To protect your credit cards from being scanned, you can cover the keypad or card reader with your hand when entering your PIN or inserting your card. This simple action can prevent hackers from capturing your information.
Using a credit card with a chip is more secure than a magnetic stripe card, as it's harder to counterfeit. Chip cards use encryption to secure transactions.
Always monitor your accounts regularly to catch any suspicious activity early.
Online Safety
To protect your credit cards from being scanned, it's essential to take the right precautions when shopping online. Make sure to verify that vendors you use online are legitimate and stick to vendors you know and trust. This will help prevent you from falling victim to scams.
When making online purchases, look for signs of a "secure" website, such as a website address that begins with "https" and a closed lock icon in the status bar. This indicates that the website is using extra protection called a Secure Sockets Layer, or SSL.
You can also take steps to limit your exposure to potential hackers. For safer online shopping, keep your own computer free of viruses or spyware, and use a hardwired Internet connection instead of Wi-Fi.
Be Careful with Your Information

Never give your credit card number or personal information to someone you don't trust. This is a crucial step in protecting your credit cards.
Stick to vendors you know and trust, and verify their legitimacy before making a purchase online. You can check with the Better Business Bureau online or in your local area to confirm their reputation.
Be cautious of fake websites that look identical to official sites, but have spelling errors or unusual domains. Scammers can create these sites to steal your information.
Use a secure website that starts with "https" and has a closed lock icon in the status bar. This indicates that the site has extra protection called a Secure Sockets Layer, or SSL.
Don't give out your credit card information over Wi-Fi, as it's vulnerable to hackers. Use a hardwired Internet connection for safer online shopping.
Remember, your debit card also has consumer protection rules, and using Privacy Virtual Cards can mask your actual account details at checkout.
Secure Personal Info on Public Wifi

Public wifi networks are often unsecured, making them easy targets for hackers looking to steal credit card information.
Using public wifi to access personal or financial information is like announcing that information to any hacker on the network.
To stay safe, use a secure wifi network or your mobile data plan to access sensitive information.
Public wifi is not the only option - you can also use a virtual private network (VPN) to encrypt and protect your data from prying eyes.
Heed Browser Warning
Your browser will sometimes display a warning that a website is "not secure." This warning is a cue to proceed with caution because the website doesn't use encryption to protect your data.
Hackers are waiting for personal or financial information to fly across these websites. They're looking for an easy target, so be sure to steer clear.
Count on seeing an "https" in the website's URL if it uses encryption. That "s" means "secure", so you can breathe a little easier.
Protecting Your Credit Cards

To protect your credit cards from being scanned, it's essential to be aware of the methods used by cybercriminals. You can employ several strategies to make scanning your card less likely to happen. For example, you can buy an RFID wallet or card sleeve to block RFID transmissions from cybercriminals' card readers.
When using a payment terminal, it's crucial to choose one with adequate security monitoring, preferably in public view or close to cashiers and bank tellers. If you're unsure about the security of a payment terminal, paying inside or in the view of a cashier is a good idea. You can also consider leaving your card at home and carrying cash when visiting crowded areas or tourist attraction sites.
Here are some additional tips to prevent credit card scanning:
- Activate transaction alerts to spot and flag unauthorized account activity as early as possible.
- Use a chip reader rather than swiping your card, as chip cards are more secure than traditional magnetic stripe cards.
- Insert the chip instead of swiping, as this generates a unique code for that transaction, making it difficult for criminals to use your credit card information.
Inspect Before Use
Inspecting a card reader before using it can save you from potential credit card skimming. Always take a moment to inspect the card reader before inserting your card.

Some skimming devices can be bulky, while others just look a little klutzy. Be on the lookout for any signs of tampering or loose components.
To determine if a card reader is safe to use, look for the following signs of tampering:
- Convex card readers—When hackers place skimmers over readers, they often create a convex shape (curve outwards).
- Damaged card readers—Check if the device is loose or damaged or if any part is misaligned or out of place.
- ATM keypads with moving edges—Try to wiggle the machine's keypad to check if it has moving parts or if the numbers feel thick and hard to press.
- Different terminal shape or look—Does it feel different from the terminals you regularly use? If anything feels odd, do not insert your credit card.
- Damaged gas pump security seals—Gas pumps often have stickers on the dispensers to show they've not been opened or compromised. If the sticker is torn or missing, it may not be a good idea to use that pump.
If you notice anything suspicious, don't use the card reader. It's always better to be safe than sorry.
E-Skimming
E-skimming is a serious threat to your online shopping security. Hackers have found ways to "scan" your card details even online, and it's called e-skimming.
E-skimming involves inserting a credential-stealing code into a popular e-commerce website. If the fraudsters succeed, they'll gain access to all the information you provide to the store at checkout.
This type of hack can be particularly sneaky because it's not like the old days of magnetic stripes and chips.
Fraud Prevention
Fraud prevention is a crucial step in protecting your credit cards from being scanned. You can reduce the risk of online fraud by blanking the security code on the back of your card, making it useless to scammers.

To do this, you can use a nail file to remove most of the marking and then blank what's left with a permanent marker. This will make it difficult for scammers to use your card for online transactions.
Some people choose to write "SEE ID" in place of their signature, indicating that they want a store to ask for identification instead of just doing a bogus check on the signature. This is a good option if you're concerned about fraudulent charges and your card being stolen.
Alternatively, you can blank the signature field with a black marker, which is a more privacy-preserving approach. However, this doesn't mitigate the risk of fraudulent charges when the card is stolen.
Here are some additional tips to help you prevent credit card fraud:
- Check your credit report regularly to detect any discrepancies.
- Check with your bank whether it automatically sends you RFID embedded cards.
- Consider using Privacy Virtual Cards, which mask your actual account details at checkout by replacing your card details with randomly generated card numbers.
Preventing Online Fraud
To prevent online fraud, it's essential to protect your credit card information. You can start by storing your CVV code securely in a password manager and then blanking it from your physical card using a nail file and a permanent marker.

Blanking the CVV code can help reduce the risk of online fraud, but you should also be cautious about disclosing your signature. Some people prefer to write "SEE ID" on their card instead of signing it, which can help prevent fraudulent charges.
However, if you're more concerned about privacy, you can blank the signature field with a black marker. This approach has the drawback of not mitigating the risk of fraudulent charges when the card is stolen.
To further protect yourself, consider using a debit card connected to a Privacy Virtual Card. These cards mask your actual account details at checkout, reducing the chances of hackers obtaining your payment card information.
Here are some key features of Privacy Virtual Cards:
- Comply with Payment Card Industry Data Security Standard (PCI-DSS)
- Integrate with 1Password for strong, unique passwords
- Use private single-tenant data storage networks
- Store data in three separate locations
By taking these steps, you can significantly reduce the risk of online fraud and protect your credit card information.
What Is Scanning?
Scanning is a method used by hackers to access cardholders' data, often by exploiting the magnetic stripe on older credit cards.

Most payment cards today have chips that hold the information, but some cards still have magnetic stripes that can be decoded by a card reader.
Hackers can use scanning to access the data on these magnetic stripes, putting sensitive information at risk.
Banks often encrypt the data on their credit cards' chips to prevent breaches, but hackers keep finding new ways to access cardholders' data.
Credit cards with chips transmit data in a safer way by tokenizing it for each transaction, so credentials aren't transmitted directly.
Radio Frequency Identification (RFID) technology allows some cards to communicate with the reader without swiping or inserting the card, but it requires the card to be extremely close to the reader.
What Is Fraud?
Fraud is a serious issue that can cause significant financial losses and damage to your credit score. Credit card fraud occurs when someone uses your credit card details to make unauthorized purchases or accesses your funds without your knowledge or consent.

Victims of fraud may suffer financial losses, a damaged credit score, and other issues. Fraudulent activity can range from small unauthorized charges to large purchases made by someone who has stolen your credit card information.
You should report any unauthorized charges on your statement immediately if you need to dispute a credit card charge. Your credit card issuer will investigate the charges and, if they are found to be fraudulent, will typically remove them from your account.
Frequently Asked Questions
What blocks a credit card from being scanned?
