NFC chips are small devices that use radio waves to communicate with other devices over short distances. They are used in a variety of applications, including contactless payments, access control, data sharing, product tagging, and IoT devices.

The distinctiveness of these NFC chips lies in their authentication process. When scanned, the unique identifier (UID) and a special key undergo server verification to confirm issuance by the associated brand or company. This secure authentication enables exclusive access to specific webpages or content for users who scan the designated chip. This technology presents numerous opportunities, including verifying the authenticity of merchandise from specific brands.
