This is Incorrect. Samsung has teamed up with PowerMat

Joining Powermat, Samsung and Qualcomm in the partnership are Ever Win Industries, Gill Industries, Peiker Acustic, and SK Telecom.

Global Technology Power Players Unite to Form Alliance for Wireless Power Creating Spatial Freedom in Consumer Electronics Charging

May 7, 2012 Announcements, Press Releases

Wireless technology leaders Samsung and Qualcomm Incorporated have joined other technology leaders including Powermat Technologies to form the Alliance for Wireless Power (A4WP).

PowerMat was QI Standard, they have teamed up with Samsung and others to form Alliance for Wireless....

This why the new battery covers aren't out yet and was delayed by Samsung in the beginning....The old/current covers you get get now will work with Powermat, I have bought 7 of them from Amazon each under $3.00 ....the new covers will be different...

CONCLUSION

The study showed the novel construction is a good

candidate for a wireless power system with arbitrarily large

spatial freedom that satisfies the efficiency requirements as

specified by the Qi standard. This construction allows for

benefits of efficiency, protection from transfer of energy into

unwanted subsystems, and standardization for commercial use

due to a closely aligned WPS. It also allows an experience of

spatial freedom that enhances usability, and simplifies

implementation due to the coil constructs and the relatively

simple control circuitry. In addition, it covers more area per

given coil than other proposed coil arrays in the present Qi.

Verizons phones are the only models that have the extra contacts, all others just have the two and still have the NFC hardware and Antenna in the Battery...Prob because Samsung is going to the new Standard that can charge without being in a perfect spot on a charger, Called Spartial Freedom and Verizon wanted the two sets so they could continue to sell one charger and make more money. Causing the phone to need more purchases to upgrade to the newer charger coming out soon.

WPC products carry the distinctive Qi logo; Qi is a play on the Chinese word for energy. The WPC has already built up a strong ecosystem in Japan, where NTT Docomo has sold a million Qi-enabled phones from four manufacturers. The story in the U.S. has been very different. Here, only a handful of compatible phones have been released in the last year from HTC, LG, Motorola, and Samsung, and all of them are on Verizon. We haven't seen much activity stateside since Verizon launched the Motorola Droid 4 earlier this year. That model had an optional, extra-cost battery door with Qi built-in.

Then there's the Alliance for Wireless Power (A4WP), which launched at CTIA in May and counts wireless giants Qualcomm and Samsung as active backers. The A4WP approach uses resonance charging to give spatial freedom between where you place a device on a charging surface and where the wireless transmitter sits inside the charging surface. In other words, once you place a device anywhere on this type of charging surface you’re good—there’s no need to aim for a target.

Samsung could not comment as to when it might bring a product to market, but a company spokesperson did note that the wireless charging accessory that's part of its Galaxy S3 released in May “uses the basic technology” that's promoted by the A4WP. A Samsung spokesperson said that the Galaxy S3 implementation “is a good indication that the technology is mature and products with the A4WP specification are not far off.”

Somewhere in between these two is Duracell Powermat, which participates in the A4WP as well as the Power Matters Alliance. Power Matters' role is to push “Power 2.0,” a group that's trying to promote industry standards with its own logo program. Meanwhile, Powermat has partnered with Duracell to market its own inductive-power phone-charging sleeves and mats. At the moment, what's available is focused on adding wireless inductive charging to existing phones via cases rather than integrating the technology inside the devices. Powermat has demonstrated a wireless charging card that can be added into a device, but we haven't seen any products ship that have this technology built inside.
