intention to use was chosen as the main indicator of IS acceptance in

[29–32]. User satisfaction, which has been defined as the extent to
which users judge that the attributes of an information system match
their needs and expectations[33], has been found to be a key measure
of success[34].
In the TAM, perceived usefulness and perceived ease of use are the

the following hypotheses:
