What's a company in the overheated mobile POS market to do when a competitor is down? Why, kick them, of course.

Following the announcement by Swedish mobile POS company iZettle that it can no longer process Visa payments in Nordic countries, its competitor mPowa released a press statement calling the news a "a major restriction" and touted the new Android version of its solution.

Like iZettle, and unlike many rival U.S. mobile POS companies, mPowa offers merchants the ability to process both chip-and-PIN and mag stripe cards. Based in the U.K., mPowa recently entered the U.S. market. It took the occasion of announcing its new Android release to draw attention to iZettle's setback.

"With mPowa, we are allowing businesses everywhere, from the smallest to the largest, to take payments wherever business is transacted," said Dan Wagner, CEO and founder of mPowa. "MPowa is the first to offer such an innovative and exciting mobile payment solution for Android. The device accepts all major credit and debit cards including Visa, MasterCard and American Express."

"The recent extension to Android shows that mPowa is a truly universal way of making and accepting mobile payments, unlimited by geography, card issuer, operating system, device, currency or method of verification," Wagner said.

MPowa was recently involved in another spat with mobile POS rival Square. The company received a cease-and-desist notification from Square regarding a very similar image it used on its website. MPowa has since removed the offending image.
