2D barcodes

2D Barcode Tags - Mobile code technology

Two-dimensional (2D) mobile codes are similar to linear (one-dimensional) barcodes, but because their matrix structure can hold more information, they can be used to transmit much more information. Whereas a linear barcodes are limited to approximately 20 characters of information, a 2D barcode can represent between 2,000 and 4,000 alphanumeric characters.

2D mobile codes provide a unique opportunity to provide students with immediate information about any object in a contextual setting. For example, placing mobile codes beside works of art, students could use their mobile phones to instantly access additional information about the artwork, the artist, the history and even link to a website for further information. Mobile codes on plant tags would provide instant botanical information. The educational opportunities to apply this inexpensive technology are limitless.
