Here's a breakdown of how they work and what makes them "safe":

How QR Codes Work

A QR (Quick Response) code is a two-dimensional barcode that stores data in a square pattern of black and white squares. When you scan a QR code with a camera, the device's software interprets the pattern and translates it into a human-readable format. This data can be:

• A website URL
• Text

• Contact information

• Location data
• Payment details

Applying QR Codes for Safety

In a safety context, the encoded information is specifically designed to provide essential safety-related content. This can include:

• Emergency Procedures: A QR code in a building's hallway might link to an evacuation plan, fire extinguisher locations, or first-aid instructions.
   
• Equipment Manuals: Placing a QR code on a piece of machinery allows workers to instantly access operation manuals, safety guidelines, and maintenance logs, reducing the risk of misuse or accidents.
   
• Hazardous Materials: QR codes on chemical containers can link to Material Safety Data Sheets (MSDS), providing critical handling instructions, required Personal Protective Equipment (PPE), and emergency contact information.
   
• Inspections and Audits: QR codes can be used to track and manage inspections. A technician can scan a code on a piece of equipment to access its inspection history and complete a new checklist, ensuring data is accurate and up-to-date.

• Visitor Management: Unique QR codes can be used for contactless check-ins, enhancing security by ensuring only authorized individuals can enter a site.

Use NekInsan Safety QR Code

NekInsan is a company that provides safety solutions using QR codes on stickers and tags for various applications, including vehicles, children, and personal belongings. Their system is designed to facilitate quick communication in an emergency while protecting the privacy of the owner.

Here's a breakdown of how the Nekinsan safety QR code system works:

1. Purchase and Setup

• You purchase a Nekinsan QR code sticker or tag for a specific purpose (e.g., car, bike, child, keys).
   
• You register the unique QR code on the NekInsan platform, either through their app or website.
   
• During registration, you link the QR code to your profile and pre-register a list of emergency contacts (family, friends, etc.).
   
• You can also add other important information, such as medical details like allergies or blood type, although the primary function is communication.

   

2. The Trigger: Scanning the QR Code

• If an incident occurs (e.g., a car accident, a lost child, or a misplaced item), a helpful person (referred to as a "Nek Insan" or good Samaritan), a police officer, or a first responder can scan the QR code.
   
• The scan can be done with any standard QR code scanner, such as Google Lens, Paytm, GPay, or a smartphone's camera, without needing a special app.

3. The Immediate Response

• Instant Alert: The moment the QR code is scanned, an alert is sent to the owner of the item and their pre-registered emergency contacts.
   
• Siren Alert: This alert often includes a siren sound that plays on the emergency contacts' phones, even if the screen is locked, to ensure they don't miss the critical notification.
   
• Location and Context: The alert provides the date, time, and precise GPS location of where the scan occurred. The scanner is also prompted to capture and send a photo or video of the situation, which gives the emergency contacts valuable visual context (e.g., a photo of a car crash or a picture of a lost child).

4. Communication and Privacy

• Masked Calling: A key feature of the Nekinsan system is "call masking." When the alert is received, the system facilitates a call connection between the scanner and the owner's emergency contacts through a virtual number. This means neither party's actual phone number is revealed, protecting the privacy and security of both individuals.
   
• Callback Feature: The emergency contacts also receive a "Call Back" button, allowing them to reconnect with the person who scanned the QR code, still through the masked number, if needed.

• IVR Calling for Non-Smartphones: If the scanner doesn't have a smartphone or internet access, they can dial an IVR (Interactive Voice Response) helpline number and an extension number printed on the sticker to initiate the same alert process.

5. Accessing Emergency Services

• After the communication with the emergency contacts, the scanner's phone will often display a pop-up with local emergency helpline numbers (e.g., Police, Ambulance, Fire department), allowing them to quickly call for professional help.

While the system is primarily for emergencies, Nekinsan also applies it to non-critical situations:

• Wrong Parking: If a car is parked improperly, someone can scan the QR code to send an alert to the owner, allowing them to move the vehicle without revealing their contact information.
   

• Lost Items: For items like keys or luggage with a Nekinsan tag, the finder can scan the code to be connected with the owner, facilitating the item's return.
