If you thought India's decision to ban 86% of its cash was ambitious, wait until you hear what it may do next.
Amitabh Kant, the head of a government-run policy institute, said that the country could completely eliminate the need for credit cards, debit cards and ATMs in the next three years by switching to biometric payments.
Kant said that even electronic payment methods may be "totally redundant" by 2020.
Instead, all Indians need for transactions is their thumb or eye.
Arundhati Bhattacharya, head of the State Bank of India, agreed that such a dramatic shift was possible.
"This is something that's eminently doable," she said, pointing out that nearly 1.1 billion of India's 1.3 billion people have already registered their biometric data under the government's unique identification program.
The Indian government is testing a payments app that makes use of biometric data, coupled with portable fingerprint scanners that cost about 2,000 rupees each.
Eliminating credit cards will likely be even tougher, but India appears determined to try.
