Intro: Airport Passport and Fingerprint Scan (TfCD)
A simple prototype has been created to illustrate the user interactions on and next to the screen of a new type of Self Service Baggage Drop-Off machine. This device uses a passport as a travel document (instead of a printed ticket) as well as a fingerprint scanner to verify the identity of the passenger.
The prototype illustrates the interactions with these components. The actions are simplified by using a lightsensor to mimic an NFC reader reading the passport and a pressure sensor instead of a fingerprint scanner.
Watch our video for the end result!
Step 1: Components:
The necessary components are:
- Arduino kit
- Power source (laptop)
- 6 (blue) LEDs
- Pressure sensor
- Light sensor
- Cardboard box
- Paper mock up of device interfaces
Step 2: Programming the Arduino
Create a code for the Arduino which:
- Pulsates the LEDs on an off when the light sensor ("passport scanner") is activated
- Turns on the LEDs one after each other when the pressure sensor ("fingerprint scanner") is pressed in
- Flashes the LEDs when the pressure sensor is pressed in long enough the light up all the LEDs
Our use our code which can be found here!
Step 3: Building the Circuit
Build a circuit which includes the 6 LEDs, light sensor and pressure sensor, all with their appropriate resistors. It should look something like this (a mess of wires!).
Step 4: Building the Prototype
To create an appropriate prototype for testing the user interaction, a housing has been made out of a cardboard box. The LEDs, pressuresensor and light sensor have been pierced through the lid.
Printed screens of the interface (paper prototype) have been created and stuck onto the the outside of the box. When testing the sheets of paper are flipped through, to simulate the transition between the different digital screens.
The prototype is ready, have fun testing!
