There are a few potential reasons why individuals might not tap off when using contactless payments on buses. Firstly, some bus systems are designed for passengers to only tap on when boarding; in these cases, the fare is automatically calculated based on the boarding point without requiring a tap-off at the end of the journey. This can sometimes be the case on buses operating within fixed-fare zones or when using certain travel cards or passes where a flat fee applies.
Secondly, there might be a lack of awareness or understanding among passengers about the need to tap off. Public transport users who are accustomed to systems where tap-off isn’t necessary might mistakenly assume the same rules apply universally.
Additionally, there could be instances of technical issues or confusion regarding payment procedures. Machines or cards may occasionally malfunction, preventing a successful tap-off.
Lastly, in some cases, passengers might simply forget to tap off, especially if it’s not a usual habit or if they are distracted or in a hurry.
Overall, the behavior of not tapping off might be influenced by a combination of system design, user habits, and occasional errors.
