TRANSMISSION/RECEPTION SENSOR SYSTEM, MULTI-FUNCTION CARD, AND WEARABLE DEVICE

摘要

The objective of the invention is to provide a transmission/reception sensor system, a multi-function card and a wearable device. The transmission/reception sensor system is used in a multi-function card or the like that has the function of a non-contact IC card and the function of a magnetic stripe card and that further has functions to generate a magnetic card signal and an NFC signal and that has a metal frame and hence a strong resistance to bending or fracture and that also has a Bluetooth (Registered Trademark) function to transmit signals to a device such as a smartphone or the like. The transmission/reception sensor system is characterized by comprising: a magnetic sensor 10 that is constituted by a coil 2 wound about a core 1; an NFC coil 12 that is shaped like a plane; and a metal frame 13a that is placed along the NFC coil 12 and shaped like a loop that has been cut off at one or more positions.
