Punbus / Punjab Roadways — E aadhar / Mobile aadhar no accepted

Team,

Today i was travelling from jalandhar to hoshiarpur and back along with my mother. My mother presented her aadhar on mobile to conducter and even downloaded it in front of him.but he still denied to accept the same and my mother got charged both time.

I don't understand reason for not accepting e aadhar when only aadhar no is to input in pos machines

Please resolve.
