Target identification for sending content from a mobile device

A method, carried out at a mobile device 110, for target identification for a target connectable device 120 includes receiving, via a sensor 112, infrared emissions from infrared light sources 121, each light source 121 being provided by a connectable device 120 in an area. The infrared emissions are analysed, such as by filtering the infrared emissions from a received image captured by a camera 112 of the mobile device 110, to determine a target connectable device 120 at a target position in the area and a blink pattern of infrared emissions is received from the target connectable device 120. The blink pattern is decoded to determine a reference for the target connectable device 120 to enable wireless connection 113, 123 by the mobile device 110 to the target connectable device 120 for data transfer. The blink pattern may be an encoding of the connectable devices identifier or a pattern referenced to the connectable device.
