A portable information detection and processing device, comprising:

• an information detection unit, for acquiring information recorded by at least one functional element;
• a memory unit, for storing recognition data of the at least one functional element and the information acquired by the information detection unit;
• a display unit, for displaying the recognition data of the functional element and the information acquired by the information detection unit;
• and
• an information processing unit, connected to the information detection unit, the memory unit and the display unit, for processing the recognition data of the functional element and the information acquired by the information detection unit, to control the information detection unit, the memory unit and the display unit,
• wherein the information processing unit performs an operation on a value of the information acquired by the information detection unit to generate an operation result, and when the operation result exceeds a threshold, the information processing unit generates an activation signal to activate the display unit to display the operation result on the display unit.
