How does a crypto card work?
A crypto card connects a payment account to a card network. When a user pays, the card provider either deducts a funded balance, converts a digital asset, or uses an approved credit line. The shop receives the transaction through the normal card network and does not need to accept crypto directly.
A crypto card still depends on identity checks, regional availability, supported assets and the provider’s transaction rules. A card that works for online subscriptions may have different ATM, wallet or foreign currency conditions.
Which type of crypto card is it?
| Card type | Where spending money comes from | Main risk |
|---|---|---|
| Prepaid crypto card | A balance loaded before spending | You cannot spend more than the available balance |
| Crypto debit card | Digital assets or cash held in the connected account | Conversion cost, provider custody and asset price movement |
| Crypto rewards credit card | A traditional credit line, with rewards paid in crypto | Interest, debt and changing reward value |
| Collateral backed crypto credit | A credit line secured by pledged crypto | Interest, locked collateral and possible forced asset sales |
What type of crypto card is RedotPay?
The standard RedotPay card spends from supported assets held in a RedotPay account. RedotPay converts the required balance for a card payment. The standard card is not a traditional revolving credit card.
RedotPay also offers a separate Credit feature. RedotPay Credit can provide a spending limit backed by eligible non stablecoin assets. Users who activate Credit borrow against collateral and pay interest, so the risks differ from ordinary funded card spending. Read the independent RedotPay Credit guide before using it.
What does a crypto card cost?
Crypto card costs can include issuance, asset conversion, foreign currency, ATM, funding, replacement and merchant specific fees. RedotPay currently lists a 10 USD virtual card issuance fee, a 100 USD physical card issuance fee and no standard annual card fee. Usage fees can still apply.
The most useful comparison is the total cost of one realistic transaction. Card Atlas’s RedotPay card fee guide shows the published rates and worked examples instead of comparing only the annual fee.
What are the main crypto card risks?
- Provider custody: funds held in an app account are not the same as assets in a self custody wallet.
- Asset movement: non stablecoin assets can move sharply, and stablecoin pegs are not guaranteed.
- Fees and spreads: more than one charge can apply to the same purchase.
- Availability: citizenship, residence and local rules can block registration or a card feature.
- Credit risk: collateral backed credit can lock assets and create interest or liquidation risk.
How do you get a crypto card?
For RedotPay and Karta, getting a virtual crypto card involves an eligible account, identity verification and a separate issuance payment. Choose the funding model first: spending an existing balance and borrowing against crypto are different decisions.
- Check citizenship and residence before depositing. Use RedotPay’s restrictions and Karta’s eligibility guidance; Karta directs users to support for its full unsupported-country list.
- Prepare the identity documents requested in the provider app. RedotPay’s identity check includes an ID, face verification, address and questionnaire. Karta’s onboarding also requires identity verification.
- Check the exact asset, network and net deposit amount. RedotPay’s deposit rules require the minimum to be met after network fees. Do not choose a network only because it has the same token name.
How do you apply for a RedotPay virtual card?
- After identity verification, have enough eligible account balance for the published 10 USD issuance fee.
- In the app, open Card, select the virtual-card application and enter the billing address in English.
- Check the details and final charge before paying. RedotPay says the application payment cannot be canceled or refunded.
See RedotPay’s official virtual-card steps. The 5 USDs welcome reward cannot pay the issuance fee.

How do you apply for a Karta virtual card?
- Open Karta, complete its questionnaire, identity-document check and liveness check, then wait for approval.
- Once approved, select Visa Virtual and review the published 5 USDT issuance charge before confirming.
- Karta says activation usually takes up to an hour after purchase. That is an estimate; contact Karta support if activation takes longer.
See Karta’s official getting-started guide. Check eligibility and current app terms before funding.

Is the issuance fee money you can spend?
RedotPay says its issuance fee is not spendable balance. For example, 30 USD of eligible balance minus the standard 10 USD virtual issuance fee leaves 20 USD before other charges. This is arithmetic, not a minimum-deposit recommendation or a guarantee of a 20 USD purchase: conversion and transaction fees may still apply.
