Indian app firms cash in on Modi's rupee note switch

Indians are slowly adjusting to life after Prime Minister Narendra Modi's surprise decision to ban almost 90% of the bank notes in circulation.

The government is trying to crack down on money that is unaccounted for, but the move has sent shockwaves through India's largely cash economy.

However, some enterprising Indians are seeing opportunity amid the cash crunch.
