Apple originally introduced NameDrop when it revealed iOS 17, but the feature was only enabled with a subsequent software update (v17.1). It must also be noted that NameDrop not only facilitates iPhone to iPhone contact exchange, but also allows users to exchange Contact Posters between an iPhone and an Apple Watch, and between two smartwatches, as well. To experience the feature on an Apple Watch, it must be running watchOS 10.1 or a later build.
As far as device compatibility goes, it should work on the current-gen iPhones, dating all the way back to the iPhone XR and the iPhone X smartphones. If you have one of the affordable Apple phones in your hand, NameDrop will be available on the second and third-generation iPhone SE.
For NameDrop exchange between a phone and a smartwatch, you will need the Apple Watch Series 7, Apple Watch Ultra, the second-generation Apple Watch SE, or one of their successors. It’s worth noting here that NameDrop only supports sharing of contact information, and doesn’t work if you seek to update your contact information on an iPhone that already has your number stored on it.
