Addressing a public rally in Ujjire near Dharmasthala, a temple town in Dakshina Kannada, PM Modi also took a dig at the opposition for its criticism of demonetisation aimed at making the economy less dependent on cash, saying even parents limit cash given to their children because it spoils them.
Without naming Rajiv Gandhi, PM Modi recalled that a former Prime Minister had said that from every rupee sanctioned by the government, only 15 paise reached its beneficiary in a village.
"One of the Prime Ministers had said every rupee is reduced to 15 paise when it reaches a village after getting sanctioned from Delhi. Which hand reduces the rupee?" he asked, in a sarcastic reference to the Congress election symbol.
He said this was not the case with his government that was committed to devote every rupee and every resource for the welfare of Indians so that fruits of development reached the beneficiaries without any scope of corruption.
PM Modi said cash currency had always been changing from stone coins, rubber coins, gold and silver coins in the economic history of the world and now it was the time for digital currency in the world. "India cannot lag behind."
PM Modi launched the distribution of RuPay Cards for Self-Help Group members and gave the cashless cards to two women enrolled for Pradhan Mantri Jan Dhan Yojana.
He said such self-help groups, who have pledged to conduct their businesses cashlessly, have answered all those who spoke against demonetisation, questioning how was it possible to become cashless in a country where the poor and less literate have no digital connectivity.
"Even parents limit cash to their children because they think it will spoil them. That is why self-accountability is very important."
He urged people to use Bhim App and embrace cashless transactions in the "era of honesty and integrity" where there "is no place for those who cheat the system".
Earlier, PM Modi arrived in Karnataka to take part in various public functions. He landed at the Mangaluru airport and flew to Dharmasthala in a helicopter.
He prayed at the Manjunatheshwara temple in Dharmasthala, about 100 km away from Mangaluru. Due to PM Modi's visit, the temple administration restricted public entry till 2 p.m. on Sunday.
Later, PM Modi is expected to fly to Bengaluru to attend a public function organised by the Vedanta Bharati at the Palace Grounds.
In the evening, he will inaugurate the 110 km Bidar-Kalaburgi railway track in the Hyderabad-Karnataka region that would reduce the distance between Bengaluru and New Delhi by 380 km and travel time by six to eight hours.
