The payments were made using American Express, MasterCard or Visa Europe contactless payment cards.
According to Tfl, an average of about 33,000 bus journeys every day are paid using the debit, credit or charge cards, with over 1,300 new cards used each day.
TfL Customer Experience director Shashi Verma said it is fantastic that so many people are taking advantage of the ease and convenience of using their contactless payment cards to pay their bus fares.
"Each week we are setting a new record for usage which gives us great confidence for when we launch on the rest of the network and make contactless fully integrated next year," Verma added.
Following the success of this service across its bus network, TfL aims to launch contactless payment card acceptance on the wider transport network, including London Underground, London Overground, DLR and trams next year.
