The background of this research is that the Nur Hidayah Mosque is one of the mosques that uses the infaq and shadaqoh transaction model through the qris code in payment. With the qris code transaction model, it is easier for people to pay infaq and shadaqoh via their respective cellphones or smartphones that have merchants such as shopee, ovo, grab, gojek and others. Most people have cellphones or smartphones that use these merchants. But the community's behavior in paying infaq and shadaqoh in qris code is less than directly. This is because most of those who pay infaq and shodaqah are clonials where they prefer to pay directly compared to qris code. One of the main keys of community behavior is lack of socialization to the community. And with this socialization makes people have knowledge. In general, people only know how to pay infaq and shadaqoh through conventional means or directly. Therefore this lack of knowledge results in the acceptance process being very minimal compared to paying conventionally. The data collection method used in this study is by using a questionnaire with a Likert scale. The data used in this study is using primary data. The population of this study is people who pay infaq and shadaqoh directly. The sample in this study was 55 respondents.
