Pump “closed” at midnight, 150 litres short by morning

It was a Friday night. The pump was officially closed and a security guard was on duty. On Saturday morning the tank measured 150 litres short. “Sir, no customer came at night,” said the guard. So where did the fuel go? The answer is unauthorized dispensing through the manual pump nozzles. An electronic nozzle lock is built to stop exactly that.

How it usually happens after hours

• The “emergency friend”: at 11 PM a staff member’s friend asks for fuel. The nozzle is worked by hand, 20 to 30 litres go out and nothing is recorded
• The duplicate key: at 2 AM a former employee who still has a pump key starts the pump and takes 100 litres or more, leaving no evidence
• The guard and an outsider: at 3 AM they sell fuel regularly and split the money

Why ordinary security fails

• The guard himself can be involved
• Keys get duplicated or lost
• Manual locks are easy to get around
• There is no record of who took fuel and when, so you cannot prove anything

What an electronic nozzle lock does

• No dispensing without the owner’s approval on a mobile phone
• Automatic lock and unlock at set hours
• Remote unlock from the phone in an emergency
• Every use logged: who, when and how much
• An SMS the moment someone tries to bypass the lock

An emergency customer at 2 AM

• The customer calls the owner
• The owner confirms who the customer is
• The owner unlocks the nozzle from the mobile app
• The staff member serves the customer
• The nozzle locks again automatically after the transaction
• The full transaction is logged

So you can still serve an emergency, with full security and a complete record.

What it is made of

• Electromagnetic lock for physical control of the nozzle
• RFID reader to recognise authorised cards or tags, with optional fingerprint verification
• Mobile app control, time schedules, different access levels for users and a complete activity log
