Plans to abolish the use of cheques as a payment method are to be investigated by a parliamentary committee.
Cheques are set to disappear by the end of the decade, with the UK Payments Council planning to phase them out by October 2018.
In December it announced it would push consumers towards using alternative payment methods to prevent them being left "high and dry".
MPs on the Treasury Select Committee plan to determine the impact removing cheques would have on certain society groups, such as pensioners and small businesses.
It will also look into the pros and cons of the payment method, which has been steadily losing popularity since 1990. Supermarkets, petrol stations and high street shops have mostly stopped accepting cheques as they cost about a pound to process.
Cheque usage has dropped 40% in the past five years, and could drop to just 1.6 million a day by 2018 if trends continue. In 2008 there were 3.8 million cheques paid each day.
