The NFC Forum is a non-profit industry organization comprised of business that span the entire NFC ecosystem. The NFC Forum’s primary purpose is to define a set of interoperability standards for NFC tags, devices and applications. Beyond standards, the NFC Forum encourages the usage and development of NFC, provides educational content and compliance tests.
The NFC Forum created it’s own trademarked logo to visually identify NFC tags, devices and applications called the N-Mark. Usage of this logo is governed by the NFC Forum.
The N-Mark is not often used for NFC projects as it is generally considered to not be a good logo, with too many similarities to the Bluetooth logo and the Nespresso logo.
