KAST Points are a loyalty layer paid on top of USD cashback for paid tiers. KAST has not published a fixed conversion rate for them, so their value is variable.
Kast Card Fees and Limits
Kast Card fees and reward conditions to know before you sign up:
- Standard tier has no annual fee, while paid tiers carry a significant yearly cost
- FX fees apply on spend in non USD currencies
- ATM withdrawals carry a flat fee plus a percentage, plus operator charges
- An inactivity fee applies after 12 months without use
- Rewards are locked for 14 days before you can redeem them
- Cashback is reversed if a purchase is refunded or charged back
- ATM withdrawals, fees, and conversions earn no cashback

Is the Kast Card Referral Code Worth Using?
The Kast Card referral code 6MHGEMGE costs nothing, and there is no version of signing up where leaving the field blank helps you. Use it.
Whether the card suits you is a separate question. Standard is free, so the downside of testing it is small. Paid tiers only make sense at high monthly spend, since you pay the annual fee up front against cashback you may not earn back.
