In its biggest crackdown ever on black money, the government on Tuesday night announced demonetisation of Rs 500 and Rs 1,000 notes and asked people holding such notes to deposit them in bank accounts.
Since Thursday people have been thronging banks amid concerns among people over exchanging and depositing the scrapped high denomination currency.
People can deposit old Rs 500 and Rs 1,000 notes in their accounts till December 30, 2016, without any limit.
Restrictions have been imposed on the withdrawal limit and people can withdraw up to Rs 10,000 per day or Rs 20,000 per week.
This limit will be reviewed after a few days.
Besides, old notes up to Rs 4,000 can be exchanged at any bank or post office till November 24, 2016, by showing photo ID as proof.
ATMs can be used to withdraw up to Rs 2,000 per day per card till November 18 and Rs 4,000 from November 19 onwards. This limit too will be reviewed subsequently.
The ministry also advised people to make payments using cheques, demand drafts, debit or credit cards and electronic fund transfers and there is no restriction on such transactions.
