QR code and blockchain technology are excellent systems used to transparently present the origin of food, from its ingredients to its production processes, by providing instant information to consumers and producers.
* Consumers can scan the QR code to find out where the product was manufactured and which farm or producer it came from.
* Provides detailed ingredient information for people with food allergies or special dietary requirements.
* Provides information on product freshness and shelf life.
* Certifications such as organic, halal, and vegan are verified via QR code.
* The entire process, from production to shelves, becomes transparent.
Some brands (such as Nestle and Unilever) are adding QR codes to their product packaging to provide consumers with more information and trust.
Unlike QR codes, blockchain offers a secure recording system against data manipulation. This prevents "food fraud," which is one of the most important issues, through blockchain technology.
* Every supply chain stage is recorded on the blockchain. No one can change this information or these records.
* If there is a problem with a food product (e.g., a bacterial outbreak), which batch number came from which farm is identified in seconds.
* Consumers can check the stages a product has gone through on the blockchain by scanning a QR code.
* Automatic agreements between producers, farmers, and retailers accelerate the supply process once initiated.
Blockchain technology has started to be adopted in Turkey and has application areas in various sectors. By integrating QR codes and blockchain technology, its use in food will be at much better points.
* Marketing advantages will be gained for products through transparency.
* Businesses will be more prepared for official inspections and exports.
* Stronger relationships will be established with business partners, providing greater trust and being significantly noticed by consumers.
