Nimbus Disability is a social enterprise and an organisation run by and for disabled people and is recognised as a lead authority on accessible ticketing in the UK.

Nimbus developed The Access Card in response to frustrations shared by disabled people and a major live music promoter in how disability was evidenced and needs for reasonable adjustments communicated:

• For disabled people, the frustration was in repeatedly sending in personal documents which bore no direct relation to the needs of the individual.
• For the venues, it was frustration in interpreting these documents and the additional admin burden it placed on their staff.

Since its initial development, the card is now widely accepted at major event venues across the UK and beyond, and even more widely taken simply at face value.
