Ticket checks will be beefed up at Edgar Street to catch dishonest fans trying to get away with cheaper tickets.Hereford chair Chris Ammonds, left
Extra checks will be rolled out because Hereford have learned some supporters may be using Under 16 match or season tickets to watch games, when in fact they should be buying adult tickets.
Despite only a "small minority" thought to be doing this, the club warns it could be costing the club "a significant amount of money".
In an article on the official website, the club warned that over the course of a season, that money could be used - including being added to the playing budget to strengthen the squad.
Bulls chairman Chris Ammonds said it was disappointing to hear and the club would be taking action.
Turnstile operators won't be asking fans for ID as they are volunteers and there are sizeable crowds at the moment.
Instead, stewards will be stopping fans to check they have a valid match or season ticket and anyone found not to have one will not be allowed entry to the ground.
Fans are being urged to allow more time to get into Edgar Street for that reason.
He also said ticket system information is being checked to find 'unusual patterns'.
