Parents in Wolverhampton face having to apply for a "passport" to take their child out of school to attend appointments such as the dentist.
Under measures being considered by the authority to tackle truancy, pupils stopped without the pass will face disciplinary action.
Education chiefs in Wolverhampton believe the scheme will be an effective weapon in the fight against truancy, one of the biggest causes of educational under-achievement.
More than 3,300 pupils were classed as unauthorised absence from Wolverhampton secondary schools last year, out of a total of 15,066 youngsters, for an average of eight days each.
At primary level 3,159 out of 19,371 bunked off without permission for an average of five days at some point.
Education welfare officers in the city have examined a pupil passport scheme operated in Leicester with a view of introducing something similar in locally.
Peter Bibb, senior education welfare officer with the authority, said: "This is a strategy we are looking at.
"We have been in touch with education and business partners in Wolverhampton.
"It is at a very tentative stage but if there are good practices elsewhere already identified then why not adopt it?"
The authority envisages getting local retailers near schools involved.
They would be asked not to serve youngsters during school hours without a pass and pupils could also be asked by police officers to show their passports.
The cards are likely to have the name and logo of the school and the city authority printed on them plus a unique number to avoid forgeries.
Mr Bibb said: "If a pupil needed to be out of school for a valid reason they would go to the school reception and say 'I have a dentist's appointment on such date' and a signature is taken before they are given the pass."
Another strategy being looked at by the authority is the creation of a "truancy free" zone, in the city centre.
It will see operations such as truancy sweeps focused on the area permanently.
The Government spends about £800 million a year on initiatives to stop youngsters bunking off school.
