A RFID tag antenna for wearable application system in microwave frequency band is proposed and presented. The proposed RFID tag antenna is operated in the microwave frequency band of 1 to 12 GHz. Several numbers of the slot resonator are introduced that attached on jeans fabric as substrate material. The presence of the slot resonator also will be used to generate the unique identification or spectral signature of the RFID tag antenna. In real life, the monostatic radar system, which consists of the Vector Network Analyzer and a horn antenna is configured to test the RFID tag antenna. The performances of the proposed RFID tag antenna are evaluated based on their reflection coefficient, operating frequency, and surface current. The obtained results give a good agreement between the measurements and simulation.

Queuing has become a common occurrence in malls, train stations, and others. Queuing especially in healthcare intuitions has become a center of attraction because of the long waiting time either at the registration or in receiving treatments. Therefore, in solving this problem, a smart management waiting system for outpatient clinics is developed by using AppGyver and Backendless as the data storage. This system will be operating by QR code scanning for administrators to obtain patients’ personal information before patients obtain the queue number via MyQUEUE mobile application (patients’ interface). By providing queue numbers through the mobile application, patients don’t have to wait in a small uncomfortable waiting lounge instead patients can wait at their desired places such as cafeteria, in their car, and others. Patients also don’t have to worry about missing their turns because there will be a 10 minutes reminder before their turn. Other than that, there is a feature that digitalized the appointment details which means patients don’t have to worry about missing their appointment book or card. The performance of both systems which are the patients’ interface and administrators’ interface is successfully designed and the output obtained. The administrator is able to assign queue numbers, notify patients 10 minutes before consultation time, and assign follow-up appointments to patients.
