1. A non-touch thermometer to measure a temperature, the non-touch thermometer comprising: a microprocessor; a wireless communication subsystem that is operably coupled to the microprocessor and that is operable to transmit a representation of the temperature; a battery operably coupled to the microprocessor; a single button operably coupled to the microprocessor; a digital infrared sensor operably coupled to the microprocessor with no analog-to-digital converter operably coupled between the digital infrared sensor and the microprocessor, the digital infrared sensor having only digital readout ports; and a display device operably coupled to the microprocessor, wherein the microprocessor is operable to receive from the digital readout ports a digital signal that is representative of an infrared signal detected by the digital infrared sensor and the microprocessor is operable to determine the temperature from the digital signal that is representative of the infrared signal, wherein when connection is established by the wireless communication subsystem to an external device thereafter data is pushed from the non-touch thermometer through the wireless communication subsystem, thereafter the external device controls all flow of the data between the non-touch thermometer and the external device, wherein the connection further comprises an authenticated communication channel.
