stop multiple crb checks with one card

I am a govenor of a secondary school and so have had a crb check.

i am told that if I want to help with other organisations like scouts youth club etc i have to have a separate crb check for each one.

!. Is this true ?

2. If it is wouldn't it be better to have (carry) a registration card the size of a credit card with photo and details of ID  renewable every year and then I could be able to volunteer for more.

I have a card for my driving licence

credit cards

Bus pass

Visa

Why not for CRB chech as well.

Why does this idea matter?

volunteering is being curtailed by having a check for every job.
