Once you’ve ventured into the world of near field communication technology, your first question is likely to be “How do I protect my data?” No method is foolproof and taking steps to ensure your credit card information is safe can give you the peace of mind needed to use NFC technology to simplify your transactions without undermining your security or privacy.

First we take a look at what the technology has already done for us. Credit card companies understand how valuable your information is to you and how hackers would love to steal it. To prevent this, credit card payments and other transactions involving sensitive data are conducted over secure channels and data encryption is used. Outside signals are blocked and the data encryption prevents others from reading your data in the unlikely event that a hacker is able to interrupt and redirect your signal. Thanks to the close proximity your smartphone must be to a card reader or other payment device to work, a hacker has to be within a certain range to attempt swiping your data in the first place.

In addition to security measures put in place on the technology itself, you can take steps to protect your information in the event that your smartphone is stolen or lost. Start by locking your phone so that a password is required to unlock it. If a thief nabs your device, they’ll have trouble getting through the password to view your data.

Once you’re smartphone is safely locked so only you can gain access, consider downloading an anti-virus software to prevent hacking. Search for a free software in your smartphone’s app store and check that it has GPS tracking. If your phone is ever lost, you can search for its location from a computer or deactivate the phone so that whoever finds it cannot get in to see your information. These various security measures combined together provide the best protection for your data.
