payment NFC

      It is probable that you have never used a NCF chip to buy via contactless, since they are becoming to be included in the most and newest smartphones. However, we are sure you have heard of it.


      What NFC technology is?

      Near Field Communication is a wireless technology that operates in the 13.56 MHz band (you don’t need a license to be able to use this kind of band). It derived from the RFID labels.

      NFC is an open platform designed for mobile phones and devices. Its transfer rate can reach 424 kbit/s so it is not suitable for the transmission of large amounts of data, but for instant communication (example: identification and validation of equipment/people).

      Its main advantage is the speed of communication, which is almost instantaneous without previous pairing. Another advantage is its transparent use and that the fact that NFC devices are able to send and receive information simultaneously. Nevertheless, it has some disadvantages like the small scope: it runs in the range of 20 cm.

      NFC technology can operate in two modes:

      • Active: in which both devices generate an electromagnetic field and exchange data.
      • Passive: in which there is only one active device and the other uses that field to exchange information.

      Due to the fact that we use radio frequency communication, we are always at risk that our transmission will be intercepted. In this case, because of its short scope we have an advantage about this safety issue, but we can’t dismiss the possible copy of the codes chip for a fraudulent use. Besides this risk, there are also other possible dangers – the modification or insertion of errors.

      NFC usage

      The most common uses of this way of wireless data transmission are: identification, collection and exchange of information and over all, the payment system.

      • Identification: a possible use for the NFC technology is to use it in places where identification is required. We let our mobile be read by a reader. An example is the season ticket for public transports.
      • Data collection/exchange: Google could be the most important company that that makes the most out of this system combined with RFID labels. This company can mark where we are or send information about an event almost instantly.
      • Mobile payment: This is the most interesting use of NFC. This is probably the technology of the future concerning payment methods. Its comfortable usage and easy mode to integrate expenses in our bill or relate them with our bank account are the main advantages of this payment method.

      You can see how this system works on a demo performed at the Mobile World Congress in 2011:

      iPhone NFC

      The incorporation of an NFC chip into the iPhone is something that has been talked about for a long time now, before Apple launched the iPhone 5. Apple presented Passbook instead of this system, a kind of virtual wallet where you can store your tickets, gift certificates and much more. According to PhoneArena, North American telecom company Verizon confirmed NFC incorporation into the next iPhone, and if the rumours aren’t lying it’ll be the iPhone 5S.

      The rumor has it that in Verizon data base appeared a clear reference to the fact that the iPhone 5S will have NFC. It will be a step towards Apple’s product standardization, taking into account that the company normally opts for a platform that isn’t compatible with others. The guys from Cupertino would finally start competing with other mobile payment tools, like Google Wallet.

      Predictions of NFC for mobile devices

      According to Juniper Research, the number of users using NCF payment services, like Apple Pay or Google Wallet, will increase from 100 million to 519 million people for the coming years. In its analysis, this consultant assures that smartphones will modify the panorama and bank business models, operators and mobile developers.
      According to the manager of Gartner’s investigations, Sandy Shen, mobile transactions will be an industry with a value over $721M.

      In addition, Juniper Research estimates that there will be more than 1,500M of mobile wallets around the world by 2018, and out of three smartphones will be able to pay via contactless, 50% of them will belong to users from emerging markets.

      On the other hand, Apple and Google will not continue to lead the list of most common mobile payment services. There are more industries interested in the development of this tendency. For example, the industry Oberthur Technologies could be the first option to buy through a NFC payment, even if nowadays they are not popularly known.
