Patent ID: 8626065

Claim:
A near-field communication (NFC) system comprising: a plug-in device comprising a first NFC sensor; and a mobile wireless communications device comprising a housing defining a plug-in device port, a light source carried by said housing, the light source being positioned to illuminate the plug-in device port, an optical sensor carried by said portable housing, the optical sensor being configured to determine an ambient light level, a second NFC sensor carried by said portable housing, the second NFC sensor being configured to establish NFC communications with said first NEC sensor when in proximity therewith, and a controller carried by said portable housing and coupled to said light source, said optical sensor, and said second NFC sensor, the controller being configured to cause said light source to illuminate the plug-in device port with different luminosities based upon a determination that the first NFC sensor and the second NFC sensor are proximate determined by NFC communications between said first and second NFC sensors and the ambient light level determined by the optical sensor.
