Google is developing a new Android feature similar to one found on iOS.

Android users might get a timesaving way to share contact info with other Android users,
NameDrop offers a convenient way to exchange contact details with fellow iPhone users. If the initial exchange occurs within AirDrop range but the users move apart, the remaining data is securely transmitted via the internet. Users can also choose to only receive another person's contact information without sharing their own Contact Poster.
NameDrop employs Near Field Communications (NFC) to initiate the connection between iPhones, similar to Apple Pay's tap-to-pay function. This signals both devices to share information. AirDrop then takes over, using Bluetooth and Wi-Fi for device discovery and data transfer to swap Contact Posters. In essence, NFC starts the NameDrop process, and AirDrop finalizes it.
Reportedly, Google is developing a similar feature for Android, internally named "Gesture Exchange" and "Contact Exchange." Android Authority enabled Contact Exchange Activity in Google Play Services v25.46.31, revealing that users can select which information to share.
Users can share any combination of these details. Selecting "Receive only" allows a user to obtain the other person's information without sharing their own. The received information is displayed as a "Contact received" page. Saving it creates a new contact on the phone, with icons for initiating video calls or sending messages.
Google might also use NFC to establish the connection between Android phones, with Bluetooth or NFC completing the process. The release timeline for this feature remains unknown. Its addition would be a welcome enhancement for Android users.
