Expressing satisfaction that digitisation is expanding at a much faster space than anticipated, Jaitley said transformation of post offices into a bank will be the next revolution.
In an apparent reference to criticism of demonetisation by opposition parties, Jaitley also said there would have been complaints even before cash or currency was invented and even if it gets eliminated tomorrow.
"In the context of demonetisation, the obvious attempt was that the extent of the paper currency must be replaced by digitised economy...This expansion is going to take place much faster than any commentators anticipated and the reasons are very obvious," he said after launching Airtel Payments Bank here.
He also noted that the new generation in India take to emerging technologies and techniques quite easily.

Expressing hope that entry of more telecom players in the banking space will help push financial inclusion, he said entry of post offices would add a new dimension.

When volumes are going to increase, service charges are going to be minimal because the fixed cost remains the same, he said.
With JAM (Jan-Dhan, Aadhaar and Mobile) and increased digitisation, banking costs are going to be minimal in the country, he added.
Taking a dig at critics of digital economy, Jaitley said this will provide adequate response to ill-informed criticism that digital space would only be occupied by credit card revolution.
