Description: NFC, or Near Field Communication, is a set of communication protocols that allows data transfer between devices at short distances, typically less than 10 centimeters. This technology is based on electromagnetic induction and enables bidirectional communication, meaning both devices can send and receive information. NFC is particularly relevant in the context of wireless communication, as it facilitates quick and secure interactions without the need for manual pairing, as seen with other technologies like Bluetooth. Its integration into various devices has enabled users to make mobile payments, exchange information, and connect devices easily. Additionally, its use has expanded in the realm of the Internet of Things (IoT), where smart devices can communicate with each other efficiently. The versatility of NFC is also reflected in its implementation across different platforms, allowing its use in a wide range of devices, from smartphones to wearables and smart appliances.
History: NFC technology originated from the combination of two earlier technologies: RFID (Radio Frequency Identification) and proximity communication. In 2002, a group of companies, including Sony and NXP Semiconductors, formed the NFC Forum working group to standardize this technology. Since then, NFC has evolved and been integrated into numerous mobile devices, facilitating the development of applications such as mobile payments and data transfer.
Uses: NFC is primarily used for mobile payments, where users can make transactions simply by bringing their device close to a payment terminal. It is also employed in information exchange between devices, such as sharing contacts or web links. Additionally, it is used in access systems, such as public transport cards and smart locks.
Examples: An example of NFC use is Google Pay, which allows users to make payments in stores simply by bringing their phone close to a compatible terminal. Another example is the use of NFC tags on products, which allow consumers to obtain additional information about the product by scanning the tag with their smartphone.
