The correct answer is RFID.
RFID stands for Radio Frequency Identification. It is a technology that uses radio waves to automatically identify objects. RFID tags are attached to or incorporated into objects, animals, or people for the purpose of identification using radio waves. The tags can be read from several meters away and beyond the line of sight of the reader.
GPS stands for Global Positioning System. It is a satellite-based navigation system that provides location and time information in all weather conditions, anywhere on or near the Earth.
Cloud computing is the on-demand delivery of IT resources over the Internet with pay-as-you-go pricing. Instead of buying, owning, and maintaining physical data centers and servers, you can access technology services, such as computing power, storage, and databases, on an as-needed basis from a cloud provider like Amazon Web Services (AWS).
The Internet of Things (IoT) is a system of interrelated computing devices, mechanical and digital machines, objects, animals or people that are provided with unique identifiers (UIDs) and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction.
RFID is the most likely technology to be used to search tagged objects and mobile devices with the help of browsing an IP address or using the database entry. This is because RFID tags can be read from several meters away and beyond the line of sight of the reader, which makes them ideal for searching for objects in a large area. Additionally, RFID tags can be programmed to store unique identifiers, which can be used to identify specific objects or people. This makes RFID a valuable tool for tracking and locating objects and people.
