3.1 Location
3.1.1 A code must be located so that people can scan it without stepping into a roadway or cycle path and without having to adopt awkward body positions.
3.1.2 The optimum QR centred height should be targeted 1000–1200 mm above ground.
3.1.3 It is recommended that the location’s primary QR code should be located at the bottom-right of the main timetable panel.
3.1.4 It should only be located on the bottom-left if absolutely necessary. In addition, to ensure consistency and familiarisation of location: it should be in the same position across all stops in the authority area.
3.1.5 Within the specified bottom right location, the QR code’s exact location should be designed to avoid:
- the fold/hinge edge of a case where reflections and curvature increase;
- being above 1290 mm;
- behind glass with heavy reflections; or
- curved surfaces without testing.
3.1.6 Wherever possible, it is recommended that QR Codes are protected by installation glass or polycarbonate; the use of standalone stickers should be avoided wherever possible.
3.2 Multiple Codes
3.2.1 The use of multiple QR codes on a timetable or poster is not recommended. If, however, this is unavoidable - the primary QR Code should be in the default bottom right hand corner and separated from other QR Codes by at least 50% of the printed material’s width with a minimum of 100 mm separation: to reduce cognitive and physical load and the risk of incorrect scanning.
3.2.2 This is to avoid the particular challenge for visually impaired people successfully scanning the primary QR Code where there is more than one QR Code within the camera’s field of view from the likely scanning distance.
3.3 Separate Plates
3.3.1 Where the QR Code is being provided on a separate plate, this should be installed in a consistent location, which is easily accessible to wheelchair users and those with visual and people with physical impairments.
3.3.2 The recommended height is 1000–1200 mm above ground.
