Michael Arrington writes on his TechCrunch blog about mobile payments provider KushCash - asking them how they plan to compete with PayPal Mobile, among others.

Red Herring takes a look at KushCash (see earlier announcement article) and several other companies also active in the US mobile payments space. The article quotes Julie Ask, a wireless analyst at JupiterResearch, who says “I think what needs to happen is that there needs to be a compelling reason for why I want this. What are the scenarios that I need to be traveling so lightly that I don’t need to take my wallet with me?”

Secure Wireless Transfers Corporation has announced KushCash, described as "a secure, alternative payment system to traditional methods for instant, easily accessible cash transactions from anywhere-at events, retail malls, public locations, in transit, or on campus."
