Proposals by Transport for London to end cash fare payments on the capital's buses has received mixed reviews on the ITV London Facebook page.
Here are some of your views:
I think it's a very good idea, as long as they work out how to ensure that fare-dodging is kept to a minimum.
I dont think thats fair at all. I dont live in London but when I do go I dont always remember my oyster card. Paying with change is handy if you've forgotten.
Public transport should remain readily available to everyone.
