Verifone went public in March 1990, raising more than $54 million. As the credit card industry matured, Verifone pushed to install its systems into new markets, such as restaurants, movie theaters, and taxis, as while as developing software capacity to bring its systems into the health care and health insurance markets and to government functions. International sales also began to build, as use of credit cards became increasingly accepted in foreign markets. VeriFone was also building its global operation, opening facilities in Bangalore, Singapore, England, Dallas, and Ft. Lauderdale, in addition to its Hawaii and California facilities. Rolling out its Gemstone line of transaction systems, which added inventory control, pricing, and other capabilities, Verifone was aided by announcements from Visa and MasterCard that the companies would no longer provide printed warning bulletins, while requiring merchants to seek authorization for all credit card transactions by 1994.
