PROBLEM TO BE SOLVED: To provide a plug unit capable of matching interoperation with a reader writer and interoperation with a device, and a device having the plug unit mounted therein.SOLUTION: A plug unit includes: two interface sections that are non-contact and wired; an electrical power entry section that receives electrical power from a device; an electrical power generation section that uses radio of a reader/writer as a source; a first memory section that is connected to the electrical power entry section and the electrical power generation section and can write and read data in a non-volatile manner; a memory control section that is connected to the electrical power entry section and the electrical power generation section, controls writing of data, obtained through both interfaces, to be written onto the first memory section, and controls reading of data from the first memory section; a signal generation section that generates a signal indicating that the reader/writer is being radiating radio waves; and a second memory section that is connected to the electrical power entry section and the wired interface section, can write and read data in a volatile manner, and has a capacity larger than the first memory section. |
