Source hierarchy
We prefer issuer documentation, product terms, official help centres, network documentation and regulatory disclosures. Reliable secondary sources may help identify changes, but material claims should be confirmed against a primary source whenever possible.
Normalization and review
Source wording is converted into consistent fields so readers can compare like with like. Dates, currencies, regional restrictions and conditional fees are preserved where they materially affect meaning.
Published information is reviewed periodically and when a credible correction is received. The updated date describes our record, not necessarily the date on which an issuer changed its product.
Unknown and conflicting information
We do not turn missing information into a zero or a positive claim. If sources conflict or a fact cannot be verified, the field may be marked as not disclosed until the issue is resolved.
Rankings and commercial relationships
Pinned cards are editorially selected for visibility and are not ratings. Other cards can be sorted by publication date or name. The current site has no affiliate programme and does not sell ranking positions.
Corrections
Readers and providers can submit a correction through the contact page. We review supporting evidence and update the structured record when the change can be confirmed.
