Each ATM machine has only 3-4 cassettes that can hold cash in it to dispense. Each cassette has to be configured to dispense a particular value. So far, all ATMs were configured for Rs 100, Rs 500 and Rs 1,000 denomination notes. Official of a company (not FSS) that also manages the ATMs said: “Every ATM has ‘cassettes’ which can hold a particular denomination. To be able to provide Rs 2,000 denomination notes, the cassettes have to be configured, which will take time.” His company is trying to configure one cassette for Rs 50 notes, the software for which is available with it unlike the Rs 2,000 cassettes to be designed and then configures.
