Checked and verified
“checked” is the last time the source was found unchanged; “verified” is the last time the value was read from the source. “updated” is the last real value change.
What does the double s mean?
ss = sourced & synced. sourced: every value has a source, a quote and a snapshot. synced: every value is compared with its source continuously and carries its check date.
Sponsoring and affiliate links
Sponsored slots are labelled and have no influence on score or ranking. Affiliate links are marked.

Alerts and early warning
Alerts come from the same sourced data as the pages: changelog (fees, rewards, features), the provider's promotions, incidents, licences, the card's status and news rated by our AI. Every alert has a direction (good, bad, neutral) and a severity; negative alerts from severity “high” (e.g. licence revoked, hack, card discontinued) go out at once, everything else in one mail at 7 am your time. Every mail links the evidence. Sign-up with confirmation only (double opt-in), one-click unsubscribe, deletion 30 days after unsubscribing.
