Ready to reveal secrets of Apple’s MFI Lightning connector chips! So, lets begin.

What is Apple MFI Certification?

Apple firm’s MFi Program is known as “Made for iPhone/iPod/iPad”. It involves connectors including the original dock connector, Lightning Connector, the headphone jack. As well as AirPlay support. Companies joining the MFi program must go through certification tests and then have the rights to show MFi-related logos on their packages. The Apple MFI Program guarantees that the accessory you purchase has been tested and endorsed by Apple. Apple charged a 10% fee for products with the logo, which was referred to as a “tax” by the press. Licenses were available for products using the extended iPod headphone jack or the dock connector.

The rebranding came up along with the introduction of Lightning Connector as MFi, an informal term that was already in use. This new connection was equipped with other protocols which were not officially recognized unless they went through the MFi program. In addition, Apple updated the third party license agreement to obligate them in accepting its suppliers responsibility code.

MFi Certification Brief History.

The MFi (Made for iPhone/iPad/iPod) Certification Program has a significant history that traces its evolution alongside Apple’s iconic product line.
