Abstract
Radio Frequency Identification (RFID) is a technology that uses radio frequency signals to identify tagged objects. RFID is an important technology used by the Internet of Things (IoT) applications. This technology enables communication between the main devices used in RFID system, the reader, and the tags. The tags share a common communication channel. Therefore, if more than one tag tries to send information at the same time, the reader will be incapable of differentiating these signals in the case of radio signals interference. This phenomenon is known as tag collision problem. The problem of tag collision is one of the major disadvantages for fast tagged-object identification in supply chain management. This chapter describes four different types of binary search algorithms for avoidance of tag collision, and then presents a performance measurement mechanism for RFID application system. Finally, simulation-based experimental results on the performance of these algorithms are presented.

Radio Frequency Identification and Its Application in E-Commerce
Active tag is the RFID tag with an onboard power supply (i.e. battery) and may also include elements for performing specialised tasks (i.e. sensory elements for temperature, humidity, positioning system, etc.). Use of battery in active tag results in longer reading range and increased readability in harsh environments.

Radio Frequency Identification (RFID) Technology
An active tag is a type of RFID tag that has its own power supply (battery or external power) and, when interrogated by a reader, the tag emits its own signal. Active tags have far greater read distances than passive tags, and they can be combined with sensors to provide information on the environment and condition of the item. They are also more expensive than passive tags and, due to the battery, have a limited life span.

RFID Tagging of Pharmaceuticals
A type of RFID tag that has its own power supply (battery or external power), and, when interrogated by a reader, the tag emits its own signal. Typically, active tags have far greater read distances than passive tags, and they can be combined with sensors to provide information on the environment and condition of the item. They are also more expensive than passive tags and – due to the battery – have a limited life span.
