A system for data sharing between a first user and a second user includes a memory and a processor. The processor is configured to execute instructions stored in the memory to associate a unique identifier with a first profile of the first user, the first profile includes user data; obtain, from a second device of the second user, a sensed identifier; and, in response to the sensed identifier matching the unique identifier of the first user, execute instruction to send, to the first user, a first request to share first user data of the first user with the second user; and receive, from the first user, a response to the first request to share the first user data of the first user with the second user. The sensed identifier is captured by a sensor of the second device.
