Bluetooth: What is it and how does it work?
Posted: Thu Jan 30, 2025 10:47 am
NFC (Near Field Communication) is a technology for wireless data transfer over short distances that radically changes our understanding of information exchange. In just a few seconds, you can transfer photos, pay for a purchase or top up a travel card by simply bringing the devices within 10 cm of each other.
What makes NFC particularly convenient is its ability to establish a connection quickly. On average, NFC connects 60 times faster than Bluetooth. This makes the technology ideal for contactless payments: simply hold your smartphone close to the terminal, without the time-consuming process of pairing the device, as is the case with Bluetooth or Wi-Fi.
The first smartphone with NFC was released in 2006 - it was Nokia 6131. In the videos you can see how this legendary mobile phone reads data from a bank card using an NFC chip.
The concept of exchanging data over a distance using tags ghana telegram data is not new. In the 1970s, RFID technology was used in the United States to monitor nuclear waste. Later, it began to be actively implemented in other industries, for example, to track the movement of livestock.

How NFC works in a phone
NFC emerged at the intersection of two principles: electromagnetism and RFID technology, which is based on the transmission of data using radio waves. Its development was inspired by the work of Michael Faraday in the field of electromagnetism and Nikola Tesla, who was the first to think about the wireless transmission of electricity.
In order for two devices to exchange data, they use two coils: one acts as a generator, and the other as a receiver. The generator is connected to a power source, and the receiver is not. It all works by the fact that when these coils come together, one begins to transfer energy to the other. A current is created in the passive coil, which powers the chip with the necessary data.
