach and the esophagus. Unsurprisingly enough, heartburn is also used interchangeably with GERD. But, before we get to deciphering heartburn and GERD, let’s understand what acid reflux is. What is acid reflux or GER? Acid reflux occurs when the lower esophageal sphincter or LES becomes weak, allowing the contents of the stomach to travel in the wrong direction, back up the esophagus. Acid reflux is also called GER or gastroesophageal reflux as it involves the stomach and esophagus. This condition can usually be resolved with over-the-counter medication. What is heartburn? Heartburn is a burning or painful sensation that is experienced in the chest. Since the lining of the esophagus is not as strong as the lining of the stomach, the acid from the stomach can cause a burning sensation in the chest. This pain or burning sensation that is heartburn can often be misconstrued for a heart attack.

Arthritis is one of the major and most common health conditions in the country, and its intensity increases with age. Here are some common types of joint conditions that you need to know: Osteoarthritis With almost 10 percent of men and 13 percent of women aged over 60 suffering from osteoarthritis, it is one of the most prevalent joint conditions in the country. Osteoarthritis occurs due to the wear and tear of the cartilages that protect the ends of bones. It commonly affects joints of the spine, hands, hips, and knees. If left untreated, this wear and tear of the cartilage soon leads to bone degeneration, thereby affecting flexibility and range of movement. Treatment for osteoarthritis depends on its severity and the patient’s age. Mild symptoms can be treated through medications, physiotherapy, and changes in lifestyle, whereas moderate to severe cases may require surgical intervention. Spondyloarthritis Spondyloarthritis, also referred to as spondyloarthropathy, is a type of rheumatic disease that causes inflammation in various joints. There are two types of spondyloarthritis—axial spondyloarthritis, which causes inflammation of the joints in the chest, spine, and hip bone, and peripheral spondyloarthritis, which causes inflammation in the fingers, knees, and toes.
