RFID (Radio Frequency IDentification) are sometimes used interchangeably, but NFC is actually a newer version of RFID. RFID waves can have a longer range. Your side effects are read, while the infrared communication range is limited to 4 inches, making it highly efficient for sensitive applications such as using a credit card or entering security locations.

NFC enables two-way communication while RFID is a one-way reading technology. Transferring photos and connections between common Trit devices is an ephemeral use.

When the connection is established between the phone and the NFC reader device, the encrypted information is exchanged between the two parties in a matter of seconds to perform activities such as payment, scanning, and so on. The high speed of this technology has led to its use in various fields in recent years.

NFC security

NFC is highly secure and is therefore used for mobile and electronic payments. Because the information is exchanged encrypted in this way, it is not possible to infiltrate and steal the information.

The future of NFC

Electronic payments become much faster and more secure as NFC spreads. In addition, if the use of NFC tags to provide information is expanded, the information transfer process will be very fast and easy and there is no need to use information provider brochures. Using this technology, the way electronic services are provided in stores and restaurants can be significantly improved and all the necessary information can be provided to customers quickly.
