RFID embedded cards transmit data through the use of radio frequencies. These cards have been in use in Europe for many years, but they have only recently begun to be used in the United States. To put it another way, consumers should be able to use these cards to pay for purchases in stores and restaurants without having to swipe their cards through a scanner. Many people, however, remain concerned that RFID technology may also allow thieves to use scanners to intercept radio waves and steal the information contained within the card’s information. Despite the fact that technology has made significant security improvements in recent years, there are still some areas of concern.
Method 1 Being Careful and Changing Habits
1. Organize your RFID cards in your wallet by placing them next to each other. This can make it more difficult for thieves to read a specific card, but the protection is only temporary.
2. Your RFID cards should be kept in a front pocket. In the event that you carry your credit cards in a wallet in your back pocket, you may be more vulnerable to thieves who may approach you from behind and scan your cards with their scanning device. If you move your cards to your front pocket, you will be more aware of the people in front of you and will be less likely to become a victim of crime.
3. When using your credit cards, keep an eye out for other people in your immediate vicinity. New RFID technology limits the ability of thieves to scan your cards beyond a short distance and only at the point of sale for some products on the market. X Information gathered from various sources
Before you use your credit card in a store, look around you to make sure no one is standing within a few feet of you. If there isn’t anyone nearby, your transaction should be secure.
4. Keep your RFID cards at home and only use them for online purchases. You can use other credit cards or cash to make purchases outside your home if you are really concerned about RFID technology. If you are really concerned about RFID technology, this is a possible solution for your situation. However, identity theft through the use of an online computer is likely to be a greater risk than using RFID technology in a retail setting.
5. Keep an eye on your credit card statements for unusual activity or mistakes. It is possible that this will not prevent thieves from stealing the information from your card, but regularly reviewing your credit card statements will assist you and the credit card company in identifying any unauthorised purchases and can help you limit your potential losses.  According to some sources, keeping track of your credit card statements on a regular basis is the “best” way to protect yourself from identity theft.
Method 2 Making and Using Shields
1. Purchase an RFID shield wallet or credit card sleeve to protect your credit cards. It is possible to purchase commercial products that claim to prevent RFID scanners from obtaining your personal information from the Internet. Individual sleeves for your RFID cards or wallets that are lined with a material that prevents scanners from reading them are examples of this.
2. Purchase an RFID jamming card or device to protect yourself from RFID theft. The device, which is about the size of a credit card, emits its own RFID signal, which causes scanners attempting to obtain your credit card information to be deterred from obtaining it.
3. Make a shield out of aluminium foil. This is the “low-tech” approach, but it is also the cheapest and most straightforward. Cut two pieces of paper or cardboard to the size of a credit card, wrap each piece in aluminium foil, and carry them in your wallet around your credit cards as an extra layer of protection. Most electronic signals will be disrupted by the aluminium.
4. Alternatively, you can wrap each credit card individually in aluminium foil and store the wrapped cards in your wallet. The foil protects the card from being scanned by scanners.
Method 3 Keeping Credit Cards Safe for Online Purchases
1. Verify that the vendors you use on the internet are legitimate before making a purchase. Stick with vendors who you have worked with in the past and who you are familiar with and trust. If you have any concerns, you can contact the Better Business Bureau, which can be found online at http://www.bbb.org/ or in person in the area where the company conducts its operations.
2. Look for indicators that a website is “secure.” True secure websites employ an additional layer of protection known as a Secure Sockets Layer, or SSL, and their website addresses will begin with “https” rather than the standard “http.” The status bar at the bottom of the page will also indicate that the site is secure, with a closed lock icon displayed. If you don’t see the “https” address or the padlock at the bottom of the page, you should think about making your purchase from a different website.
3. You are responsible for the upkeep of your computer. Maintaining a virus- and spyware-free computer on your own computer is essential for safer online shopping. There are software products that you can purchase or download for free from the internet that will assist you in keeping your computer as clean as possible.
4. Purchases of Wi-Fi should be limited. Because anything wireless is potentially vulnerable to hacking by individuals who are able to intercept the radio signal, using a hardwired Internet connection is the most secure method of conducting online shopping.
5. For online shopping, a temporary credit card can be used. Many banks and credit card companies will provide this service at no cost to the customer. You can obtain a card number that is separate from your actual account, but the bank will link it to your account for any legitimate purchases you make with the card number.
