| Features | Specs |
| RFID Readers |
| Reader | Can be wireless handheld or fixed reader/antenna devices |
| Virtual portable memory | 1-50 Mbytes |
| Reader capability | Multi tag reading |
| Transmitter/receiver frequency | 1-1000 MHz |
| Tag read range | 1-500 feet |
| Database | Self-contained |
| Immunity | Noise and interference (Ting, Kwok, Tsang, & Lee, 2011a) |
| Communication standards | RS 232 and RS 485 |
| Anti-collision capability | Built-in |

| RFID Tags |
| Tags type | Active and passive tags |
| Battery life | Active tags 1-5 years (depending upon the data transmitted frequency) and passive tags requires no battery (Mogre, 2009) |
| Tag read range | For active tags 1-500 feet (depending upon readers sensitivity settings) and for passive tags 1-20 feet read range |
| Life cycle | Active tags up to 5-10 years and passive tags up to 20 years |
| Tags Frequencies | Microwave, Ultra High, High and Low frequency (Ostbye et al., 2003) |
| Microwave frequency | Works on 2.5 GHz with maximum 5 feet reading range |
| Ultra High frequency | Works on 860-930 MHz and has maximum 20 feet reading range |
| High frequency | Works on 13.56 MHz, used for short reading range applications and has less than 3 feet reading range |
| Low frequency | Works on 125 KHz, used for short reading range applications and has maximum 2 feet reading range |
| Storage Capacity | 1 byte – 10 Mbytes |
| Wake up frequency | 1-500 MHz |
| Tags classification | Class 0, Class 1, Class 2, Class 3 and Class 4 (Massuod & Hassan, 2012) |
| Class 0 | Read only, id number is written only once during manufacture |
| Class 1 | Write Once Read Many, data can be written by manufacturer or the user one time |
| Class 2 | Read-Write, user can access read and write operation into the tags memory |
| Class 3 | Read-Write with sensors, records parameters like motion, pressure and temperature |
| Class 4 | Read-write with integrated transmitter, communicates with other tags without the presence of readers |
| RFID Field Generator |
| Functionality | Produce 1-500 MHz field to wake-up active tags |
| Tags wake-up range | 10-200 feet (depending upon field generator strength) |
| Flexible strength setting | Allow adjustment of wake-up tag range |
| Provides cost effective tracking system | Cost lower than RFID reader |
| Optional | Motion detection |
| RFID Antennas |
| Functionality | Used as a medium for tag reading |
| Antennas types | Omni directional, dipole or multi pole, patch, linear polarized, circular polarized, stick, beam-forming or phased-array elements, Gate and adaptive antennas (Ahsan et al., 2010) |
| Operating Temperature | -30 °C-70 °C |
