A contact-free data communication system includes a data communications device located in a predetermined place and a contact-free identification tag. The data communications device includes a first data controller and a data global positioning system that acquires positional information of the data communications device and a transmitter that transmits an electromagnetic wave for providing power and transmits the positional information of the data communications device to the contact-free identification tag in a surrounding area of the data communications device. The contact-free identification tag includes a receiver that receives positional information transmitted by the data communications device, a power generator that generates driving power out of the electromagnetic wave for providing power that is transmitted by the data communications device, a generator that generates positional relationship information based on the positional information that is received by the receiver, a display that displays positional relationship information that is generated by the generator, a data storage medium that is nonvolatile and a data storage that stores data in the storage medium.

As a contactless identification tag is removed from a commercial product, a section to be detected is cut and separated from a removal detection circuit section composing the contactless identification tag and remains on the commercial product. When a detection section judges that the section to be detected is removed from the contactless identification tag, the contactless identification tag changes functions.

A printer having a physical connection port and a wireless communication module for sending and receiving data by wireless communication, a received data processor controlling the received data, and a printing mechanism for running a printing process is provided, as is a POS system having such a printer, a wireless communication control method, and a computer readable medium carrying a program for implementing the method. A virtual port emulator on a host system receives display output requests from a POS application running on the host, finds data for a wired connection port on a printer of a stand-alone system linked to the virtual port for the display data, and sends the display data with the connection port data through a physical port on the host to a printer of the host system. Data received by the host printer is then allocated by a first received data processor and sent by wireless communication through a wireless communication device of the host to the stand-alone system printer. The wirelessly transmitted data received through a wireless communication device of the stand-alone system is then distributed by a second received data processor to a display of the stand-alone system through a wired connection port. That display then displays the received information, that is, the display data from the POS application.
