Nike NFC tag is a small electronic chip that uses Near Field Communication (NFC) technology to communicate with smartphones and other compatible devices. The tag is embedded in certain Nike products, such as shoes and apparel, and allows users to access exclusive content, personalized experiences, and other features through the Nike app.

When a user taps their NFC-enabled device on the Nike NFC tag, the chip sends a signal to the device, which triggers a response from the Nike app. Depending on the product, the content that is accessed can include things like workout recommendations, training programs, product information, and even virtual try-ons of new products.
Nike NFC tags are part of Nike's larger strategy to integrate technology into their products and create more personalized experiences for their customers.
