3.2 Proper Interaction of NFC Devices With the DLP-7970ABP BoosterPack Plug-in
Module
Due to the short range of NFC technology, correct presentation of the BoosterPack plug-in module and
any NFC enabled device is required for proper NFC operation to occur. This is done by aligning the NFC
antennas of each device so they are coupled correctly. This section contains figures that show correct and
incorrect presentations to an NFC BoosterPack plug-in module using an NFC-enabled smartphone, an
NFC/RFID tag, and another NFC BoosterPack plug-in module. Throughout this document, any comments
referring to present or presenting an NFC device or tag to the BoosterPack plug-in module refers to the
following information.
The antenna of the BoosterPack plug-in module is located above the IC circuitry and is indicated by the
traces etched into the PCB, which is the antenna coil (see
Design is not an antenna and cannot be used for NFC communication.
