ShotCode

ShotCode is a circular <a href="/facts/Barcode/Mkh4cCTp">barcode</a> created by High Energy Magic of <a href="/facts/Cambridge_University/0la7aX9o">Cambridge University</a>. It uses a <a href="/facts/Dartboard/dwgFkdYr">dartboard</a>-like circle, with a <a href="/facts/Bullseye_(target)/trLujm6W">bullseye</a> in the centre and datacircles surrounding it. The technology reads databits from the datacircles by measuring the angle and distance from the bullseye for each point.
ShotCodes are designed to be read with a regular camera (including those found on <a href="/facts/Mobile_phone/H3EcqD9h">mobile phones</a> and <a href="/facts/Webcam/1vTYrHWw">webcams</a>) without the need to purchase other specialised hardware. ShotCodes differ from <a href="/facts/Matrix_barcode/Mkh4cCTp">matrix barcodes</a> in that they do not store regular data - rather, they store a look up number consisting of 40 bits of data. This needs to link to a server that holds information regarding a mapped <a href="/facts/Uniform_Resource_Locator/pPD5g7Wq">URL</a> which the reading device can connect to in order to download said data.
