If it is not halal what can be the other way for me to work for this so that my money should be Halal.
Answer:
(Fatwa: 1048/594/D=1432)
When the said software may be used for general purpose, then it is lawful to sell it to the banks. The income shall be halal, provided unlawful matters have not been included in that software.
