The invention relates to articles for daily use and provides a two-dimensional code stamp. The two-dimensional code stamp comprises a rectangular stamp head which is connected with a stamp 
handle, the surface of the stamp head is of a lattice structure formed by a plurality of cuboid-shaped 
LED lamp beads, the top surface of each lamp bead is a flat surface, a slot is formed in the middle of each lamp bead, the interior of each slot is movably connected with an 
insertion pin, and a unit body which is as big as the top surface of the corresponding lamp bead is arranged at the top end of each 
insertion pin. A control 
chip controlling the lamp beads to be lighted is arranged in the stamp 
handle and connected with a two-dimensional code 
input device, the two-dimensional code 
input device is used for inputting exterior two-dimensional codes into the control 
chip, and the control 
chip lights the lamp beads corresponding to black dots of a two-dimensional code. The interior of the stamp 
handle is connected with a battery, and the control chip is connected with a 
reset button. The two-dimensional code stamp has the advantages that the two-dimensional codes needing to be printed are input through the 
input device, information is displayed on the stamp head through the control chip, and thus the content of the unit bodies can be conveniently adjusted, adjustment of stamp content is realized, and input 
modes are varied.
