About the Technology
NFC and Contactless Technologies
NFC technology enables simple and safe two-way interactions between electronic devices, allowing consumers to perform contactless transactions, access digital content, and connect electronic devices with a single tap. NFC complements popular wireless technologies such as Bluetooth.
NFC also enables devices to share information at a distance that is less than 10 centimeters. Users can share business cards, make transactions, access information from a smart poster or provide credentials for access control systems with a simple touch.
What does this mean for the end user? Easy connections, quick transactions, and simple data sharing.
Bluetooth wireless technology was designed to replace cables between cell phones, laptops, and other computing and communication devices within a 10-meter range.
Wi-Fi technology was designed and optimized for Local Area Networks (LAN); it provides an extension or replacement of wired networks for dozens of computing devices within a +100-meter range.
ZigBee wireless technology is a standard enabling control and monitoring capabilities for industrial and residential applications within a +100-meter range.
IrDA is a short range (< 1 meter), line-of-sight communication standard for exchange of data over infrared light. IrDA interfaces are frequently used in computers and mobile phones.
RFID (Radio Frequency Identification) is an automatic identification method, relying on storing and remotely retrieving data using devices called RFID tags. An RFID tag is a small object that can be attached to or incorporated into a product. RFID tags contain silicon chips to enable them to receive and respond to queries from an RFID reader/writer.
Contactless smart cards incorporate a chip (microprocessor) that communicates with a card reader through RFID technology. Examples of contactless smart card communications are ISO/IEC 14443 and FeliCa, which allow communications at distances up to 10 cm.
