MFi Program

Companies joining the MFi program and passing certification tests are able to display certain MFi-related logos on their product packaging, like the "Made for iPod" badge.

[4] These signals are used by many Made for iPod devices to allow remote control, including car integration systems.

AirTunes was originally introduced in 2004 on the Mac and PC platforms inside iTunes,[7] and later became known as AirPlay when video-out capabilities were added to support devices like the Apple TV.

With the introduction of the Lightning connector, the branding was changed and officially became MFi, a term that had been used unofficially for some time.

[9] Developers wishing to integrate their devices and application with HomeKit must also be members of the MFi program in order to get access to specifications, as well as certify their products.

The modern Made for iPod logo is typical of the MFi program badging.
