How Lightning Tightens Apple\'s Control Over Accessories

When the iPhone 5 was released in September with the new Lightning connection port, all those docks and accessories that longtime Apple customers had been collecting for years were suddenly obsolete. But Lightning-compatible accessories have been trickling in more slowly than the typical flood of Apple accessories that comes after a new iPhone release. Why

One challenge, according to a person briefed on Apple’s plans who was not approved to discuss them publicly, is that the iPhone 5 is more fundamentally different from previous versions of the device than new models usually are  â€" introducing a different overall size and shape as well as an engineering change. At the same time, with Lightning, Apple has made it harder for companies to avoid working with its own licensing program. Both of these factors have slowed the production of accessories.

Mophie, an accessory maker, hared some insight into Lightning and the overall process of making an Apple accessory. (This week it introduced the Helium, its first iPhone 5 case with a backup battery.) When a hardware maker signs up with Apple’s MFi Program, for companies that make accessories for Apple products, it orders a Lightning connector component from Apple to use in designing the accessory. The connectors have serial numbers for each accessory maker, and they contain authentication chips that communicate with the phones. When the company submits its accessory to Apple for testing, Apple can recognize the serial number.

“If you took this apart and put it in another product and Apple got a hold of it, they’d be able to see it’s from Mophie’s batch of ! Lightning connectors,” said Ross Howe, vice president of marketing for Mophie.

The chip inside the Lightning connector can be reverse engineered â€" copied by another company â€" but it probably would not work as well as one that came from Apple, Mr. Howe said. Apple could also theoretically issue software updates that would disable Lightning products that did not use its chips, he said.

What’s the benefit for Apple The proprietary chip makes it more difficult for accessory makers to produce cheap knockoff products that are compatible with Lightning, which could potentially tarnish the iPhone brand. Also, it pushes accessory makers to pay Apple the licensing fees to be part of the MFi program.

“That’s one thing Apple is good at: controlling the user experience from end to end,” Mr. Howe said. “If you’re buying something in an Apple store, it’s gone through all this rigorous testing.”
