The spending limit on contactless payments has been increased to £30. The new limit, up from £20, means the average supermarket spend of £25 will now be covered by the increasingly popular payment method.
Most card terminals should already be able to process the higher transaction, but some might not be updated for "a number of weeks", according to industry trade body The UK Cards Association (UKCA).
More than £2.5bn has already been spent on contactless cards in the UK this year, compared to £2.32bn for the whole of 2015. The increase in the contactless payment limit was introduced in response to the popularity of the technology.
"The growth in contactless payments shows people want to use contactless cards and increasing the limit gives customers even more opportunities to pay in this way," said Graham Peacop, chief executive of UKCA.
There are already more than 69 million contactless payment cards in circulation in the UK, with more than 9.3 million of those issued between January and June 2015.
The increase to £30 was first announced in February and since then the popularity of contactless has continued to rise with the launch of Apple Pay and Barclay's bPay service giving further options to pay without chip-and-pin.
Despite increased use fraud on contactless cards was still "extremely low" at one penny for every £100, according to UKCA.
