Qpass
Qpass of Seattle, WA was a technology company that specialized in providing the infrastructure for electronic payments. Examples are selling products through mobile phones, digital television and for billing services for Voice over IP products.
Prior to the dot-com boom Qpass handled billing of small web purchases such as buying an archived article from the New York Times website. The company nearly collapsed with the dot-com bust and re-invented itself as a company that works for providers in the mobile sector where premium content is still seen as a viable market.
