The host server can have several functions. It can configure, manage, and monitor the readers. It can also host specific application software, such as card catalogue software for a library's RFID system. The host system can act as a middleman between the RFID system and other software applications that a client may have, such as asset inventory, purchasing, patient records, or pharmaceutical supplies.

RTLS Healthcare Example

A hospital needs a fast and effective way of finding people (e.g., patients, doctors, nurses, orderly, translators, or duty staff), as well as locating key medical. The capability to identify persons and equipment in the hospital through the use of RFID addresses this need and provides several important benefits.

For hospital staff, an RFID chip is embedded into a smart card. Applications for the smart card for hospital staff include identifying their location, access control, point of sale applications, parking garage access, and event management. The system would also have the capability to list staff members on duty.

The hospital can tag mobile medical equipment. The RFID system can quickly locate needed medical equipment saving significant time for staff while interfacing into an asset management system.

Patients are provided with wristbands with embedded RFID chips, allowing patients to be automatically identified and located. The tags are also critical as a security measure, providing an alarm if a patient or infant were to leave the hospital premises unauthorized.

These systems can automatically track and time stamp the progress of people or assets through a process, such as following a patient's emergency room wait time, time spent in the operating room, and total time until discharge. Such a system can be utilized for quality control and improves delivery of services.
