The Home Secretary will be spreading the message on identity cards among schoolchildren today.
Jacqui Smith is meeting students before attending a police presentation on combating gang-related crime in Manchester.
She is visiting Newall Green High School in Wythenshawe, a deprived part of the city.
The school is a specialist arts, science with mathematics and vocational college, with around 900 pupils.
Two years ago the school inspectorate Ofsted judged Newall Green to be “outstanding”.
A Home Office spokesman said Ms Smith is expected to “discuss with students how identity cards will help them strike out on their own.”
She will also give a speech about identity cards to business and community leaders at Manchester Town Hall.
The Home Secretary is meeting with Greater Manchester Police (GMP) officers to learn about Operation Cougar.
A GMP spokesman described Cougar as “a ground-breaking operation that has had a significant effect on gun and gang crime in Greater Manchester”.
