The United Kingdom government has revealed more details on the technology required to underpin its controversial identity cards project.

In a "prior information notice" for interested suppliers published this week, the Home Office outlined the systems and services it will want to procure if the ID card legislation makes it through parliament.

Elements of the system which the government is looking to suppliers to provide include the creation, hosting and maintenance of a National Identity Register.

The Home Office said the hosting is likely to require "significant data centre capability" -- which will mean either building extra data centres for the purpose or using already existing resources.

Other technologies required will include the controversial biometric recording and matching technology, and services to manage the process of registering individuals onto the database.

Addition requirements include network and communications systems and support; technical integration services; secure production and distribution of ID cards and documents; and provision of office space for enrolment and administration.

The government said contact centre support services will also be needed, along with services to support the "provision of identity verification services to user organisations".

The Home Office said once the relevant legislation -- now before parliament -- has received Royal Assent, it will start the procurement exercise.

It added that in line with the "emerging delivery model" for ID cards, potential procurements may also include the current business activities of the United Kingdom Passport Service and build upon existing systems and processes.
