The study has also sought to evaluate this impact through satisfaction indicators, and whether there are differences between the studied sample members’ averages about the role of E-payment methods in improving the quality of the postal financial service, according to demographic variables. The study has been carried out, according to the descriptive-analytical method. Data and preliminary sources have been collected via a survey designed specifically to fit the study case. The study has been conducted on a non-probable sample consisting of (372) customers for geographical areas that have been subjected to probable withdrawal, corresponding to the cluster stratified sample, representing (15) administrative districts in M’sila state, so that the total number of withdrawn areas (clusters) is fifteen (15) administrative districts. We’ve presented this withdrawal again for the municipalities belonging to these districts, which resulted in ten (10) withdrawn municipalities belonging to five (05) administrative districts that have been included in this study. The Statistical Package for Social Sciences (SPSS V26) has been used to conduct several statistical analyses in the applied chapter. The attained results have shown that there’s a positive impact of the perceived quality of E- payment services on the postal financial service quality. They’ve also shown the availability of all dimensions of service quality of the model used in varying degrees. The dimension of (security) ranks first with an average of (3.83), whereas the dimension of tangibility ranks second, with an average of (3.58). The study has also revealed a positive impact of the perceived quality of E- payment services on the postal financial service quality through the satisfaction indicators, as these indicators have been evaluated by the sample members with a high degree of (3.75). The results have also shown that there’s no differences between the sample members opinions’ averages about the study topic, due to demographic variables.E-payment methodspayment systemqualitySatisfactionpostal financial serviceAlgeria Post.Thesis
