The Institute of Fundraising has opened a consultation on its revamped code of practice on the handling of cash donations, which includes sections on card and electronic transactions for the first time.
The institute said there had been a diversification of income sources for charities.
The code contains sections on cheque donations, the use of debit cards, tax-effective giving and electronic transactions and guidance when using tills.
The name of the code has been changed to Handling of Cash and Other Financial Donations to highlight the changes.
Sarah Tirrell, policy and codes practice manager at the IoF, said the draft code reflected the importance of donation methods such as cheques.
"Its update means that our guidance keeps in step with other practicalities of contemporary fundraising, including technological advances that have affected our sector in the past few years," she said.
The public consultation process starts today and will close on 3 May.
