Study notes
Brand detection
card brand detection · detect visa mastercard bin · card network from number
IIN rules identify Visa, Mastercard, Amex, Discover, JCB and more.
People search «card brand detection» when checkout fails or fraud review needs issuer context. I paste 6–8 digits into DN01 BIN Checker (BIN Checker) — never a full card number.
«Card brand detection from prefix» is a practical payments query. BIN lookup shows network, type and country when the prefix is in the local table.
Pair with Blacklist Checker for IP reputation and WHOIS for merchant domains — BIN answers issuer questions only.
For lab reports, screenshot the issuer row. For cron jobs use the API token — API access registration.
