The results of this research showed an effect of perceived ease of use to perceived usefulness is 72,9% (R 2 = 0,531, t = 12,882) , the perceived ease of use to attitude toward using is 60,1% (R 2 = 0,702, t = 8,927) , the perceived usefulness to attitude toward using is 29,1% (R 2 = 0,702, t = 3,564) , the attitude toward using of behavioral intention to use is 74,1% (R 2 = 0,549, t = 14,778) , and the behavioral intention to use the system to actual system use is 36,2% (R 2 = 0,131, t = 4,603). This research proves that the user acceptance of a technology strongly influenced by perceived ease of use and perceived usefulness which are emerging acceptances and then behavior intention to use where as to reveal the using of a real system in the intensity of usage time
