 First Minister Jack McConnell launched the scheme |
Pensioners and people registered disabled will be able to travel free on all Scotland's buses from Saturday. The new national scheme replaces local off peak arrangements which have been running for the past four years.
The Scottish Executive is allocating �159m for the first year, so that anyone over the age of 60 and people with reduced mobility can travel free.
It said uptake had been good with most local card scheme holders applying for the new national entitlement card.
The executive has also promised that 97% of people who have applied will receive their cards in time.
Others will be still able to use their old cards for local travel if they have not received their national card.
Launching the scheme at Buchanan Bus Station in Glasgow, First Minister Jack McConnell said: "These pensioners are saying to me it will make them healthier, fitter individuals.
"They are saying that what we spend on this scheme we are likely to save in health and care costs - because Scottish pensioners will be in such better shape."
The Welsh Assembly introduced a similar scheme in 2002 and said it had been "highly successful".
