NFCmerkkejä

NFCmerkkejä, often translated as NFC tags or NFC labels, are small, passive devices that can store and transmit data wirelessly using Near Field Communication (NFC) technology. These tags do not have their own power source; they are energized by the radio frequency field emitted by an NFC reader, such as a smartphone. When an NFC-enabled device comes within a few centimeters of an NFCmerkki, the tag can be read or programmed.

The data stored on an NFCmerkki can vary widely depending on its type and intended use. Common applications include storing URLs to websites, contact information (vCards), Wi-Fi network credentials, simple text messages, or commands to trigger specific actions on a device. For instance, tapping an NFCmerkki with a smartphone could automatically connect to a Wi-Fi network, open a specific application, or send a pre-written text message.

NFCmerkkejä are typically made of flexible plastic or durable materials and often come with an adhesive backing for easy placement. They are frequently used for marketing promotions, enabling quick access to product information or special offers, and for automation tasks in smart homes or offices. The simplicity of use, requiring only a tap from an NFC-enabled device, makes them a convenient tool for various interactive applications.
