Heres How Credit Card Skimming Works

Do RFID Credit Card Blocking Sleeves Work?

As you slide your credit or debit card into a compromised machine, the card skimmer reads the magnetic strip on your card and stores the card number. Your PIN can be captured, too, if a fake keypad was placed over the real one. Later, a thief scoops up the information and either sells it or uses it himself.

The number of compromised cards at U.S. ATMs and merchants rose 70 percent in 2016, according to FICOs Card Alert Service. But you can learn how to avoid credit card skimmers.

Youre most likely to see these devices at gas pumps, ATMs or metro station ticket kiosks. But if your card leaves your sight at a restaurant or department store, an employee could use a skimmer to get your card info, too.

How To Choose The Right Credit Card For You

The key to choosing wisely when it comes to credit cards is understanding all the costs associated with them. If you were to carry a balance, what would your APR be? Does the card have an annual fee?

Also, consider the cornucopia of rewards credit cards out there and think about what perks would benefit you most. Is it travel miles? Discounts at gas stations? Or simply cash back?

How Card Readers Work

Card readers are an essential component of the modern payment processing system. They have become ubiquitous in recent years, commonly used in retail stores point-of-sale terminals as well as the automated teller machines offered by banks. By using card readers, merchants are able to accept purchases from customers and can greatly increase the speed of transactions.

Todays payment cards contain the cardholders personal information in either a magnetic strip, or a microchip, or both. This information includes the cardholders full name, as well as their account number, card expiration date, and validation code. Modern card readers can quickly decode this information from the card and then pass it on to the other parties in the payment network in order to obtain authorization for the transaction.

For example, the information obtained by the card reader must be passed on to the customers issuing bank, which is the bank through which they obtained their credit card or debit card. The issuing bank is responsible for determining whether the customer has sufficient credit or cash to complete the transaction. At the same time, the issuing bank will also check to see if the card in question has been deemed ineligible for future transactions, such as due to being associated with fraud. Assuming that there are no issues with the cardholders account, the issuing bank will transmit its approval to the POS system, and the transaction will be authorized.

Card Not Present Transactions

Card not present transactions present another set of challenges for the actors in the electronic payment drama.

A CNP transaction occurs whenever the purchasers payment card is not physically present at the merchants point of sale. Common examples include online transactions, wherein the purchaser types the cards digits into a secure field, and over-the-phone transactions, where the purchaser keys in or verbally states its digits. Pay-at-the-pump gas purchases are a hybrid case, because while the card is physically present, there is no human attendant to verify the users identity.

CNP transactions are less secure than in-person and mobile contactless transactions. According to Mobile Transaction, a United Kingdom-based mobile payments provider, 64% of all UK credit and debit card fraud stems from CNP transactions, costing £245.8 million in 2014. Criminals prefer to use stolen cards in CNP transactions because its easier to mask ones identity when one is not face-to-face with a merchant, theres no risk of being asked for identification during the transactions, and the protections afforded by EMV dont apply.

Due to the heightened security risk, merchants are advised to take additional precautions when accepting CNP transactions. There are also some practical differences between CNP and in-person transactions.

Authorization procedures differ for certain types of CNP transactions.

Foreign Cash Advance Fees

The fee for a cash advance outside of Canada is typically higher than it is in Canada. A foreign currency conversion charge may also apply to a foreign cash advance. Like a cash advance in Canada, youll need to pay interest charges from the date you take out the money until you pay back the full amount.

Example: Interest Rate Increase

Say you have a promotional interest rate of 4% for the first 6 months that you have a credit card, which will increase to a standard rate of 19% after the first 6 months. But because you miss your minimum monthly payments during the first 6 months, your interest rate increases to 24%. This would seem like a 20% increase over the promotional interest rate.

Check with your credit card issuer about how much your interest rate will increase if you miss your required monthly minimum payments. This information is usually provided in your credit agreement or information box included in the credit card application.

Federally regulated financial institutions such as banks must notify you before an interest rate increase takes effect.

How To Spot And Avoid Credit Card Skimmers And Shimmers

Small devices called skimmers and the even more insidious shimmers can easily steal your credit and debit card information when you swipe. Here’s how to protect yourself from these rare, but nasty, attacks.

I vividly remember the moment I realized how woefully insecure credit and debit cards are. I watched as someone took an off-the-shelf USB magnetic strip reader and plugged it into a computer, which recognized it as a keyboard. They opened a word processor and swiped the card. A series of numbers dutifully appeared in the text file. That was it: The card’s information had been pilfered.

That same technology has matured and miniaturized. Tiny “skimmers” can be attached to ATMs and payment terminals to skim your data off the card’s magnetic strip . Even smaller “shimmers” are shimmed into card readers to attack the chips on newer cards. Now there’s also a digital version called e-skimming pilfering data from payment websites. Fortunately, there are many ways to protect yourself from these attacks.

How Do Contactless Readers Work

The vast majority of us rely on contactless readers every day, but how does contactless work in the grand scheme of payment processing?

Most card networks now offer contactless cards, including EMV and American Express. If youd like to put two big guns of the payment industry against each other, our Visa vs Mastercard article is a great comparison piece.

To purchase something via contactless payment, customers hold their card within a close radius of the card reader so the card reader can communicate with the small microchip .

The microchip incorporated into the card is capable of emitting short-range radio waves that send the customers card information to the contactless payment machine.

The technology is called radio frequency identification or RFID and is used in a bunch of other products like security tags, smartwatches, security fobs and so on. RFID is also used by Apple Pay, Android Pay and Samsung Pay devices.

The only downside to contactless payments is the risk associated with not having a 4-digit PIN code. If you were to lose your card, there is no way to verify that it is you using the card which is why there is a £45 transaction limit .

How Credit Card Debt Relief Works

Debt settlement will only come to play if you have failed to pay your debt on time on numerous occasions. Your creditor or debt collector will not accept less than you owe them without any valid reason or if they believe that you can still pay the full loan amount as per the initial agreement.

Mobile Wallets And Contactless Payments

What Are RFID

Most consumers today cant remember a time when credit cards werent ubiquitous, but there was indeed a time in the not-too-distant past when paper was more common than plastic.

The payment landscape continues to change, in fact. Though still not as common as traditional credit card payments, mobile contactless payments are increasingly popular and seamless. As smartphones get even better and more merchants see value in contactless acceptance, the move toward mobile payments is likely to accelerate.

Technologically speaking, mobile contactless payment is revolutionary but logistically, its not. Contactless payment occurs within the basic electronic payment framework described in this post, with some important differences that improve transaction security.

Different contactless payment vendors take different approaches to security. The two most widespread are virtual cards and tokenization.

Virtual CardsThe popular Google Wallet contactless payment system, which lets you send and receive payments from your smartphone, uses the virtual card approach. According to , Google Wallet creates a special MasterCard or Discover debit card number for each customer. This number functions as a real card, issued and backed by a real bank, but bears no resemblance to the cardholders actual payment card number.

What Is A Credit Card Reader

A credit or debit card holds vital information on its magnetic strip or microchip . For example, a credit card contains the consumers name, account number, the card expiration date, and the cards validation code, typically found imprinted on the back of the card.

A credit card reader is a device that decodes the personal and financial information contained in the magnetic strip or microchip of a credit or debit card. The card reader reads the credit or debit cards information. It then transmits this information to the payment processor, who communicates digitally with the customers bank or other financial institution, confirming that the funds for the purchase are available. After the payment processor confirms the availability of funds, the merchant receives an approval code, allowing them to complete the sale.

Traditionally, credit card readers were tied to traditional cash registers or, more recently, to in-store point-of-sale systems. However, with the advancement of technology, credit card readers have become more accessible. For example, you can connect a credit card reader with your smartphone, allowing you to take payments on the go.

Using Credit Cards Responsibly

  • 1Build your credit history with regular small purchases. In general, your strategy with your new credit card should be to make small purchases fairly regularly and pay them off immediately. This shows the institution that gave you the card that you can responsibly pay back your credit balances, which in turn boosts your credit history. Having a strong credit history is important it can make it much easier to make important financial transactions in the future, including:
  • Getting a mortgage for a house.
  • Getting a loan for personal expenses.
  • Getting good deals on new credit cards.
  • 2Keep your balance low as possible. It may seem like the best way to build a good credit history is to spend lots of money with your credit card, then pay it all back and repeat this over and over again. In fact, consistently using lots of your available credit is a bad idea and can hurt your credit history. This signals to financial institutions that you have a hard time meeting your expenses with the money that’s ordinarily in your bank account, so you have to rely on credit, which is, of course, someone else’s money.
  • Most financial resources recommend spending no more than 70-75% of your available credit, though less than 30% is usually seen as preferable.XResearch source
  • If you need to dispose of your credit card or any vulnerable credit card information, destroy it first. You can cut a credit card into pieces with ordinary scissors and shred or burn paper documents.

    Are Skimmers Still A Threat

    While researching an update to this article, we reached out to Kaspersky Labs, and company representatives told us something surprising: skimming attacks were on the decline. “Skimming was and still is a rare thing,” said the Kaspersky spokesperson.

    The Kaspersky representative cited EU statistics from the European Association for Secure Transactions as indicative of a larger trend. The EAST reported a record low in skimmer attacks, dropping from 1,496 incidents in April 2020 to 321 incidents in October of the same year. The effects of COVID-19 might have something to do with that drop, but it’s nonetheless dramatic.

    That doesn’t mean skimming has gone away, of course. As recently as January, 2021, a major skimming scam was unearthed in New Jersey. It involved attacks on over 1,000 bank customers, with criminals attempting to make off with over $1.5 million.

    Other Online Security Worries

    If you want to worry about the security of your EMV credit cards, dont worry about thieves using scanners to remotely steal your credit-card information.

    Instead, worry about them accessing your credit-card data from all those online purchases you make.

    Jo Lintzen, vice president of business development with security manufacturer Ultimaco, said that most criminals want to work as little as possible when it comes to pulling off their crimes.

    With computer-chip cards making it more difficult for thieves to steal card information at check-out counters, and with most card providers abandoning the idea of RFID-fueled contactless credit cards, it makes sense that criminals would focus their efforts on the online world, Lintzen said.

    There will be a shift in online fraud simply because it will now be more difficult to commit other types of credit-card fraud, Lintzen said. The bad guys are creative. They will look for other targets, and online credit-card transactions are an obvious target.

    You can protect yourself while shopping online, up to a point.

    First, shop only with retailers you know and trust. Secondly, only use your credit cards at online retailers that run sites that are encrypted.

    A retail site is encrypted if it features an icon at the top of your browser that looks like a padlock or an unbroken key.

    You can also look at the Web address in your browser. If it starts with “https://” and not just “https://”, you know that it is encrypted.
