a processor configured to:

detect whether the commodity is in the reading range of the optical reading unit, and

cause a notification unit to indicate the commodity has been registered by the wireless tag reading unit only when both the wireless tag reading unit successfully reads the commodity code from the wireless tag and the commodity is presently detected as being in the reading range of the optical reading unit.

2. The commodity registration device according to claim 1 , wherein the processor is further configured to:

acquire commodity information from a commodity master list based on a decoding of the code symbol read by the optical reading unit, and

acquire commodity information from the commodity master list based on the commodity code read from the wireless tag by the wireless tag reading unit.

3. The commodity registration device according to claim 2 , further comprising:

a storage unit storing the commodity master list.

4. The commodity registration device according to claim 2 , wherein the processor is further configured to:

register the commodity in a sales transaction according to the commodity information acquired from the commodity master list.

5. The commodity registration device according to claim 1 , further comprising:

a display screen, wherein

the processor is further configured to:

cause the display screen to indicate the commodity has been registered by the wireless tag reading unit only if both the wireless tag reading unit successfully reads the commodity code from the wireless tag and the commodity is detected as being in the reading range of the optical reading unit at the same time.

6. The commodity registration device according to claim 5 , wherein the notification unit is a speaker configured to emit sound.

7. The commodity registration device according to claim 1 , wherein the notification unit is a speaker configure to emit sound.

8. The commodity registration device according to claim 1 , wherein the processor is further configured to cause the notification unit to indicate the commodity has been successfully registered by the optical reading unit but only if the code symbol is read by optical reading unit and the wireless tag reading unit does not read the commodity code from the wireless tag.

9. The commodity registration device according to claim 8 , wherein

the notification unit is a speaker, and

the processor is further configured to cause the notification unit to emit a first sound to indicate the wireless tag reading unit successfully reads the commodity code from the wireless tag and a second sound to indicate the commodity has been registered by optical reading unit.

10. The commodity registration device according to claim 1 , wherein

the notification unit is a speaker configured to emit sound, and

the processor is further configured to receive a user selection of a notification sound to be emitted by the speaker.

11. The commodity registration device according to claim 1 , further comprising:

a main body configured to be mounted on a checkout counter and having a reading window, wherein

the optical reading unit is inside the main body and positioned to read through the reading window, and

an antenna of the wireless tag reading unit is inside the main body and adjacent to the reading window.

12. A point-of-sale terminal, comprising:

a main body configured to be mounted on a checkout counter and having a reading window;

an optical reading unit inside the main body and configured to read, through the reading window, a code symbol on a commodity within a reading range;

a wireless tag reading unit having an antenna inside the main body and adjacent to the reading window, the wireless tag reading unit configured to read a commodity code from a wireless tag of the commodity in the reading range of the optical reading unit;

a speaker configured to output sounds;

a display screen on an upper end of the main body; and

a processor configured to:

detect whether the commodity is in the reading range of the optical reading unit,

cause the speaker to emit a first sound to indicate the commodity has been registered only when the wireless tag reading unit successfully reads the commodity code from the wireless tag while the commodity is presently detected as being in the reading range of the optical reading unit, and

cause the display screen to indicate the commodity has been registered if the wireless tag reading unit successfully reads the commodity code from the wireless tag while the commodity is presently detected as being in the reading range of the optical reading unit.

13. The point-of-sale terminal according to claim 12 , wherein the processor is further configured to:

acquire commodity information from a commodity master list based on a decoding of the code symbol read by the optical reading unit, and

acquire commodity information from the commodity master list based on the commodity code read from the wireless tag by the wireless tag reading unit.

14. The point-of-sale terminal according to claim 13 , further comprising:

a storage unit storing the commodity master list.

15. The point-of-sale terminal according to claim 13 , wherein the processor is further configured to:

register the commodity in a sales transaction according to the commodity information acquired from the commodity master list.

16. The point-of-sale terminal according to claim 12 , wherein the processor is further configured to cause the speaker to emit a second sound to indicate the commodity has been successfully registered by the optical reading unit but only if the code symbol is read by optical reading unit and the wireless tag reading unit does not read the commodity code from the wireless tag.

17. The point-of-sale terminal according to claim 12 , wherein the processor is further configured to receive a user selection of the first sound.

18. The point-of-sale terminal according to claim 12 , wherein the processor is further configured to detect whether the commodity is in the reading range of the optical reading unit based on an image acquired by the optical reading unit.

19. A non-transitory computer-readable storage medium storing a program for causing a processor of a commodity registration device to perform a method comprising:

detecting whether a commodity is in a reading range of an optical reading unit; and

causing a speaker to emit a first sound to indicate the commodity has been registered by a wireless tag reading unit only when both the wireless tag reading unit successfully reads a commodity code from a wireless tag and the commodity is presently detected as being in the reading range of the optical reading unit.

20. The non-transitory computer-readable storage medium according to claim 19 , the method further comprising:

causing a display screen to indicate the commodity has been registered by the wireless tag reading unit only if both the wireless tag reading unit successfully reads the commodity code from the wireless tag and the commodity is detected as being in the reading range of the optical reading unit at the same time.
