The invention provides for a mobile telecommunications device that decodes tags of coded data printed on media present at points internal and external of the device. The device has an image sensor and a beam splitter for deflecting incoming light onto the image sensor. The device also includes a first infrared LED operatively directing light onto external media at the external point, with an infrared filter configured to receive light reflected from the external media onto the beam splitter. Also included is a second infrared LED operatively directing light onto media present in the internal pathway, with a mirror arrangement configured to direct light reflected from the internal media into the beam splitter.
