I'm currently transferring to a new role which includes managing a vending machine. In the UK we adopted a new £1 coin a few years ago but no one ever updated our vending machine to accept them.
The vending machine machine has a Cashflow 690 coin mechanism made by Mars and I have checked the operating manual but couldn't find a solution. I checked their website for guidance and [http://www.marsdrinks.co.uk/resources/document-library/brochures/upgrading-to-the-new-pound-coin/|found instructions to disable old £1 coins,] but no advice for getting the new coins to work. When I tried inserting the new £1 coin no information appeared on the display so I guess its not recognised.
Are there any vending machine experts out there who know a solution to program in the new £1 coin's information using the buttons on the coin mechanism?
