Richer and poorer households disagree over Christmas contactless spending limits.

Nearly half (48%) of shoppers would like to customise their contactless card transaction limit, or would like to the ability to do so, according to new research* from Paymentsense. For those shoppers wanting a customisable limit, just over a quarter (26%) would immediately raise it, but nearly 1 in 5 people (18%) would lower it. The top reason for those wanting to raise the limit is that £30 is too low (44%).For shoppers keen to lower the limit (20% of those surveyed), the main reason was concern over fraud or theft (53%). A further 23% of shoppers want to lower the limit to help manage fluctuating finances.When it comes to Christmas shopping, the study also revealed divisions between higher and lower income households. On average, over a third (38%) of those on a lower income (up to £30,000) would not raise the £30 limit over Christmas, fearing overspending on presents and food and drink.
