RFID technology is finding its way to the law. Radiofrequency identification is generally used for asset tracking and asset management purposes. Even its commercial success is related to Kevin Ashton using it for retail business to tackle the ‘out of stock’ problems in retail, which, believe me, is a far bigger problem than we all know. However, Kolkata police have found a new way to use the RFID technology.
Recently Kolkata police asked all the cops on outside/patrol duty to swipe their RFID cards on a tablet to record their outdoor duty attendance. Keeping track of which cop is posted in which area at any time of the night or day is crucial to cop duties and management as such. And RFID is the perfect solution for this outdoor attendance tracking requirement as it allows for accurate identification and tracking of employee attendance, and their movement with the help of a software system designed for the same.
Know About RFID Technology
Radio Frequency Identification or RFID is an AIDC (Automatic Identification and Data Capture) technology that is now a commercial success due to retail item-level tracking and inventory management applications. It is heavily used by retail businesses to manage the supply chains and logistics part of their business and ensure 360-item inventory visibility and timely delivery of orders, known as order fulfillment.
RFID technology uses RFID tags, RFID readers, RFID antennae, and a software system as primary components. The RFID tag is a small electronic label/ plastic tag that has a microchip or integrated circuit attached to an antenna (lines). The microchip holds the data about the item being tagged with the RFID label.
An RFID reader is a slightly bigger and heavier device, which sometimes has a smartphone attached to it (RFID SLED Readers), and it is used to interrogate the RFID tags in the vicinity, capturing data from the tags automatically, one by one.
The RFID antenna facilitates this communication between the RFID reader and the RFID tags. It boosts signals and provides range. An RFID software system is used to store the information and process the data for better insights for the end users.
How this RFID-based Attendance System Work?
The RFID-based attendance system as proposed here uses RFID High Frequency based smart cards and smartphone/tablet as provided to the cops on outdoor duty in Kolkata.
HF RFID system works on HF, 13.56MHz frequency, and follows the ISO/IEC 18000-63 EPCGlobal Gen2v2 communication. The RFID system is compatible with the NFC feature found in smartphones and tablets allowing individual RFID cards to be read by a tablet. Geo-location of the Android devices/tablet ensures that the RFID card is only swiped by a cop on duty, at the designated area.
The RFID PVC cards allotted to each cop would be tamper-proof and contain the identification of the cop. On swiping the card with the tab, the attendance of the cop will be automatically updated on the software system, designed for this purpose.
The RFID card automatic attendance system will result in several advantages for the Kolkata police force, one of them being orderly management of cop duties during nighttime and emergencies. It will ensure that the police department has a real-time picture of cops posted outside, allowing for their movement monitoring. It will also help streamline their attendance and benefit citizens in the long run.
