The RNID is launching its own affinity credit card in association with the Bank of Scotland.
Every time someone first uses the card, the RNID will receive £5, with another £5 going to the charity if the card is still being used after 12 months. For each purchase worth £100, the RNID will get 25p.
Halifax and Bank of Scotland (HBOS) Card Services staff will receive deaf-awareness training as part of the deal.
The card's design features seven people, one picked out in colour, to focus on the charity's key message that one in seven people in the UK are affected by deafness.
The RNID wanted to link with HBOS because it had committed to good customer service for the hard of hearing. HBOS affinity cards raised £4m last year.
