Check-in Device
NFC attendance
Attendance, taken with a tap. An Arduino reads NFC to check people in, then sends each check-in through an ExpressJS API to a cloud database, so the records update in real time and can be reached from one place. The device was designed to draw little power, stay connected, and keep its data secure on the way from the hardware to the cloud.
