PROBLEM TO BE SOLVED: To provide a method for manufacturing a pull-tab of high productivity, and a method for using the pull-tab favorable for industrial use in which concealment and exposure are freely executed, and a two-dimensional code with excellent reading operability by a portable terminal or the like is displayed on a beverage can.SOLUTION: (1) A printing area 1 is formed at the position opposing the upper surface of a can lid on the back side of a pull-tab. (2) The printing area 1 is fixed to or integrated with the pull-tab 4. (3) A two-dimensional code 2 is printed on the printing area 1 by laser marker in the manufacturing method. (4) When the pull-tab 4 is fitted to a can lid, 60% of the printing area 1 is concealed. (5) After a purchaser purchases a beverage can, the purchaser pulls up the pull-tab 4 to expose 60% of the two-dimensional code 2 concealed by 60%. Information encoded to the two-dimensional code 2 is read, and decoded to communicate with a server of a beverage maker. |
