NFC is Everywhere

NFC is a proximity technology, which means it only works when two devices are close together or actually in contact. When devices aren’t near each other, NFC is dormant and does not draw power or share information when it shouldn’t.

Any NFC-enabled phone or tablet can serve as a temporary touchscreen for your product, enabling sophisticated interactions and configurability at little additional cost. Your product can be smaller, lighter, more rugged, and less expensive to produce – yet easier to use. NFC reduces the cost of ownership with easier configuration, faster diagnosis, and simpler troubleshooting.

Key NFC use cases

  • IDENTIFICATION and AUTHENTICATION of consumables and accessories to combat counterfeits or configure the main unit based on accessory
  • PARAMETERIZATION and DIAGNOSIS using a phone as extended user interface for small, sealed and unpowered devices
  • FASTER BLUETOOTH and WIFI PAIRING without conflicts by simply tapping with your NFC phone
  • Use phones or smart cards for ACCESS CONTROL to open doors or give access to machine configurations

Connected Tags

These small, passive tag ICs are the best, most cost-effective solution when you have an NFC reader or NFC phone on the other side of the transaction. They use an RF interface that’s fully compliant with the NFC Forum’s specifications, and they support energy harvesting, so there’s no need for a battery to power NFC interactions.

NFC for Industrial

Benefits of NFC for industrial environments

  • Handle complex device settings easily on phone/tablet touchscreen without adding buttons or displays
  • Upgrade device firmware using the phone/tablet connection
  • Use energy harvesting to draw power and extend battery life
  • Implement password protection to avoid unauthorized use
  • Get instant readouts of device status, usage, and diagnostics
  • Give battery-free devices the ability to communicate
  • Let two sealed, IP-rated devices share information
  • Send data at up to 848 kbit/s with a reader or at up to 106 kbit/s with a connected tag
  • Send notifications when accessories need replacement and make offers based on usage patterns
  • Pair devices 20x faster than with BLE or Wi-Fi

NFC for connected home and Internet of Things

NFC for IoT Applications

  • Tap-and-go experiences
  • Faster product registration
  • Intuitive commissioning
  • Quick pairing with Bluetooth and Wi-Fi
  • Extended user interfaces
  • Personalized settings
  • Parental controls
  • Authentication and access rights
  • One-step payments
  • Easy access to online maintenance
  • Efficient data tracking
  • Interactive and personalized advertising

The Internet of Things is changing simple homes into smart homes, where everything from your lights to your locks can be controlled. The router is the heart of an IoT network. The router acts as a gateway, providing Internet access to everything from mobile phones and laptops to appliances like washing machines and refrigerators, wearables, thermostats, multimedia players, and more. NFC enables easy pairing and commissioning, even with unpowered devices. NFC plays a critical role in the transition to connected living, providing new levels of convenience and interaction throughout the home. Appliances and connected devices can be added to the home network with a single tap and, with the right app, our smartphones and tablets can be used to control or configure just about anything.

NFC for Access Control

With NFC, the ability to grant or deny access can be determined from a remote location. Different features of NFC’s access control portfolio allow log time and attendance to be monitored for secure areas and the ability to set limits for access times. Access control can contribute to a reduced maintenance and replacement costs with fewer lost or damaged keys, cards, or badges. Access control is increasing in popularity as there is greater demand for security and simplicity.
