I recently tried paying my credit card bill via hdfc debit card via their app , to avail the 1% cashback
And to my surprise the bill automatically appeared there within seconds, So I'm curious to know how this works , who do they collect and ask data from so quickly and know the bill amount to pay.
Does anyone know how this is done?
