library, and your users are thankful. But how
about power for recharging their wireless devices?
Do they have to carry a cord and sit by the wall
so they can plug in? Restaurants and coffee shops,
the other popular places for public Wi-Fi, are
increasingly providing wireless recharging
stations at their tables, so users can simply lay
their smartphones on a charging pad and load up on
power. But nothing new is ever simple, and there
are competing technologies for wireless charging
at the moment. Recent news may make the choice of
charging equipment a little easier for everyone.

for Wireless Power merges with Power Matters
Alliance to push wireless charging standard</a>
(FierceWireless | Mike Dano) "The A4WP was
founded in 2012 to push the Rezence-branded
technology for magnetic resonance wireless
charging, and it counts Broadcom, Intel,
Qualcomm, Samsung and others as members. The PMA
was founded in 2012 to push its inductive
charging technology, and its backers include
AT&T, Duracell, Powermat Technologies and
Starbucks, which has added PMA-capable chargers
into some of its coffee stores. The groups said
they would now jointly push wireless charging
due to the merger, but that both technologies
would continue to be available so that members
could use whichever made the most sense."</li>

that they were moving closer together.
Meanwhile, the third group-called the Wireless

Philips and Microsoft. It supports a standard
called Qi (pronounced 'chee'), which it says
combines elements of both inductive and

merger wouldn't have an effect on its efforts to
bring wireless charging capabilities to the
