The facility has been made available at 19 places in Parliament, including canteens for MPs and media as well as in the Central Hall.
Parliament's Food Committee Chairman A P Jithender Reddy, who played a key role in implementing the cashless system, told PTI that the step was taken to make it easy for those making payments.
He said in the wake of cash crunch, people have been finding it difficult to make payments in Parliament canteens. "Sometimes, there was no cash to pay or sometimes there was no change available with the canteen cashier. Card payment will address that situation," said Reddy, a Lok Sabha member of Telangana Rashtra Samithi (TRS).
Asked about the reaction, Reddy said everybody in Parliament, including MPs, is happy over the move.
After demonetisation on November 8, Prime Minister Narendra Modi has been vigorously campaigning for shift to a cashless society across the country.
