JAM (Just a Minute) cards

The Just A Minute (JAM) card can be used by people with learning disabilities, autism, or a communication barrier to tell others that they need a 'minute' in a discreet and easy way when they are in environments, such as supermarkets or public transport.

JAM cards are available as an app, or a physical card. You can apply online for free or pick one up from your local library: https://www.jamcard.org/
