I tell or text them in setting up meeting that I bring my card as well. Just the card. The likelihood that it is fake or borrowed is small since I seek out vaccinated providers only by their ads or a follow up communication with them. This eliminates many providers but in my mind I can’t see any provider being in this business and touting they are not vaccinated in this day and age. Also, I have eliminated traveling girls. If they show they are in Miami one week then Chicago, that’s a not go. Locals only.
