Credit Cards Security – To ensure that your credit card safe from unauthorized charges, here are some ways you can protect your credit:

  • Do not give your credit card account number out over the phone without knowing why. Know who is asking for your phone number before giving a number. Make sure that the person is employed by a leading catalog company, organization, or business. If it is unsolicited calls, do not give out the number.
  • Do not ever use your credit card on an unsecured website. Online purchases are easy and fast. However, unless the website is secure, your credit card numbers at risk of being stolen. Use only sites that explicitly state they are a safe and reputable business and that such claims can be verified.
  • Do not ever put your credit card account number on the outside of an envelope or a postcard. Anyone can see this information. If necessary, including credit card or account number information in the envelope and make sure any such details cannot be seen through the envelope.
  • Do not ever post confidential information on social networking sites. Many people are happy to share all sorts of things about their lives on Facebook, Twitter, MySpace, and LinkedIn. However, sharing too much can leave you open to ID theft.
  • Do not sign a blank charge slip. Always know how much it will cost and verify the amount on the receipt given to you.
  • You are checking your monthly statement. Do not automatically pay your credit card bill every month or let it sit on your desk. Open your account immediately and look closely at every cost listed to verify the amount and whether you make the purchase. If something is wrong, contact your credit card company directly. In this way, you shall be able to determine whether there was a mistake or whether other unauthorized charges have recently been made to your card.
  • Scissors time through a credit card account numbers. When you get a new card or close the account, cut up old cards with account numbers that cannot be identified.
  • Protect your credit card and PIN in an ATM or when using the phone. If you use your credit card for a cash advance or long-distance charges on a public telephone, be aware of people around you. Some credit card theft and credit card memorization of the PIN you push the button on the phone. Use your body to block path of anyone’s vision.
  • Carry as few credit cards as possible. People with multiple credit cards should only carry a few that they wish to use. For example, if you have an emergency card and a gas card, you also need to bring standard credit cards such as Visa or other credit card stores unless you plan to go to the store. By being selective with the card with you, if you happen to lose your wallet or purse, only a few cards are at risk of abuse than all of them. If you lose your credit card, report it to your issuer immediately.

How Can I Secure My Credit Card?

  • This tip may seem obvious, but people still do share a photo of their credit card on the social network. The picture above, taken from Twitter, shows an example of what not to do. I do obscure critical information as the person who shared it did not. Never share any photos of documents in social networks 🙂
  • CVV code on back of card is only useful for online shopping so that once it is securely stored in the password manager you are, there is no reason not to scratch from the card. I have found she works best to use a nail file to partially remove whats mark and then leave with a permanent marker. The outcome of this process is shown in the picture above.
  • You do not want to reveal your signature, mainly because it adds nothing in terms of security. However, you cannot leave an adequate space because the attacker would only sign it when they steal. This leaves us with two options, both of which have some supporters:

SEE write in the Signature ID

SEE write in the signature ID, as seen in the screenshot from one of my cards on top. This indicates that you want the store to ask for ID, not only do the forged checks on signatures. This is the preferred option if you are more concerned about the allegations of fraud and stolen cards. Back when it is my favorite method, the Apple Store is always asking me for my ID when I got a card with SEE ID, which shows sometimes work.

Blanking field with a black marker signature is another option, as shown in the figure above. This option will appeal to the privacy-conscious people who prefer to avoid showing their ID at the store. This approach is more privacy-preserving and lacks the risk of fraudulent charges when the card is stolen. This is the approach that I moved recently.

  • If you have a current card, chances are it is contactless, which may leave you open to attack long-distance and privacy leakage. Use the Android app, I can easily use the remote NFC reader to take my credit card number, expiration date, and a log of the last ten transactions. Testing with various cards shows that the recent transactions are not always reported, especially in the European menu. Researchers have shown that it is probable to read this information from the (short) distance of 45 cm; thus, protecting against remote reading is essential.

How Can I Protect My Credit Card Online?

It pays to protect yourself when shopping online to avoid getting more than you bargained for.

With high-profile data breaches that could potentially affect millions of people, here are some tips specific cards to keep in mind when nearly swiping your plastic.


  • I was using a credit card. Debit cards often do not have the same level of fraud prevention and protection.
  • Just enter the details on a secure site. Look for https connection and a valid security certificate.
  • Do not send credit card details via email or social media.
  • Keep your antivirus software and browser up to date.
  • Avoid clicking on a link from an email deal because it may be a phishing attempt.

Turn on your credit card an extra layer of security.

Many credit cards will have an additional layer of security that might not be enabled by default. MasterCard SecureCode is when you enter the code every time you make a transaction at a supported site.

Verified by Visa also requires a passcode to authorize the purchase. On top of this security, some banks also have their verification system that works in place SecureCode and Verified by Visa. This may include sending a bank PIN or one-time security code to your phone as a second layer of authorization. Check with the bank or monetary organization to see if one of these options available.

Both Mastercard and Visa offer Zero Liability protection against fraudulent transactions both for online and offline use.

Consider a separate card for online transactions.

A prepaid card is one option for those who want to maintain an online purchase entirely separate from daily credit card transactions.

They allow you to load a certain amount of money at the time of purchase. Gains were plentiful when it comes to using a prepaid card for online shopping, but the great thing is that even if the card details are disrupted somewhere along the chain, there is a limit to the amount of money taken.

How Can Credit Cards Be More Secure Than Cash?

Many people do not realize this, but do not use credit can dramatically hurt your credit score. Your credit score is mostly based on your credit history and how you take advantage of the credit. If you do not have a credit record and do not use it regularly, there is nothing to base a score, so your credit score will be low enough.

Bad credit can cost you money. Have bad credit will cost when it comes to taking out a mortgage or getting insured. Insurance companies can factor in your credit score when deciding your premium. And the bank will hit you with a higher interest rate on a loan or mortgage if your credit score is low. If you do not know the credit score, credit card offers a credit score is updated every month on your bill, so you can track your progress as you improve your score.


The use of cash should be safe. With all the hacking occurred recently, it would make sense that money will help prevent identity thieves. Unfortunately, that did not happen, unless you hide all your money under your mattress. Banks are just as vulnerable to hacks as credit card companies, many banks. If you use a debit card or online banking, your account can be easily hacked.

The worst part about using a debit card for purchases is that you must enter your PIN when you pay. This gives the hacker direct access to your bank account, and they can quickly drain your account before you can blink. Simultaneously, fraud protection was build into many credit cards. And it was easier to get reimburse for fraudulent charges. Getting the money back to your bank account when it was drain much more difficult.


This is a relatively simple point, but one of the most important when it comes to saving money. Convenience can swipe your credit card instead of continually running ATM or should count out the exact amount is quite clear. Many car rentals, hotels, and the airline also will take cash or debit cards even more.

The main benefit is to have a detailed list of all who have spent money every month—having an online account of all the transactions you make it easier to administer and enforce the budget. Do you know where all your money goes, which is very hard to do with the cash?
