This study aims to analyze the influence of religiosity, trust, transaction convenience, digital literacy, and transparency on the loyalty of zakat, infaq, and shadaqah (ZIS) donors through QRIS digital payment at Darussalam Mosque, Kota Wisata. This study employed a descriptive-verificative quantitative approach to analyze the influence of religiosity, trust, transaction convenience, digital literacy, and transparency on ZIS donor loyalty through QRIS digital payment. Primary data were collected through questionnaires distributed to active congregants of Darussalam Mosque, Kota Wisata, who had used QRIS for zakat, infaq, and shadaqah payments. The study involved 131 respondents selected using purposive sampling technique. Data were analyzed using Structural Equation Modeling-Partial Least Squares (SEM-PLS). The results showed that transaction convenience, digital literacy, and transparency influenced the loyalty of ZIS donors through QRIS digital payment at Darussalam Mosque, Kota Wisata. Transparency was identified as the variable with the strongest influence on donor loyalty. Meanwhile, religiosity and trust did not influence loyalty toward QRIS usage. These findings indicate that digital donor loyalty is more strongly influenced by ease of service use, the ability to utilize digital technology, and transparency in ZIS fund management. The digitalization of payments through QRIS also has considerable potential to increase the collection of zakat, infaq, and shadaqah not only in mosques but also in other Islamic philanthropic institutions.
