CSB One Co-Branded Credit Card

CSB Bank · Applications paused

A lifetime-free Mastercard credit card from CSB Bank and OneCard, run entirely from the OneCard app. It earns 1 reward point per ₹50 and 5X points on the holder's top two spend categories each month, with a 1% forex markup. A point is worth about ₹0.10 against the bill (OneCard's own explainer), so the base rate is 0.2%. New applications are probably paused.

Terms the calculator does not value

  • 5X rewards: the top 2 spend categories of a calendar month earn 5 times the points if the month has purchases in at least 3 categories with at least ₹750 in each (from 2025-01-06). Categories follow MCCs and the bank may reclassify merchants. Which categories are "top" depends on the holder's own month. For education, bills and insurance the 5X increment is limited so that total rewards in those categories stay under 25,000 points. 5X points are credited on the 10th of the next month.
  • The ₹0.10 point value comes from OneCard's 2021 rewards explainer (500 points = ₹50 off the bill). No CSB document states a value, and the T&C let the bank change the conversion rate at its discretion.
  • Referral programme and merchant EMIs: merchant EMIs earn no points; the T&C pay referral bonus points (2,500 per activated referral) that do not count for 5X.
