Continuing the discussion from Does jupiter bank has cheque book!:
Today, I tried ordering the Cheque Book, even mailed my signature and Pan Card (less than 100kb in size). But, support team informed me that cheque book service is not currently available as they are facing a technical disruption, further I was informed that they don’t know when is it going to be resumed and engineers are working on it.
So, as of now no cheque facility 
, I hope Jupiter team works on it and bring it back online.
