Consumers applying for a current or savings account or a credit card with a major bank will be able to clear identification checks by uploading personal documents from their mobile phone, tablet or computer, instead of needing to go into a branch.
Lloyds Banking Group said its roll-out of the service from next week will enable hundreds of thousands of people to open accounts more conveniently.
At present, around one in three consumers who apply online for a credit card or an account with the banking group, which includes Lloyds Bank as well as Halifax and Bank of Scotland, end up also needing to physically take documents into a branch so that they can fully pass background checks.
Lloyds said the new service will give applicants the option to upload documents they have taken copies of, such as a passport or a driving licence, rather than having to take these documents into a branch.
Those uploading the documents as part of their application will be told immediately whether or not the copies were suitable. The roll-out of the new electronic ID checks will start from next week, with people looking to add someone else to an existing account.
