The introduction of contactless payments across London's travel network does not mean the city is preparing to bin the trusty old Oyster system, according to Transport for London.
TfL's Shashi Verma told Techradar: "We expect contactless bank cards to be used alongside Oyster because there will always be people who do not have a contactless credit or debit cards or people who simply don't want to use it."
And there will always be children. No one wants a child to have instant, contactless, password-free access to their bank account. [Techradar]
