McDonald's (MCD) is killing it in the U.S. -- but needs a little work in Asia.

Look at the company's February sales. The U.S. saw sales growth of 11% -- far more than what analysts expected. Sales in Europe rose 4%, still respectable but a little lower than what analysts were looking for.

But Asia and other parts of the world were a huge disappointment. Analysts projected an 8.1% rise, but McDonald's only came in at 2.4% growth.

That's got to change. So McDonald's is rolling out a number of new initiatives to try to beef up sales.

In Japan, it's testing a service that will let people place orders and pay for their food with a swipe of their mobile phone. Customers order and pass their phone over a special reader device to pay. The whole process takes 30 seconds.

McDonald's says that cutting that processing time by just 1 second will save several millions of dollars a year in Japan, according to the Nikkei.

One analyst gives his take on the company's February sales in the following video. The company had weather problems in Japan in the month, he said, and the Chinese New Year holiday shifted into January. He seemed to dismiss the problems in Asia.

McDonald's has also rolled out a service that lets Japanese customers order from their car navigation systems and pay before arriving at drive-thru windows. The service works with the "Intel Transport System" that Japanese drivers already use to navigate the roads.

If the service is successful, McDonald's could extend the service to the U.K., which is getting lobbied to launch a network similar to the transport system in Japan, the Telegraph reports.

China is going to be the real test, and McDonald's will go head-to-head with Yum Brands (YUM), which owns Pizza Hut, KFC and Taco Bell. Yum already has a huge presence in China and is still rapidly expanding. Oh, and shares of Yum hit a 52-week high of $69.75 Tuesday.

McDonald's has more than 1,400 restaurants in China and wants to open 250 more this year, according to the Motley Fool.

McDonald's shares fell more than 3% earlier this month after the company missed some of those estimates for February sales. Shares still haven't recovered, and were trading Tuesday at $97.61. McDonald's shares have soared more than 32% in the last year.
