NADCA | Digital Smart Logo

Digital Badge Installation Guide


The National Air Duct Cleaners Association (NADCA) has partnered with Yoshki Ltd to develop a secure digital badge using the Yoshki Digital Smart Logo service.

The NADCA digital badge will allow members of the public to easily identify that a website they are visiting belongs to a genuine NADCA Member. It will also provide visitors with easy access to information on the company’s membership details.

Thanks to the software through which the badge is provided, only NADCA authorized websites can use the digital badge.
