RFID is a system consisting of tiny radio transmitters. It comprises radio waves receivers and transmitters. It consists of devices that use electromagnetic waves. It is used to identify and track tags attached to objects. Tags used in this technology are RFID tags in which we store data. We send and receive data through this system. It consists of RFID tags, an antenna, an RFID reader, and a transceiver.
RFID has revolutionized many industries. One out of them is asset management. Asset management is important as well as complex.
It has characteristics such as:
- Large quantities
- Many kinds
- High value
- Long use cycle
Due to this, it has become more difficult to manage assets. And RFID for asset management has solved all the problems perfectly.
It is a system that identifies the targeted object and obtains required data using RF signals.
It is a system of tracking tags to automate, manage and locate processes of physical assets. The RFID tag is loaded with data and attached to relevant assets. Data includes everything from names, conditions, amount to location.
A company’s assets are actually the largest investment in any business. The challenge is not only to track their whereabouts but also to make sure that they are inspected and maintained regularly from time to time. RFID offers an effective way to manage and track your valuable assets by allowing you to automate your processes and reduce costs.
RFID permits you to check singular things using RFID labels appended to them. Fixed scanners scan the tags which are present on entryways and other central gates or by staff utilizing cell phones or tablets.
This system can screen things leaving or getting back to the site. RFID scanners can upgrade wellbeing and security necessities by overseeing administration. It also improves responsibility by checking which staff checked a specific thing and on what date. An RFID asset management system must have the following qualities.
- Tracking many assets at one time.
- Eliminating human intervention.
- Collecting data in real-time.
- Improving asset visibility.
- Locating lost or misplaced assets.
- Maximizing accuracy of inventory
RFID for asset management provides a lot of advantages over barcode readers:
- Reading many tags at once. One employee can check an entire room full of assets in minutes.
- Critical information about them can be stored on assets themselves.
- Tags are integrated with sensors and GPS which give condition and location information.
- Productivity is enhanced because assets can be located almost instantly
- If we integrate the System with wireless LAN assets can be identified remotely in seconds.
- Inventory times can be reduced from days to hours.
- Setup of alarms improves security. It alerts if assets are taken out of the building or taken to unallowed locations.
Tags are usually of two types generally:
Passive tags and Active tags
Passive tags are one of two general categories. They are smaller and less expensive than active tags, so their read ranges are shorter. Passive RFID tags have no power of their own. They get power from radiofrequency energy which transmits from antennas. The signals of the reader and antenna give power to the tag and reflect the energy to the reader.
Active tags are the second of the two general categories. They are typically larger and more expensive than passive tags. They offer longer read ranges as in some cases can extend up to 10Active tags. It can often support sensors that measure conditions like temperature, light, and humidity. This makes them popular in harsher environments. They are typically used to track larger assets like vehicles and cargo. But, active tags typically have a more limited lifespan than passive tags.
