QR CODE
WHY IN NEWS?
- The Food Safety and Standards Authority of India (FSSAI) has recommended the inclusion of a QR code on food products for accessibility by visually impaired individuals.
WHAT IS QR CODE ?
- A QR code (short for Quick Response code) is an array of black and white squares or pixels set in a grid that stores data for a machine to read.
- A smartphone or camera can quickly process the information contained in a QR code’s specific arrangement of pixels.
APPLICATIONS OF QR-CODE:
QR codes can be used to:
- View a menu in a restaurant.
- Get directions to a location in Google Maps.
- Read more about a product or service.
- Download an app on the App Store or Google Play.
- Authenticate an online account.
- Verify login details.
- Access Wi-Fi by storing SSID, password, and encryption type.
- Send and receive payment information.
HOW DOES QR CODE WORK?
- QR codes work by arranging a series of black and white pixels into a unique pattern that encodes a string of data.
- When scanned, the pattern of the qcode can be translated into human-readable information.
- QR codes can store much more data, because they’re written both vertically and horizontally.
- An active QR Code is one that a QR Code scanner is able to scan easily, prompting users to click on an external link upon scanning.
- The external link delivers relevant information that the user is looking for.
INFORMATION STORED IN NEW FSSAI QR CODE:
- The FSSAI has advised that these new QR codes should encompass comprehensive details about the product, including ingredients, nutritional information, allergens, manufacturing date, best before/expiry/use by date, allergen warning, and contact information for customer enquiries.
- The inclusion of a QR code for the accessibility of information does not replace or negate the requirement to provide mandatory information on the product label, as prescribed by relevant regulations.
