RFID in Asset/Inventory

Asset Tracking consists of identifying and tracking the movement of physical assets and equipment within a location as well as their incoming and outgoing movement to and from the workplace. Inventory Control is a process that manages the quantity of stock and tracks its movement through warehouse, manufacturing and supply chain. It applies to every item from raw materials to work-in-process to finished goods and covers every stage from purchase to delivery.

Management of assets and stock inventory is a complex task that faces several challenges. Lack of visibility regarding differentiation, location, movement and usage is the most common and also the most critical challenge in inventory tracking. This causes errors, misplacement, lost time, additional manpower requirement and maintaining duplicate inventory, resulting in higher cost of inventory management. Shrinkage due to lost assets, theft, expired stock and non-compliance is another factor that impacts business. Scheduling, life-cycle management and audit trail are other areas that suffer due to inefficiency in asset and stock control.

Efficient asset and stock inventory management requires the availability of the right item in the right quantity in the right place at the right time. Conventional tracking methods such as barcodes have distance constraints, require manual positioning within line of sight and can get easily damaged. Besides, they do not ensure that inventory is accurate and up-to-date. RFID offers the only assured solution that provides real-time automated tracking, ensuring total visibility and highest accuracy. RFID based real-time tracking results in real-time data and instant decision making on asset allocation, inventory levels, reorders and storage management.

RFID tagging of inventory enables each individual item or component to be allocated unique identification and be uniquely tracked throughout the production and distribution supply chain. RFID readers are placed at various locations within a factory or warehouse and at entry/exit gates. They continuously read tags that are within range and send this data back to the controlling system. Data associated with each unique tag gets easily updated on the server when the tagged items are moved from one location to another. RFID has no line of sight requirements since the tags can be read remotely over a considerable distance. Unlike barcodes, multiple tags can also be read simultaneously, enabling full shelf-loads or pallet-loads to be tracked at once. There is also no stoppage in movement flow since the tags can be read on the move as items pass through a portal that has mounted RFID readers.

Deploying RFID in asset and stock inventory enables maintenance of reduced inventory levels and just-in-time delivery scheduling. It provides improved batch control, better process control, accurate component management and maximum asset utilization. It enables automated reordering and reduces order lead-time. It improves shelf availability and speeds pickup in the warehouse. RFID significantly improves security through automated tracking and alarm triggers at exits, and also improves quality control through inventory history, automated shelf-life monitoring of items and asset life-cycle management. Improved asset and stock inventory management through RFID ensures that excess capital is not tied up and that there are further savings in time and labour utilized. RFID is a reliable, efficient and cost-effective method of tracking goods and assets for manufacturers, suppliers and distributors. It is being increasingly deployed by more and more enterprises as a transformational technology for the modern business world.

Class 0 UHFl read-only, preprogrammed passive tag
Class 1 UHF or HF; write once, read many (WORM)
Class 2 Passive read-write tags that can be written to at any point in the supply chain
Class 3 Read-write with onboard sensors capable of recording parameters like temperature, pressure, and motion; can be semipassive or active
Class 4 Read-write active tags with integrated transmitters; can communicate with other tags and readers
Class 5 Similar to Class 4 tags but with additional functionality; can provide power to other tags and communicate with devices other than readers

(Class-1 Gen-2 RFID tags are backward-compatible with Gen-1 Class-0 and Class 1 tags.)

Types of RFID

RFID products fall into two basic categories: Passive and Active. Passive tags do not have batteries and have indefinite life expectancies. Active Tags are powered by batteries and either have to be recharged, have their batteries replaced or be disposed of when the batteries fail.

RFID products are then broken up into different frequencies. Tags and Antennas are tuned or matched much the same way as a radio is tuned to a frequency to receive different channels. These frequencies are grouped into Four basic ranges: Low Frequency, High Frequency, Very High Frequency and Ultra-High Frequencies.

LF: low Frequency range:30KHZ-300KHZ;RFID USES:125KHZ
HF: HIGH Frequency range:3MHZ-30MHZ;RFID USES:13.56MHZ
VHF: VERY HIGH Frequency range:30MHZ-300MHZ;RFID USES:Not used for rfid
UHF: ULTRA HIGH Frequency range:300MHZ-3GHZ;RFID USES:868MHZ,915MHZ

Each frequency range has its advantages and disadvantages. Europe use 868 MHz. for its UHF applications while the US uses 915 MHz. for its UHF applications. Japan does not allow the use of the UHF frequency for RFID applications. Low Frequency tags (LF) are less costly to manufacturer than Ultra High Frequency (UHF) tags. UHF tags offer better read/write range and can transfer data faster then other tags. HF tags work best at close range but are more effective at penetrating non-metal objects especially objects with high water content.

Once a frequency range is determined, then it is time to choose an antenna that best fits the application. Antennas come in all sorts of sizes and shapes. The size of the antenna determines the range of the application. Large antennas used with Active Tags can have a range of 100 feet or more. Large antennas used with Passive Tags generally have a range of 10 feet of less. There are dock door antennas (some times called Portals) that allow a forklift driver to drive between two antennas. Information can be collected from the tags without the forklift driver having to stop. There are antennas that mount between rollers on conveyors for reading/writing from below. While other antennas are available that mount to the side of or above the conveyors. Handheld Reader/Writers are available as well.

Controllers are available to communicate with most Networks (Ethernet, DeviceNet, ProFibus, etc). They typically have serial ports for programming and data transfer. Controllers are usually shipped with programming software to set-up and customize the application. Controllers typically operate on 120VAC or 24VDC.

Do You Know the Modern Method to Get Information from Animals Ear Tag?

Humans have been using brands to recognize livestock animals for hundreds of years. In prehistoric times it was more of a ritualistic act. During the middle Ages in Europe, hot branding was used to identify the owner of livestock. This has sustained all the way through history. In the American West branding is often associated with trail drives and cattle rustlers. Electronic animal identification is a significant technology in contemporary animal husbandry offering immense benefits. Low-frequency applications are high-tech within the radio frequency classification of animals.

Ultra-high-frequency (UHF) submissions are appropriate for this purpose. Still, UHF systems have inadequacies through their defenselessness to metallic surfaces and liquids. Therefore, the reflection and amalgamation of electromagnetic radiation in the animals’ environment is often challenging. Modern farming techniques dictate careful and accurate control of livestock, including the skill to tell apart individual animals. Livestock ear or recognition tags have been generally used to identify livestock for centuries. The use of identification tags has led to vast improvements in competence in agricultural industries, in addition to enhanced safety and lower costs to consumers because disease and genetic mutations are more easily identified with each improvement in the tracking of livestock.

There are many types of identification devices in use, such as rings, tattoos, and identification tags. The concluding ones are attached to the ear of the animal. Normally they include inkjet or laser markings which recognize, for example, the animal on top of the location where it was raised. EID tags are small “button-like” tags that are positioned in the ear. Each EID tag has an exclusive 15-digit number printed on it, and the number can also be read by scanning the tag with an EID reader. These tags are intended to last for the life of the animal. RFID’s are commonly exploited for electronically identifying animals or objects. In many submissions, the transponder unit is laden with data and attached to an animal or object which is to be recognized.

An excellent application of non-powered RFID system is revealed for identification of animals in a meat-processing place. The reason for identifying individual animals in a meat-processing plant is for safety and sterilization reasons, and to perk up the meat quality and farming methods.

An Animal ear tag typically carries an Animal Identification Number (AIN) or code for the particular animal or for its herd or flock which helps in tracing and finding the animal and to know the detailed information about the animal.
