Description
CENFC is an advanced NFC toolkit for iOS. Scan, identify, dump, and analyze NFC tags — all processed locally on your device with zero data collection.
SCANNER
Instantly identify NFC tags through ATQA/SAK lookup and protocol probing. Supports ISO 14443, ISO 18092 (FeliCa), and ISO 15693. Accurately detects chip variants and card families, displaying UID, protocol details, and iOS operability status at a glance.
MEMORY DUMP
Read the complete memory of any operable NFC tag. Browse page-by-page and block-by-block breakdowns with parsed NDEF content. Export dumps in hex, JSON, or raw binary for forensic analysis or backup.
NDEF READ & WRITE
Create, read, and write NDEF messages to compatible tags. Supports Text, URI, Smart Poster, MIME, and External record types. Build multi-record messages from scratch and write them directly to any writable tag.
PASSPORT READER
Read electronic passports and travel documents (eMRTD) via BAC authentication. Enter MRZ data to securely access data groups — including MRZ, face image, additional personal details, and security objects. Perform Active Authentication to verify chip genuineness.
RAW COMMUNICATION
Send custom APDU commands directly to NFC tags. Full ISO 7816 APDU support with complete command logging — built for developers and researchers.
PROTOCOL TOOLS
Hex Converter — Convert between hex, decimal, binary, and ASCII
CRC Calculator — Compute CRC_A and CRC_B per ISO 14443-3
ATQA/SAK Lookup — Identify card type from raw protocol parameters
Access Bits Decoder — Decode sector-level permissions
BER-TLV Parser — Parse and visualize TLV data structures
OPEN SOURCE & PRIVACY FIRST
CENFC is fully open source — inspect every line of code yourself. Every NFC operation runs entirely on-device. No data leaves your phone. No servers. No account required.
Requires iPhone 7 or later with NFC capability.
