There are three token counters near taxi stand at Badrinath. You can collect your token (free) from one of these counters.
Token mentions darshan time and you need to be at the main door 10 – 15 minutes in advance. Please note that time allotted for darshan of the Lord Badrinath is only for 10 – 20 seconds in the peak season of May to July.
The token system was started in 2012 as a 10 day trial, but with its great success it has been continued for the Char Dham 2012 season.
With the token system there is no need for pilgrims to stand in long queues for several hours outside the temple, and pilgrims now visit other nearby spots in the time which was otherwise going waste.
