“…RFID systems are classified according to the tag detection distance by the reader, the operating frequency range, using the chip or chipless tag and having a power supply or not [21][22][23]. In an active RFID system, the required energy to activate the tag is supplied from an external power supply (such as a battery), whereas in a passive RFID system, tag energy is supplied from reader signals, where the tag does not have any built-in power supply [24][25][26][27][28].…”

As one of the important components of internet of things (IOT) systems, radio frequency identification (RFID) tags need to be improved in terms of power consumption, size reduction and coding capacity. In conventional methods, designers focus on optimizing resonators, but by focusing on the use of phase coding, a new method can be presented that results in a tag with smaller dimensions and more coding capacity. Hybrid encoding for RFID is based on the phase coding by changing the position of the resonator in the chipless RFID tag. In this paper a C-shaped resonator is proposed to design a chipless tag on the Rogers RT/duroid 5880 laminates. This method proposes different phase values in the resonance frequency as separate codes. The difference between the phases (Φ) of the scattering parameters S11 and S22 is measured to show the effect of position varying of the proposed C-shaped resonator. With the three different values of Φ at the resonance frequency, the proposed RFID tag creates codes 0, 1 and 2, in comparison with the conventional structures that create codes 0 and 1 only, based on the presence or absence of a transition zero at the resonance frequency. The proposed structure was designed, fabricated and measured and measurement results validate this method. Accordingly, an RFID tag with five C-shaped resonators is proposed, where the simulation results of its 3 5 =243 different states are presented in this paper.INDEX TERMS Chipless RFID, Internet of things, Phase-coding, Scattering parameters.

An automated identification and control system has been developed to optimize the entry of students to the University dining room at the National University of San Agustin. The system of attendance and authentication is scalable, reliable and secure. The prototype consists of a master microcontroller with 2 slaves of RFID readers for a 13.56MHz frequency and works with two photoelectric proximity sensors, four actuators of pulse width modulation controlled servo motors (PWM) with a period of 20ms and a tape RGB smart led signaling. The purpose is to automate the entry of students so that long queues do not form while reporting on the attendance of students. Then, the proposal is to use a PWM control algorithm, which will run on the Atmega2560 master microcontroller, which is linked to a server. The database on the server verifies the identity and status of the student through a Java Netbeans graphical interface. The system is optimized to receive a rapid response and to function without line of sight of the tags.
