A demonstration explains how LPG ATMs function, offering an automated solution for cylinder refills. The system operates with 10 kg cylinders, unlike the standard 14.2 kg household cylinders. Users enter a cabin similar to a bank ATM booth and dial their registered mobile number on the machine's interface. An OTP is sent to the registered number for verification. After entering the OTP, an upper compartment opens where the user places their empty 10 kg cylinder. The machine accepts online payments through multiple modes including card payments and UPI. Once payment is completed, a refilled cylinder is dispensed from the lower compartment. The LPG ATM provides a self-service, automated refill facility with digital payment integration, aiming to streamline the cylinder distribution process.
