Under the new system, a unique photo card will also be needed to enter the attractions. Previous winners can apply for a card on the Blue Peter website.
The idea for the new scheme came from 11-year-old viewer Helen Jennings.
Jennings wrote in to the show with a prototype design for the security card, Blue Peter editor Richard Marson said.
“On Blue Peter many of the best ideas come directly from the audience and this was no exception,” he said.
“As a result, she’s won her silver badge and really helped all the genuine Blue Peter badge winners out there who’ve been so upset at the suspension.”
I hate this. Nobody is fooled. An 11-year-old did not invent the photocard.
