Abstract
The correlation between a device on the sending side and a device on the receiving side can be controlled with a high degree of freedom when sending and receiving data between multiple devices. A POS system 1 includes a host device 11 with a storage unit 25 having a data storage box 26 that stores data, and a transmission unit that sends data the data storage box 26 stores when data is stored in the data storage box 26; and a display tablet 102 that receives and displays data sent by the host device 11. The display panel 102c of the display tablet 102 is linked to the data storage box 26 of the storage unit 25 of the host device 11.

A point-of-sale (POS) system comprising:
- a POS terminal configured to process an account;
- a host device configured to receive, from the POS terminal, first data related to account processing and second data not related to the account processing;
- and
- a display configured to receive the first data and the second data from the host device, wherein:
- the POS terminal comprises a second display and is configured to display the first data on the second display, designate first unique information, transmit the first data and the first unique information to the host device, designate second unique information, and transmit the second data and the second unique information to the host device,
- the host device is configured to store the first data in a first storage area associated with the first unique information and send the first data and the first unique information to the display by push transmission responsive to receiving the first data and the first unique information from the POS terminal, and store the second data in a second storage area associated with the second unique information and send the second data and the second unique information to the display by push transmission responsive to receiving the second data and the second unique information from the POS terminal, and
- the display comprises a first display and a second display, and is configured to display the first data in a first display area in a first predetermined display mode associated with the first unique information, and to display the second data in a second display area in a second predetermined display mode associated with the second unique information.
