1. Anti counterfeiting performance ·QR code: Generate a unique anti-counterfeiting code for each product, but the QR code exists in the form of an image and is more susceptible to forgery through methods such as screenshots and remakes.
1. Anti counterfeiting performance
·QR code: Generate a unique anti-counterfeiting code for each product, but the QR code exists in the form of an image and is more susceptible to forgery through methods such as screenshots and remakes.
·NFC: It adopts electronic chip level anti-counterfeiting, and the internal information of the chip is encrypted with high-strength algorithms, making it difficult to copy and forge.
2. Information storage
·QR code: Limited storage capacity, but rich product information can be displayed through a one-to-one code system.
·NFC: With a large storage capacity, it can store rich product information.
3. Interaction
·QR code: Use a mobile phone to scan the code for information inquiry and other operations.
·NFC: No need to scan code, direct sensing through NFC function.
4. Durability
·QR code: Labels made of ordinary materials are prone to damage and moisture, making the QR code unrecognizable. Special materials need to be selected for special scenarios.
·NFC: Usually packaged in sturdy materials, it can withstand harsh environments such as high temperature, high humidity, and chemical corrosion.
5. Cost
·QR code: Low generation and printing costs, convenient for large-scale production and application.
·NFC: The chip cost is relatively high, with a wide price range for different performance.
6. Application scenarios
·QR code: widely used in various industries and products, with high adaptability.
·NFC: Suitable for scenarios that require high security, high interactivity, and durability.
