As more and more of the new currency comes into circulation and re-circulated in the banking system, ATMs will make it increasingly available, Jaitley said.
On the advantages of the demonetisation move, he said a large volume of cash has come into the banking system and taxes will be recovered wherever they are not paid.
"Future transactions would be substantially digital and once they are substantially digital they get caught in the tax net. Therefore the future taxation level would be much higher than what is currently being collected," he said.
It would also enable the government at some stage to make taxes more reasonable which will apply to both direct and indirect taxes, he said.
Also, the banking system will have lot more cash, which will boost it's ability to support economy with low cost lending.
"Obviously with all these advantages the social cost also on the system will go down. Therefore, the cash used for bribery, for counterfeit currency, for terrorism, for evading taxes itself will go down," he said.
Taken together with other reforms particularly the proposed GST and the restrictions on cash spending subjected to PAN declaration, it is going to "bring down the levels of corruption in society", he said.
"It is going to bring down cash transaction in society and it's going to bring down levels of evasion as far as taxation is concerned," he said.
Stating that the government is ready for a debate on the demonetisation issue in Parliament, he urged the Congress and other opposition parties to "rise above slogans and look at the positive advantages that this changes system in the long run is going to bring to the economy as a whole".
"Therefore, from national perspective, I would appeal to the opposition to join this campaign rather than create obstruction and fail to understand what the real purpose and the import of this campaign really is," he said.
