Code reading device, method, and program
A POS terminal (code reading device) according to one example embodiment of the present invention includes: a code reading unit that reads information of a code based on a reflected light from the code attached to an item; and a discount processing unit that, when the information of the code is not read by using a first light being irradiated on the code and the information of the code is read by using a second light being irradiated on the code, makes a discount associated with the second light for the item, wherein the second light is different from the first light.
1. A code reading device comprising:
a control unit configured to control to irradiate a code attached to an item with a first light and a second light different from the first light;
a reading unit configured to read information corresponding to the code based on a reflected light from the code; and
a processing unit configured to:
apply no discount to a price of the item when a first reading with the first light is successful;
apply a discount to the price of the item by a discount condition associated with the second light when a second reading with the second light is successful based on the first reading being unsuccessful.
2. The code reading device according to claim 1 ,
wherein the control unit performs control to irradiate the code with either the first light or the second light.
3. The code reading device according to claim 1 ,
wherein the second light is a mixed light of at least two lights, and
wherein the processing unit makes the discount associated with the mixed light.
4. The code reading device according to claim 3 , wherein the processing unit makes the largest discount of respective discounts associated with the at least two lights included in the mixed light.
5. The code reading device according to claim 1 , wherein each of the first light and the second light is any one of a red light, a blue light, a green light, and an intermediate-color light.
6. The code reading device according to claim 1 , wherein the first light is a first intermediate-color light, and the second light is a second intermediate-color light that is different from the first intermediate-color light.
7. A code reading method comprising:
controlling to irradiate a code attached to an item with a first light and a second light different from the first light;
reading information corresponding to the code based on a reflected light from the code,
applying no discount to a price of the item when a first reading with the first light is successful; and
applying a discount to a price of the item by a discount condition associated with the second light when a second reading with the second light is successful based on the first reading being unsuccessful.
8. A non-transitory storage medium in which a code reading program is stored, the code reading program that causes a computer to perform:
controlling to irradiate a code attached to an item with a first light and a second light different from the first light;
reading information corresponding to the code based on a reflected light from the code,
applying no discount to a price of the item when a first reading with the first light is successful; and
applying a discount to a price of the item by a discount condition associated with the second light when a second reading with the second light is successful based on the first reading being unsuccessful.
