ABSTRACT

Although the inevitable dependence of humanity on computers is no longer what surprises and amazes some, despite its

irreversible use, there are other technological systems that go unnoticed, such as the popularization of wireless commu-

nication interfaces between computers. The adoption of these wireless interfaces is happening in stages and, curiously,

the individual’s lifestyle as a whole has changed, for, NFC (Near Field Communication) technology allows the exchange

of information in a fast and short-term manner through fully automatic compatible devices. This feature can be used with

cell phones, tablets, electronic cards, tags, or any device that has NFC technology. However, the lack of information

about the device generates a question of how to adapt NFC and control its path? This mechanism not only eliminates the

financial loss from the physical wear and tear of the interface and the consequent interruption of service, but also makes

it possible for countless applications to require only one active device, marking the next big step in the propagation of

wireless communication interfaces. For this reason, it is necessary to analyze how NFC technology works. Since the

financial balance or any control of wireless communication requires balance, it does not matter how much the system is

used, but the effective control of the use, so that the objectives are reached in less time and at the lowest possible cost.

This type of transfer, therefore, enables the exchange of

files between cell phones, such as photos, videos, music,

website links, encrypted data, banking transactions, and may even replace the use of a credit card.
