Abstract
An electronic device includes: a display unit which displays data and a two-dimensional code; and a processor. The processor performs: an encoding process of encoding the data displayed on the display unit into the two-dimensional code; a two-dimensional code displaying process of performing a first masking operation to the two-dimensional code with a first mask pattern and displaying the code having been subjected to the first masking operation on the display unit; and a two-dimensional code changing process of performing a second masking operation to the two-dimensional code with a second mask pattern, and displaying the code having been subjected to the second masking operation instead of the code having been subjected to the first masking operation on the display unit, when a user operation is executed while the two-dimensional code having been subjected to the first masking operation is displayed on the display unit.
