Consumers' increasing aversion towards credit cards  continues to be a feature of the monthly data on payment cards published by the Reserve Bank of Australia.Over the six months to April 2010, purchases with debit cards gained 130 basis points in the share of the value of payment card purchases from credit and charge card, Mike Ebstein, of MWE Consulting, noted in his monthly analysis of payments data. This compares with a gain in market share for debit cards in the six months to October 2010 of 70 basis points.MWE put the market share of debit cards at 38.7 per cent in April 2011, up from 36.7 per cent in April 2010 and 32.9 per cent in April 2008.A related indicator of the aversion toward credit cards is the decline in the use of cash advances. Personal credit card cash advances fell below A$10 billion over the year to April 2011, according to MWE.The average cash advance per account - at A$730 - is down by six per cent over one year and 21 per cent over three years.Growth in spending on all types of payment cards was 2.4 per cent in April 2011 compared with April 2010, or about half the rate of growth in the year ending April 2011 and below the rate of inflation.Separate data compiled by the Australian Bureau of Statistics shows that the flow of new business loans fell sharply in April 2011 from March.On a seasonally adjusted basis, the ABS put new lending at A$29.4 billion for the month - down from $32.2 billion in March. On a trend basis, new business finance fell 0.9 per cent in March.
