Avoid strong reflections on the device screen, as this will affect how quickly and easily a barcode can be scanned.
Ensure the height elevation and angle of the device provides allows for easy access to users of varying height access.:
As a starting point, avoid having the top of the device higher than 120cm from the ground.
Tilt device slightly upwards, but avoid If in a low position, try slightly tilting the device upwards, while avoiding strong reflections from overhead lighting.
If it is an option to do so, consider having two kiosks at main entrances; one placed lower, and the other higher.
Do no not place and any obstacles in front of kiosk devices that which would force users to reach further than necessary, of or even block access for wheelchairsby wheelchair.
Consider if the kiosk can easily be approached from the side, or front only. Side-approach (or parallel-approach) allows wheelchair users to get closer, thus reach higher more comfortably.
Ensure there’s sufficient space in front of the kiosk, where multiple people can wait without encroaching on each other’s privacy, and for wheelchairs to turn around. Especially where only front-approach is possible.
