The UK Financial Conduct Authority (FCA) extends the deadline to March 14, 2022, to implement Strong Customer Authentication to eCommerce transactions.
Whilst the extended deadline will mean all EEA-UK transactions will require SCA from March 14, 2022. There will be a ramp-up from June 1, 2021, to randomly check and confirm eCommerce transactions are SCA compliant and soft declined if not.
