If the cardholder has already registered for e-Mandate for Standing Instructions, that will no longer be valid as the merchant should not be storing the Full card number anymore from 1st July, 2022. Hence the customer needs to freshly register for Card-on-File tokenization on the card and then give consent for the e-mandate for SI transactions. If the customer chooses not to opt for tokenization, e-mandate for SI transactions cannot be enabled on the card.
