The purpose of this research was to designed and generated barcode system for experimental equipments and tools in physics laboratory school of science University of Phayao. The process of research had 3 steps, 1th step experimental equipments and tools were separated as main sets that were considered by budget year. 2th step they were separated as subsets of main sets that determined by storage room, type of apparatus, mode of operation, consonant in front of equipments and tools name, equipments and tools name and amount of equipments and tools Respectively. 3th step barcodes were generated as 14 numbers and they were tested by user. It was found that all satisfaction of user for barcode system were 53.8% of 5 score and 41.2% of 4 score respectively.
