Check residence, documents and applicant type separately
Holding an accepted document does not establish eligibility in every country. Residence, document-issuing country, card-issuing region and individual or business status can have separate conditions. Find the rules for the exact product and region.
| Your documents | Find an explicit statement about | Also confirm |
|---|---|---|
| National ID | Accepted document types and issuing countries. | Supported residence and any additional evidence. |
| Passport | Passport type, issuing country and validity requirements. | Whether the residence conditions are also met. |
| Passport and proof of address | Accepted evidence, issue dates, names and addresses. | Whether the documents establish your actual residence. |
| Business documents / KYB | Supported incorporation locations, company evidence and verification steps. | Director, beneficial-owner or authorized-person documentation. |
Classify each result as explicitly eligible, explicitly ineligible or not stated. The absence of a published prohibition is not approval; clarify uncertain conditions before transferring funds.
Five steps from eligibility to usable payments
- Remove ineligible products first. Record the official conditions for the actual region and card range.
- Choose the main use case. Advertising, subscriptions and shopping have different priorities.
- Compare the same operating assumptions. Use the same funding total, deposit count, billing currencies, purchase count and period.
- Check operational constraints. Include funding networks, minimum deposits, payment limits, 3DS, refunds and account-exit rules.
- Test a small amount through the workflow. Verify application, funding, payment and reconciliation before adding working payment funds.
Choose by use case rather than a headline reward rate
| Use case | Priorities | Next step |
|---|---|---|
| Advertising | Merchant support, multiple cards, team permissions, budgets, limits, 3DS and unsuccessful-payment fees. | Advertising payment guide |
| AI and software subscriptions | Merchant compatibility, recurring charges, small-payment fixed fees, issuance and monthly fees. | Understand the cost categories |
| Cross-border shopping | Settlement currency, FX charges, 3DS and refunds; check physical-card and ATM terms if needed. | Application checklist |
After identifying a few candidates, consult our existing card comparison and the provider's latest terms. This guide does not duplicate the full product comparison table.
Estimate how much of the budget can reach merchants
Bring issuance, percentage funding charges, fixed deposit fees, fixed authorization fees, conversion and FX into the same budget. The estimator follows the reference article's comparison method and adds funding frequency and separately paid network costs.
Adjustable cost estimator
Illustrative defaults only. Enter the current terms for the actual card; this is not a provider quote.
- Estimated merchant spending
- Comparable loss (excl. network)
- Total cost (incl. network)
- Loss on total outlay
- Percentage funding fees
- Total fixed deposit fees
- Total authorization fees
- Upfront fees incl. issuance
- Balance after upfront fees
- Average deposit
- Funding plus network outlay
Available = max(0, funding − issuance − percentage funding fee − fixed deposit fee × deposit count − authorization fee × purchase count) ÷ [(1 + purchase rate) × (1 + FX rate)]. Comparable loss = 1 − available ÷ funding. Total outlay = funding + additional network fees.
Assumptions: stablecoins and dollars are treated at 1:1. Issuance, funding and fixed authorization fees come out of the funding total. Purchase and FX charges compound. Network costs are additional outlays. Default rates are illustrative and are not a provider quotation.
Different fee ordering, minimum charges, tiered rates, refund rules or exchange rates change the result. Rewards, borrowing interest, monthly fees, restricted minimum balances and taxes are excluded and must be considered separately where relevant.
Why the same rate can produce different costs
- Fixed fees accumulate with frequency. At “4% + USD 1”, a USD 100 deposit costs USD 5, while a USD 1,000 deposit costs USD 41. The fixed-fee share differs.
- Purchase counts matter. Repeated small purchases or subscriptions can accumulate authorization fees faster.
- Currencies matter. A dollar-settlement card paying a non-dollar bill may have different charges from a dollar purchase.
- Minimum balances are distinct from fees. Separate money available to spend from money still owned but temporarily restricted.
Keep a verification record for each candidate
Record the source and your own verification separately so that later changes are easier to identify.
- Product, card range, application region and official links.
- Date checked, residence and document conditions, and KYC or KYB outcome.
- Funding assets and networks, limits, fees and minimum funding requirements.
- Merchant-test date, billing currency and charged amount; mark untested steps as untested.
- Refund, service-suspension, closure and balance-withdrawal procedures.
This record is more useful than a broad marketing claim. Our collected reference material does not mean we have personally applied for or tested every card.
Review payment and balance risks together
The operating platform, issuing institution and card network have different roles. A platform balance should not automatically be treated as a bank deposit. Reviews, policy changes, merchant restrictions or discontinued service can affect access to cards and funds.
Use accurate identity and residence information, understand exit procedures, and fund near-term payments. Advertising platforms separately review their accounts; successfully linking a card does not guarantee account approval.
Common selection questions
Does an accepted passport guarantee eligibility?
No. Residence, applicant type, issuing region and the specific product conditions must also be checked.
Is free issuance necessarily cheaper?
No. Compare funding, purchase, FX and fixed costs over the intended operating period.
Should I use TRC20 or ERC20?
First confirm the supported asset, network and address, then check the actual transfer cost and arrival conditions. A reference article's description is not a live network-fee quote.
Why is there no single best card here?
Eligibility and use cases change the available choices. Costs also depend on amounts, frequency and currencies. The workflow helps you check your own requirements.
