Everything you need to go from zero to hero in QR technology. Read on for examples, "how-to", history and even a bit of the strange.

Near Field Communication Payment & NFC Payment

In Japan, people have been using their mobile phones since the late 90s to purchase items but in the United States and Europe this technology is just beginning to emerge. Near field communication or NFC is a technology that allows two devices to share information when in close proximity to one another. Near field communication is thought to be much safer than traditional credit cards and could cut down on identity theft and the stealing of credit card information.

NFC payment works by taking and correlating two points of data for every transaction, RFID as well as an encrypted password. A secure radio within the mobile phone sends a special code to the retailer’s payment system which in turn sends transaction details to the user’s phone. The user then needs to enter a PIN number to approve the specific transaction.

To stay protected against malware and hackers, the NFC radio is specially designed to be isolated from the rest of the phone’s operating system and this way only one app on the phone would be capable or approving a transaction. This technology makes near field communications very safe.

Currently, the only significant NFC payment system available in the United States is a system called Google Wallet. While Google boasts that the technology is accepted at over 300,000 retailers around the world, it is used much less often. Currently, Google Wallet only works with MasterCard PayPass terminals and is only compatible with Nexus 4G phones and PayPass enabled credit cards.

While it might seem like a small start, near field communication payment has the ability to take over traditional credit card payments. It is predicted that the number of NFC payments through mobile devices will significantly increase rapidly. Many companies are currently working on near field communications technology on their own.
