The tendency of the community towards halal products is currently increasing, not only
related to objects/goods but also related to muamalah/interactions. The development of the latest fintech
applications needs to be examined and detailed again, to be linked with related sharia law. In addition to
examining legal status, an interesting thing to develop is how to formulate a fintech application that is
following the Islamic economic perspective. Therefore, it is crucial to always review the National Sharia
Board – Indonesian Council of Ulama (Dewan Syariah Nasional – Majelis Ulama Indonesia – DSN-MUI)’s
fatwa related to fintech applications in Islamic financial institutions (LKS). The results of this study will be
used as input for DSN-MUI to formulate policies and fatwas that is issued. This research is a qualitative
type. The research subjects are; (1) Sharia Cards, (2) Sharia Charge Cards, (3) Transfers and Collections,
(4) Payment Services, and (5) Sharia Electronic Money. There are differences in the bases for
determining the contract of each of these products between Islamic countries. The results of this study
indicate that: (1) the sharia card product is more appropriate to use the hawalah contract than the kafalah
contract, and it is necessary to fix fines due to maturity, monthly fees that are not related to the amount
of debt, and to write off merchant fees; (2) Sharia Charge Card products should use a hawalah contract
rather than a kafalah contract and need to eliminate fines due to late payment; (3) the use of the wakalah
contract on transfer and collection products is correct; (4) payment service products that use a wakalah
and ijarah contract should be sufficient to use one of the two; and (5) electronic money can function as
money, with transactions using the hawalah principle, as well as debit cards (wadi'ah principles). So, four
improvements are proposed to the DSN-MUI fatwas related to the fintech application.
