  As described above, since the mobile device 20 transfers transaction data, tokens, and completion data between the POS 10 and the server 30, the POS 10 needs to be connected to a wide area network such as the Internet to communicate with the server 30. Absent. Therefore, it is possible to reduce the safety problem caused by connecting the POS 10 to the Internet. In addition, the store equipped with the POS 10 does not need to provide communication facilities. The transaction system according to the present embodiment can be applied to a stand-alone store that does not have communication facilities.

== Modification ==
In this embodiment, the transaction system includes a single ePOS 10, but of course, a plurality of ePOS 10 may be provided.
Furthermore, although the transaction system includes a single mobile device 20 in the present embodiment, a plurality of mobile devices 20 may be connected to the ePOS 10. In this case, the ePOS 10 may calculate the distance to each of the mobile devices 20, transmit connection information only to the closest mobile device 20, and establish a session only with the closest device. The ePOS 10 may transmit the connection information only when the distance becomes a predetermined value or less.

  Further, in the present embodiment, the ePOS 10 includes a Bluetooth (registered trademark) unit 107 that can communicate using Bluetooth (registered trademark) LE technology. However, the ePOS 10 is replaced with another Bluetooth (registered trademark) unit 107 in place of the other components. You may provide the radio | wireless communication part which can communicate using a radio | wireless communication technique. In the wireless communication unit, it is preferable to use a lightweight communication technology.

  Further, although the ePOS 10 is realized by a single computer device, the ePOS 10 may be realized by a plurality of devices. For example, ePOS 10 may be implemented with legacy POS devices and reward devices. The reward device is connected to the legacy POS device, can control the legacy POS device, and transmits / receives data to / from the legacy POS device. The reward device may be a computer including a CPU, a memory, a storage device, and a wireless communication unit, and functions other than the POS unit 114 described in the present embodiment may be realized by the reward device.
