Recently an Australian user named fsjk85 posted on a forum that he had been using the NightShot setting on his camera and seeing what happened on various objects.
This setting is known to be able to see through some materials due to it’s ability to capture ambient light in various places. While he was messing around he decided to take a picture of his iPhone just to see what happens, and realized there was a Matrix 2D bar code on the left back side of the phone.
Matrix bar codes are becoming ever popular nowadays and many phones have programs, that are either built in or can be downloaded, able to scan these bar codes and detect what they mean. Right now it is not known what the code on the phone means but it has been suggested that it probably is tied into the IMEI and/or serial numbers. If anyone is able to decode what it means please by all means let us know!
