IoT & RFID in inventory management
Radio frequency identification system (RFID) is an automatic technology and aids machines or computers to identify objects, record metadata or control individual target through radio waves. It allows a business to identify individual products and components, and to track them throughout the supply chain from production to point-of-sale. A typically RFID system is consisted of tags (transmitters/ responders) and readers (transmitters/receivers). The tag is a microchip connected with an antenna, which can be attached to an object as the identifier of the object. The RFID reader communicates with the RFID tag using radio waves. The main advantage of RFID technology is the automated identification and data capture that promises wholesale changes across a broad spectrum of business activities and aims to reduce the cost of the already used systems such as bar codes.
RFID Benefits in Inventory Management
RFID tagging for stock control offers several advantages over other methods such as barcodes, such as:
- Tags can be read remotely, often at a distance of several metres.
- Several tags can be read at once, enabling an entire pallet-load of products to be checked simultaneously.
- Tags can be given unique identification codes, so that individual products can be tracked.
- Certain types of tag can be overwritten, enabling information about items to be updated, for example when they are moved from one part of a factory to another.
RFID tagging helps:
- To prevent over-stocking or under-stocking a product or component.
- For stock security, by positioning tag-readers at points of high risk, such as exits, and causing them to trigger alarms.
- For quality control, particularly if you make or stock items with a limited shelf life.
An RFID tag is a tiny microchip, plus a small aerial, which can contain a range of digital information about a particular item. Tags are encapsulated in plastic, paper or similar material, and fixed to the product or its packaging, to a pallet or container, or even to a van or delivery truck. The tag is interrogated by an RFID reader which transmits and receives radio signals to and from the tag. The information that the reader collects is collated and processed using special computer software. Readers can be placed at different positions within a factory or warehouse to show when goods are moved.
With more and more emphasis on the real time tractability of personnel, goods, stock and vehicle; RFID (Radio Frequency Identification) technology along with IoT is redefining the business processes across supply chains. For successful RFID solution implementation every organization needs the right technology partner.

RFID systems are composed of three main components:
(a) RFID Tags
(c) Application System
RFID tags: also known as transponders (transmitter/responder), are attached to the objects to count or identify. Tags could be either active or passive. Active tags are those that have partly or fully battery powered, have the capability to communicate with other tags, and can initiate a dialogue of their own with the tag reader. Passive tags, on the other hand, do not need any internal power source but are powered up by the tag reader. Tags consist mainly of a coiled antenna and a microchip, with the main purpose of storing data.
Reader: also known as transceiver (transmitter/receiver) made up of a radio frequency interface (RFI) module and control unit. Its main functions are to activate the tags, structure the communication sequence with the tag, and transfer data between the application software and tags.
Application system: also called data processing system, which can be an application or database, depending on the application. The application software initiates all readers and tags activities. RFID provides a quick, flexible, and reliable way for electronically detecting, tracking and controlling a variety of items. RFID systems use radio transmissions to send energy to a RFID tag while the tag emits a unique identification code back to a data collection reader linked to an information management system. The data collected from the tag can then be sent either directly to a host computer, or stored in a portable reader and up-loaded later to the host computer.
