TapNLink NFC

TapNLink NFC (Type5) module for local connection of mobile devices to microcontroller-based electronic systems.

TapNLink NFC modules provide a contactless interface for linking mobile devices to equipment and appliances. Using TapNLink 3-stroke configuration, users interact with appliances from an app on their mobile in three intuitive steps: 1) tap to launch the app and recuperate the appliance's parameters, 2) modify parameters in the app, and 3) tap again to transfer the new appliance parameters.

For appliance designers, TapNLink connects directly to their system's microcontroller. It integrates into and is powered by the target system. however, the integration requires no coding or hardware development.

All TapNLink products are easily configured to control access to data in the target system by different types of users. TapNLink facilitates rapid creation of user interfaces that run on Android, iOS and Windows-based mobile devices.
