How to Secure QR Codes When Using NFC

When a business uses QR codes and makes a payment through the NFC (Near Field Communication) payments, there is an element of danger regarding security. This can be solved with a few simple steps that must be taken in order to secure QR codes for NFC payments. These must be noted in order to protect everyone using this form of technology. When these steps are taken, there is no need for concern. The technology can be safely used once the following safety steps are taken.

There are two locations of concern with QR codes and NFC transitions. The first is the use of this technology. When the proper steps are taken, the entire process can occur easily and securely. This allows the incoming information to reach the original desired destination, rather than the "hijacked" destination that has been "implanted" in the code or the NFC technology in the smart phone. This is essential for the business to secure for their profits and the security of the customers.

When the code is created for the QR code, encryption must be used to make the code secure. That means that a hacker cannot simply change the destination of the code. Think of it as a person that could simply come in and change the bookmark in a computer that is publicly shared. Marketers are familiar with this tactic. Many times, a marketer will loose their sales or leads because those that use the link add their affiliate link in place of the original one. The result is that the marketer looses their affiliate sale or income from a lead. To prevent this from happening in their QR code, simply encrypt it.

When the NFC unit is used, it can be infected with malicious code that steals the information and uses it for identity theft. In order to protect the money and identity of the individual user, they must use passwords on their smart phone. Set the phone to lock when the phone is not in use. These steps will protect the user and the transaction.

The NFC reader must be encrypted as well. This prevents the wireless stealing of information. This is less of a threat though because the NFC reader, by default the maximum distance that an NFC reader can work is at 4cm [en.wikipedia.org/wiki/Near_field_communication]. This protects most users from someone reading their information for this purpose. While it is less of a distance issue, an issue must be addressed. Setting pass codes and taking care with the use of the smart phone, is the best way to prevent this type of "sniffing" for identity and information.

When these security measures are taken, the danger can be averted. That is how to secure QR codes for NFC payments. It is not an option. It is a liability of the business to ensure the security for and necessary for the user to secure their personal information.
