Young people involved in anti-social behaviour could have their free bus passes suspended in a move being considered by the Scottish Government.
It follows concerns rising among MSPs that the scheme is being abused, with Aberdeenshire West MSP Alexander Burnett saying youngsters are "causing carnage in areas they previously could not access".
Transport Minister Fiona Hyslop told MSPs she has asked about what "digital blocking measures" could be used.
She added: "I understand this would require police time and cooperation, and identification of offending individuals, increased administrative time and expertise, and technological fixes which are not yet apparent.
"I want to be clear this would not be age specific."
Tory MSP Burnett told Holyrood of an incident at Deeside Rugby Club in which a group of teenagers who travelled from Aberdeen "barged into the club house, threw insults at members … and were clearly only intent on a trouble-making spree".
He added: "Due to social media trends, we are seeing an increase in this behaviour – a minority of young people travelling simply to cause carnage in areas they previously could not access."
Scottish Conservative Transport Spokesperson Graham Simpson welcomed Hyslop's move, saying: "There is also a perception that the scheme may have also contributed to increased anti-social behaviour in and around bus stations and other locations such as shopping centres."
He added: "If the culprits hold a free travel card, then they are abusing a privilege paid for by the taxpayer and that should not continue."
