A special smartcard and web portal for Londoners could be in place by 2005, if plans developed by LondonConnects are successful.
The agency, which is bringing together local and national government to work on e-government developments, has unveiled its draft strategy for the capital in a new report.
Its proposals include a portal giving access to local and centrally provided public services and information, with common city-wide standards for authentication and payment.
"Unlike other major world cities, London does not have a single capital-wide portal, and establishing the London Portal will be high profile evidence of the city's commitment and ability to retain its place as the e-capital of the UK and Europe," says the report.
The portal will link to other public portals, and provide security and authentication features for different services, as well as information for visitors. The www.ukonline.gov.uk site and its underlying technology, the Government Gateway, could be used as building blocks for the London Portal.
LondonConnects hopes that delivery and support of the portal will come from the private sector, and is developing a case for some government funding.
It also wants to build on initiatives which are in progress at the moment to develop a London-wide smartcard to give access to services and facilities. The London Borough of Newham, Transport for London and Southwark Police are all working on smartcard projects already.
LondonConnects also wants to explore the idea of a London Public Services Network which would be a secure network for all public services, but which could be more cost-effective than each service building its own network. It further suggests that all new houses should be e-enabled to boost broadband penetration.
London mayor Ken Livingstone said in the foreword to the report: "There are three key areas on which, I believe, we need to focus attention if London's competitiveness is to be maintained and developed.
"We must ensure that affordable broadband access is available right across the city; we have to develop our e-skills; and through technology we must ensure our public services are accessible and easy for everyone to use."
LondonConnects wants responses to the draft strategy, which can be sent via its website at www.londonconnects.org.uk. The closing date for responses is 28 February.
