Suspect email...

yesterday I bought using official 260 insta e-commerce channel a Insta 360 one R camenra plus some accessory... I used my credits card that normally use all around the world... Well this morning I received an email from e-commerce insta 360 asking a photo of my credits card and a photo of my passport... It is pretty strange as commercial procedure aren't you ? Please let me know if it is your normal operational rule or if it is a fishing identity problem... Thanks Piero Ruffino N/W Italy
