NFC and QR Codes are considered as the most effective options for security guard management. These codes enable you and your clients to know the exact location where your officers are when they scan an NFC or QR code at an assortment of checkpoints on their guard tour. The scans tags can be positioned on any locations and assets to get real-time information about incidents and actions. At any time you can scan these QR-code or NFC tags and later the information is sent to the web application via a cloud server and you can access it anytime and anywhere in the world. However, the guard tour system can scan an NFC and a QR tag that works on Android, iPhone, Windows phone or any smart devices. Eager to know more about the difference between NFC and OR codes, let us briefly take a look into it and the benefits it has to offer.
QR-Codes (Quick Response Codes)
QR-Code is an acronym for Quick Response Codes. It is a mobile phone readable two-dimensional barcode that is encoded with data both in vertical and horizontal directions and contains more than 2000 characters that can be read using a simple cell phone with a camera. The information of QR code is encoded in the form of alphanumeric, binary, numeric & kanji (Japanese word). It’s made up of black segments that are well- structured in a square grid on a white background. The QR can store much data and can read by only visualizing device and it can be refined by error modification until the image will be construed adequately. QR Codes are used today in everything from inventory tracking, making online payments, shipping and logistics, to tracking guards, everyone is using them as a part of security patrolling systems.
Benefits of using QR-Codes as Checkpoints in Guard Tours
Additional Flexibility
Easy To Use – It can be effortlessly assigned to a location/site
Minimal cost
Simple point assignment
By increasing QR-code sizes you can gain larger functionality distance ranges
You don’t have to worry anymore about the surroundings interference concerns.
NFC – (Near Field Communication)
NFC stands for Near Field Communication. It’s a short-range wireless technology that allows users to communicate between two or more devices when they are in clear LOS (i.e., Line of Sight) of each other and separated by a few centimeters. The devices using NFC can be passive or active, whereas the passive device has an NFC tag that consists of data that other devices can read but it can’t read any information itself. While, an active NFC device would not be able to collect information from NFC tags, but it can exchange information with other companionable phones or devices. The NFC tags have tiny microchips with aerials that help you to transfer data to another NFC device, such as a smartphone.
