They are still used in the rare cases where, for merchants enrolled on DS 3DSv1 AND 3DSv2, SIPS starts acceptance on 3DSv2 and switches to 3DSv1 :
- In case of non-enrolled 3DSv2 card,
- In case of technical unavailability of 3DSv2.
WL Sips stops the switch over to 3DSv1 from Tuesday 11 October 2022..
