London charity the St-Martin-in-the-Fields Trust, which supports the work of the Trafalgar Square church in helping women move away from homelessness, is to benefit from a rounding-up option that allows debit card holders to automatically donate small sums when they spend.
Users of the card in question - Currensea - can opt to round-up UK spending, in-store or online, to the nearest 5p and donate this to the Trust.
