Trying to choose between the KAST Card and the RedotPay Card? We’ve reviewed and tested both, so let’s put them side by side.
Both are USD-denominated Visa cards, but the KAST is a credit card while the RedotPay is a debit card. The real differences are in the fees, the cashback, and what you can do with your money — so that’s what we’ll focus on.

Which Card Has Lower Fees?
When you pay with the KAST Card, converting your crypto into USD costs you 0%. The RedotPay Card charges ~1.5% for the same conversion.
That makes the KAST the cheaper card to actually spend with — and the difference adds up if you run a few thousand USD a month through it.
Neither card charges a monthly fee. You only pay when you spend.
Here’s exactly where each card’s conversion cost comes from:
What About Foreign Exchange Fees?
Pay in a currency other than USD and the KAST Card adds a 1.75% foreign exchange fee. The RedotPay Card adds 1.2%.
If you travel a lot, or just live outside the USD zone, the RedotPay is the kinder card to your wallet here.
Stack that on top of the conversion cost, and a non-USD purchase costs you about ~1.75% in total with the KAST, versus ~2.7% with the RedotPay.
How Much Does Each Card Cost to Get?
The KAST virtual card is free, and the physical card costs $40. The RedotPay virtual card is $10, with the physical at $100.
If you just want to try one of them out, the KAST is the cheaper way in — the virtual card costs you nothing.
One more detail: the KAST card is valid for 5 years, the RedotPay for 3 years.
Which Card Pays Better Cashback?
The KAST Card pays up to 5%, and the RedotPay Card pays up to 3%.
On the free tiers, the KAST starts at 1.5% (capped at $30/month) — the top rates need a paid or staked tier.

If ATM access matters to you, the RedotPay gives you a lot more headroom.
