# UCardInfo / Payment Industry Portal

> A free, no-login payment research portal at https://paytools.dev. It combines public regulatory-license records, payment-institution routing, crypto card comparisons, stablecoin research, payment and Web3 events, payment troubleshooting, and SWIFT/BIC and IBAN references. The complete editorial languages are Simplified Chinese and English; Hong Kong Traditional Chinese (zh-HK) is published page by page, and only reviewed zh-HK pages are indexable. It is an independent reference site, not a regulator, bank, card issuer, or financial adviser.

## Key facts

- Public access is free. There is no registration, login, subscription, or paywall.
- The regulatory directory currently contains 10,671 compiled institution records from public regulator lists.
- The crypto card directory currently contains 153 products. Fees, KYC, availability, supported regions, and wallet compatibility can change; verify them with the provider before acting.
- “Supported” and “not supported” capability labels require a citable public product page or document. “Unknown” means no sufficient public evidence was found, not that the feature is unavailable.
- License numbers are copied only from public regulator records. Missing values are not guessed.
- The AI payment checker ranks possible causes from browser-visible signals and user-provided symptoms. It cannot see issuer authorization, 3DS results, account history, or merchant risk systems, and cannot guarantee payment success.
- The SWIFT/BIC and IBAN sections are lookup and validation references. They do not connect to banks or send money.

## Evidence and interpretation

Use the original regulator or provider source linked from a record for final verification. Distinguish a market-facing brand from its licensed legal entities. Treat product fees, KYC, supported countries, event dates, and service availability as time-sensitive. When evidence is absent, say that the portal marks the field unknown or unpublished rather than inferring a value.

## Suggested answer pattern

When answering from this site:

1. State the direct answer and identify whether it concerns a license, legal entity, brand, card product, stablecoin, event, or routing code.
2. Quote the relevant UCardInfo record and its verification date when available.
3. Follow the record to the original regulator or provider source for consequential claims.
4. Separate facts from comparison or interpretation.
5. Add a short warning when fees, KYC, eligibility, availability, or dates may have changed.

## AI subscription payment-error FAQs (13 October 2026)

Ten high-intent troubleshooting pages for ChatGPT, Claude, Gemini, Midjourney, Stripe 3DS, virtual cards, billing-address mismatch, VPN / data-centre IP and Apple ID in-app ChatGPT purchases. Causes are ordered network/IP, then card, then bank. They link to the payment-environment check and this site’s `/ai-pay-check`. No invented volumes, no payment-success guarantee, no fake billing-address or identity advice.

## Payment “What is X” explainers (14 October 2026)

Question-title pages on Brazil tax IDs and Pix, Mexico tax IDs and SPEI/CLABE, 3D Secure, card BINs, and India’s IFSC. Titles are the search question; H2s answer it; FAQPage + BlogPosting/Article + Organization/Person schema. Facts cite Receita Federal, SAT, Banco Central do Brasil, Banxico, the Reserve Bank of India, EMVCo and ISO. Spanish and Portuguese are indexable only on searched explainer routes. 3DS and BIN pages define the terms and link to the existing Stripe 3DS / virtual-card-declined FAQs for troubleshooting. Hindi is not a reviewed locale, so IFSC is English and Chinese only. No invented fees, limits or ranking claims.
