You may be wondering now what is TPIN ? TPIN means a 6-digit unique code that allows your stockbroker to debit shares from your Demat account. CDSL stores every user’s TPIN in its database. This facility came into existence on June 1, 2020. It is one of the best ways to secure all your Demat account transactions.

The stockbroker would ask you to provide your e-sign on a Power of Attorney (PoA) while opening a Demat account online. 

PoA is a legal document by which you permit the stockbroker to decide and act on your behalf. For example, your stockbroker will get the limited authority to debit a financial asset from your Demat account when you place a sell order for it. 

Many activities take place without the concern of customers in terms of PoA. 

Here are some disadvantages of PoA— 

  • Securities withdrawal occurs when a customer doesn’t place an order to sell. 
  • Securities transfer from a Demat account to a broker pool account. 
  • To make customers fearful and pay to avoid trading losses.

CDSL Full-Form

CDSL stands for Central Depository Service Limited, responsible for generating and managing the Transaction Personal Identification number.
