A Power of Attorney (PoA) for Demat Account is a legal document that gives limited legal authority to the Zerodha to operate your demat account. It authorizes Zerodha to debit/credit shares from your account when you buy/sell online or when you want to pledge the shares.
In online trading, a PoA is required by the broker to meet the obligation of delivering the shares in T+2 days, when the customer sells them online. PoA is mandatory by all the brokers if you are selling stocks with them online. The PoA can be revoked anytime by the customer.
