Scope Of RFID Systems In Security Measures

What is RFID?

Radio-frequency identification device is a technology that retrieves the status and presence of a thing to which it is attached to remotely. These devices will track the objects automatically and sends the embedded information to the processors.

Typical components of RFID system

An RFID system contains an RFID tag, RFID reader, RFID antenna, and RFID package.

RFID tag is attached to the item that needs to be tracked and identified.

RFID antenna will detect the RFID tag when it comes in range.

RFID reader reads the RFID tags and authenticates its presence.

RFID package contains the server and software and transmits the information to all other applications.

Application of RFID systems

To simplify, RFID systems do the same function as of a BAR-CODES, but when it comes to applications they are widely spread as RFID systems doesn’t need to maintain contact with the scanners as in case of BAR-CODE. High Frequency RFID systems doesn’t necessarily to be appear in the line of sight, especially such are applied for live stock tracking, Missile tracking, automobile tracking through assembly lines and most importantly in case of vehicle tracking.

Security potential

Increasing security measures through CCTV cameras has already outdated, the latest technology implies to the usage of RFID readers wherever the security is needed along with authentication.

They can be installed in a library, home, and elsewhere domestically to secure the important files, books, and expensive things, so that even when they are found missing they can be easily detected with the help of local servers that are giving location information.

They can also be placed in a vehicle, thanks to their non-contact readable characteristic feature as the vehicles can be tracked along the route as they can use the location provided by the nearest GSM signal boosting towers and thus one can keep notice of their vehicles.

The size of the smallest developed RFID is 0.05mm × 0.05mm size and the average size would be around 3mm x 3mm. As we go cheaper the size will be increased consistently. Their dimensions make them invisible to see which a plus point in terms of security measures is.

As we go on, the list will be huge and if you’re interested you can search more on the web. I wrote this article to give a brief information in a simple manner as I thought many readers will find it hard to know about the RFID technology due to the complex words involved in.
