What are the names of the payment gateway vendors in Zerodha?

Zerodha uses NTT DATA payment services (ATOM) and Pine labs payment gateway (Billdesk) as its payment gateway vendors. When funds are transferred to Zerodha accounts through net banking, clients are redirected to them.

However, if funds are transferred through an IDFC 3-in-1 account, ICICI, SBI, HDFC, Kotak or Axis bank, clients will not be redirected to NTT or Pine labs as Zerodha has a direct payment gateway with these banks.
