I am not a ghost customer yet, but planning to use it in the future. I would really like to have UPI payments system on ghost. UPI is a very popular payments system in India. It is so popular that people use it more than they use cards and NetBanking. UPI allows subscriptions as well as one time payments. It would be great if ghost can integrate UPI payments. By staying out of the UPI system, a large market is left out of equation. I hope ghost takes a note of this.
