<p>An information input/output method using a dot code includes the steps as follow. First, at least one dot code corresponding to indicator information is formed on a surface of an object, wherein the dot code is composed of a plurality of blocks, and each block has one bit dot. Each block is divided into a plurality of bit zones arranged in an array. Some of the bit zones arranged in a crisscross form a label zone. Each bit dot forming data information of the dot code is set in the bit zones outside the label zone of the block. Each bit dot forming label information of the dot code is set in the bit zones within the label zone of the block. Then, the surface of the object is optically read to obtain the indicator information corresponding to the dot code.</p> |
