NFCmerkintö

NFCmerkintö is a Finnish term that translates to "NFC tag" or "NFC marking" in English. It refers to a physical object embedded with an Near Field Communication (NFC) chip. These tags are designed to be read by NFC-enabled devices, such as smartphones or dedicated readers, when brought into close proximity, typically within a few centimeters.

The primary function of an NFCmerkintö is to store and transmit small amounts of data wirelessly. This data can trigger various actions on the reading device. Common applications include storing URLs, contact information (vCards), Wi-Fi network credentials, or commands to initiate specific app functions. For instance, an NFCmerkintö placed on a poster could link directly to a website when scanned, or one at a transit stop could display real-time arrival information.

NFCmerkintö are widely used for convenience and automation. They are often found in marketing materials, product packaging, access control systems, and for personal automation tasks. The technology is passive, meaning the tags themselves do not require a power source, drawing energy from the reader's radio field to transmit their data. The simplicity and low cost of NFC tags make them a versatile tool for various interactive and informational purposes.
