Source layers
- Official issuer and platform help: specific features and rules, with links and check dates on topic pages.
- Supplied reference snapshots: the 22-card directory mainly follows the supplied U Card Guide page, dated November 10, 2026 and collected on November 11, 2026.
- Our explanations and examples: workflows, checklists and calculator defaults are not provider quotes.
Cost assumptions
Directory losses follow the reference scenario: first virtual-card issuance, one 1,000 USDT funding and ten foreign-currency payments, excluding gas. Calculator inputs are adjustable; defaults are illustrative. Monthly subscriptions, team charges, interest and merchant-specific fees may require separate budgeting.
Unknowns and contradictions
- Undisclosed fees stay unknown rather than zero.
- “≥” remains a lower bound rather than a complete cost.
- No explicit mainland exclusion does not establish approval.
- Conflicting pages require product-specific checking rather than silently choosing a convenient claim.
- Terminated entries remain clearly marked for historical identification.
Ratings and testing
We do not maintain a verified card-scoring model or import another site’s ratings, review counts or community sentiment as our own results. Unless explicitly documented, we do not claim card-provisioning, purchase or refund tests, or continuous automated verification.
External links and updates
Historical reference articles may contain referral or promotional links. Placement is not a quality guarantee. Topic references include their check dates; this update does not establish that all historical product parameters have been refreshed.
