NFC

(Near Field Communication, "NFC", is an international term).

NFC is a wireless technology that enables short distance transmission of data between devices by keeping them physically close to each other.

NFC

NFC (Near Field Communication) is an advanced technology that uses short distances to wirelessly transmit data between devices. Typically within 4 cm, NFC-enabled devices can communicate with each other, enabling a wide range of applications. NFC is used in mobile payment systems, allows rapid pairing of Bluetooth devices, reading of NFC tags and facilitates data exchange between smartphones, tablets and other compatible devices. The technology uses RFID-like communication, with an NFC chip serving as both a transmitter and receiver to transfer information securely and conveniently. NFC also has applications beyond payments, such as access control and product identification.

NFC examples

A user pays in the store by holding his NFC-enabled smartphone close to the checkout terminal.

A museum guest holds his NFC-enabled device up to an artwork to view more information.

Approaching an NFC-enabled smartphone to an NFC tag can automatically trigger actions such as opening an app.

NFC FAQ

  • NFC (Near Field Communication) is considered a relatively secure technology for data transmission. It uses various security protocols and encryption methods to secure the transmission of sensitive information. In payment systems using NFC, data is encrypted to ensure the confidentiality of financial transactions.

  • A wide range of modern devices are equipped with NFC functionality. These include not only smartphones and tablets, but also other electronic devices such as laptops, smartwatches and even some household appliances. The proliferation of NFC-enabled devices has significantly increased the acceptance and use of this technology.

  • Yes, in many cases, you need a compatible app to perform certain actions related to NFC. For example, scanning NFC tags or performing specific NFC-based actions may require a dedicated app that provides the required functionality.

  • No, NFC is limited to very short distances, usually up to 4 cm. This limited range is a security measure to ensure that communication between devices takes place in close proximity and cannot be intercepted unnoticed from further away.

  • Apart from secure data transmission and payments, NFC has a variety of other applications. These include access control, where NFC tags or cards are used to grant authorizations. NFC is also used in electronic ticketing systems to allow passengers to board and disembark easily. In addition, NFC has applications in identification, contactless keys, and communication between devices for file transfers or wireless connections.
