1 is read by the barcode scanner 10, a header “AA” is added to the read data, and is output to the device management server 2 as data D 3. Sorting application execution unit 21
b compares the head portion of the data D3 with a known header stored in the pairing data 22b, and if there is a matching header, the tablet stored in the pairing data 22b is associated with the matching header. Get device information. Sorting application execution unit 21b
Removes the header from the data D3 to obtain read data, and outputs the obtained read data to the web application execution unit 21a as read data corresponding to the removed header. Thus, when any of the plurality of barcode scanners 10 reads the product barcode 51, the data of the read product barcode 51 is input to the web application execution unit 21a as input data of the corresponding tablet terminal 4. .
The web application execution unit 21a refers to a product information database (not shown) based on the input product barcode 51, and stores data D4 including product information (product name, unit price, etc.) corresponding to the product barcode 51 on the tablet. Transmit to terminal 4.
Further, the web application execution unit 21a functions as a transfer control unit, and can also read the read data itself extracted from the data D3 by the distribution application execution unit 21b as data D4 to the tablet terminal 4. In this configuration, since the sorting application execution unit 21b removes the header from the data D4, the web application execution unit 21a only receives the read data and data indicating the tablet terminal 4 corresponding to the read data. No header is entered. Therefore, it is not necessary for the web application execution unit 21a to execute processing related to the header.

The communication control unit 21d controls the communication interface 25, receives various data transmitted from the device management server 2, outputs the data to the web application execution unit 21a, and also manages the data output by the web application execution unit 21a. Send to server 2.
The serial driver execution unit 21 e functions as a device driver for controlling the cash drawer 17 connected via the serial interface 24. When the web application execution unit 21a transmits change amount data to the tablet terminal 4 and outputs data for instructing opening of the cash drawer 17, the serial driver execution unit 21e outputs a control signal to the cash drawer 17 according to this data. .
The USB driver execution unit 21 f functions as a device driver for controlling devices connected via the USB interface 23. The USB driver execution unit 21f acquires data input from each device via the USB interface 23 and outputs the data to the web application execution unit 21a, the distribution application execution unit 21b, the pairing application execution unit 21c, and the like. In addition, the USB driver execution unit 21f converts the data output from the web application execution unit 21a, the pairing application execution unit 21c, and the like into the USB
The packet is converted into a packet conforming to the protocol and output to the printer 15, the card reader 16, or the cradle 28.
