In this era, temperature checks were required when entering an event or facility. Although it is an important task, many people find it tedious, and the temperature check machines are often ignored. The Thermo Selfie was developed to solve this problem and create a new temperature check experience that allows visitors to enter with a smile. The Thermo Selfie can be used as an entrance pass with a photo to prove normal body temperature, and at the same time, it can be used as a memory of having arrived at the event in good health. We aim to introduce this system at various places such as festivals, amusement parks, museums, and sports games. This work was exhibited at the Yurakucho micro FOOD & IDEA MARKET, where men and women of all ages posed with the temperature checker. The non-verbal design and simple operation made it easy for foreign visitors to experience the temperature check. The design of the card can be customized on both the front and back, and the card can be pre-printed to include a surprise coupon, signature and message.
