When Shouldn’t Use Your Credit Card for Payment: Top 10

Credit cards might be convenient and reliable, but here are some scenarios where swiping or entering your digits could be dangerous.

We don’t even think about swiping our credit cards these days since it is so common. But, more technology can come with more problems. There is so much to learn when it comes to saving money such as following the habits of debt-free people, learning which bills you shouldn’t put on autopay, and watching out for these Venmo scams. But for now, we’re just going to start with the basics. Here are a few times when you should think twice before whipping out the magic card.

  1. When a website address does not begin with “HTTPS”
    If you don’t see these five letters in the address bar of the website you are trying to make a payment on, it means the site is not secure. “HTTPS is a protocol for secure communication over a computer network which is widely used on the Internet,” explains Robert McKee, lawyer and certified international privacy professional. “Its main motivation is authentication of the visited website and protection of the privacy and integrity of the exchanged data.” If the site does not include an “s” in this beginning part of the URL, opt out of the online purchase, and try using a third-party payment system like PayPal instead. These sites act as another barrier between an organization and your credit information. Make sure you read up on these common Amazon scams, so you can avoid them at all costs.
  2. When you’re responding to an email
    It is better to provide your credit card to someone over the phone (only when you have initiated the call—more on that later) or even via text message than it is to respond with your credit card number in an email. “There is a technique called ‘phishing’ or ‘spear phishing,’ and it involves emails that are designed to extract your credit card number for an unauthorized purchase,” warns Stephen Lesavich, PhD, JD, attorney, credit card expert, and best-selling author. Before clicking on any link, look for phishing clues like spelling mistakes, strange use of English, and logos that look off. Watch out for these Facebook marketplace scams next time you go shopping.
  3. When charity fundraisers approach you on the street
    Quite often, and mostly in big cities, you’ll see charity fundraisers walking the streets in an attempt to collect donations in the form of money for a variety of causes—the environment, child welfare, and pet care, to name just a few. They might only ask to take your name down so they can contact you at a later date, but if they ask you for your credit card, beware. “These causes are known to target people’s emotions to get them to donate,” warns Lesavich. “Although legitimate in some cases, they could instead be scams to charge your credit card and get your credit card information.” If you want to contribute to these causes, a safer bet is to visit their website, check that it’s secure, and then donate from there. Learn about these hidden fees you had no idea you were paying.
  4. When speaking to anyone over the phone
    Try to avoid giving your credit card information over the phone for the simple reason that you don’t know where it will go once you hang up. You also don’t know who’s listening in on the call—whether it’s people around you, someone else on the line, or even the person on the other end of the phone who’s taking down your digits. “One of the most common examples of card information being given over the phone is through delivery food purchases,” says Jeremy Brant, VP of Information Technology for Florida Capital Bank. “In situations like these or other instances where a vendor is asking for card information over the phone, order the service online or pay cash in person.” With delivery food, should the location not have its website (or the website is not secure), third-party smartphone apps like Seamless or GrubHub can fill in the gap.
  5. When an online merchant has no reviews or previous listings
    If you’re considering buying from a merchant on any type of marketplace—from eBay to Etsy—look them up online. If you Google them and there’s only one listing for the merchant, with no online reviews, no past experiences from other customers, and no social media accounts, you should think twice about handing over your card. “The Internet has given consumers a much more effective way to gauge the reputation of the companies we do business with, so use it,” suggests Adam Jusko, founder and CEO of creditcardcatalog.com, a card comparison and news site. Along these same lines, look for contact information on the websites you buy from, including address and phone number if you’re unfamiliar with the merchant.
  6. When you’re making a purchase you can’t afford
    This sounds like a no-brainer, but the mounds of debt many people hold on their credit cards prove that it’s not. “Use your credit card for the convenience it provides and any rewards you might receive, but only charge what you know you can completely pay back at the end of the month,” suggests Jusko. “While some people are building up debt on their credit cards, other people who treat their cards as a tool of convenience are making hundreds of dollars from their cards.”
  7. When a merchant needs to take your card out of view for payment
    This scenario is common when paying your tab at a restaurant or bar. Especially if you’re not traveling overseas, chances are that it’s fine, but allowing any merchant the chance to take your card out of view provides the potential for writing down or taking pictures of the card for use later. “A high-risk destination example is Brazil. During the 2016 Olympics, multiple people had their CCs cloned while at restaurants,” Mark Deane, CEO of ETS Risk Management in Bethesda, Maryland, says. “One security manager of a large corporation even told a story of being at a table and catching the waiter with a cloning device under his jacket, trying to swipe the card at the table. The waiter ran off when challenged.” The best practice is to never to let your card out of your sight and don’t be afraid to ask merchants to bring payment options to you.
  8. When purchasing online while connected to public Wi-Fi
    Inputting any personal information into a website (whether the site itself is secure or not) can pose risks if the Internet connection is not secure, and this includes public Internet or any Internet without password protection. The consequences are that any sensitive personal information (think passwords, personal data, and credit card information) can be read by anyone trying to break through the network. It is best to wait until you are over a secure connection before inputting any sensitive information, like passwords or credit card numbers.
  9. When purchasing something on a public computer
    When surfing the web on a public computer or another person’s computer you don’t know or trust, keep your credit card under lock and key.   A public computer may have devices or software to record all of your keystrokes, also known as keyloggers. The computers also might contain malware with other tools for stealing your information.  Because you can’t verify the security of a public computer, you shouldn’t use your credit card on a website you accessed from that computer.
  10. If you see bulky, plastic, exposed wires on devices you’re about to swipe through
    Point-of-sale devices that have been tampered with (including the setup of “skimmers” to steal payment card data) can be hard to spot, but they are something to be aware of and avoid. If you see bulky, plastic, exposed wires, or other things that look “off” about the device you’re about to use, consider alerting employees or law enforcement.  More and more, consumers should be looking to ‘dip’ instead of ‘swipe.  Swiping reads static data from the mag stripe off the back of the card; dipping reads dynamic data from the chip on the front of the card, adding a level of payment security.
