Rather, it is using "sophisticated Currency Verification and Processing (CVPS) machines for checking the numerical accuracy and genuiness of the currency notes, including SBNs (Specified Bank Notes that have been scrapped)", the RBI clarified later this evening.
"These machines are way superior to the note counting machines. With a view to augmenting processing capacity, the RBI is using the available machines in two shifts and has been using some machines temporarily drawn from commercial banks after suitable modifications. The RBI is also exploring other options to augment processing capacity even further," the central bank said in a statement.
An official also clarified that the counting machines are typically very small and are mostly used in branches of commercial banks for smaller number of notes.
In reply to the RTI application, the central bank had also refused to give the total number of personnel deployed for counting of the scrapped notes, saying compiling the information would "disproportionately divert" its resources.

In its annual report for 2016-17 released on August 30, the RBI had said Rs 15.28 lakh crore, or 99 per cent of the demonetised Rs 500 and Rs 1,000 notes, have returned to the banking system.
As on November 8, 2016, when the note ban was announced by Prime Minister Narendra Modi, there were 1,716.5 crore pieces of Rs 500 and 685.8 crore pieces of Rs 1,000 notes in circulation, totalling Rs 15.44 lakh crore, it had said.
"Counting machines are not being used for the purpose in any offices of Reserve Bank of India," the RBI said in the RTI reply dated August 10.
It was asked to give details about machines being used for counting the Rs 500 and Rs 1,000 notes.
The central bank also denied sharing information on the total number of personnel deployed for counting of the old notes.
"Compiling the information would disproportionately divert the resources, the information sought cannot be furnished as per Section 7 (9) of RTI Act, 2005," the RBI said in its reply to the RTI query filed by a PTI correspondent.
The Section says information shall ordinarily be provided in the form in which it is sought unless it would disproportionately divert the resources of the public authority or would be detrimental to the safety or preservation of the record in question.
The RBI did not give any specific reply when asked about the last date of counting of the demonetised notes.
"Subject to future corrections based on verification process when completed, the estimated value of specified bank notes received as on June 30, 2017, is Rs 15.28 trillion," the central bank had said in its annual report.
While the counterfeit currency notes made up for a minuscule number, the RBI post-demonetisation spent Rs 7,965 crore on printing new Rs 500 and Rs 2,000 and other denomination notes, more than double the Rs 3,421 crore spent in the previous year, it said.
In his reaction to the RBI report, ex-finance minister P Chidambaram had wondered whether demonetisation was "a scheme designed to convert black money into white".
"RBI 'gained' Rs 16,000 crore, but 'lost' Rs 21,000 crore in printing new notes! The economists deserve Nobel Prize.
