CENFC vs SegmentLens

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.

SegmentLens makes cutting out objects as easy as a conversation. Pick a photo and just say what you want—"the cat," "the sneaker on the left," "the plant on the table"—and SegmentLens finds the edges and lifts it out cleanly. Prefer not to type? Tap an object to select it, or draw a loop with your finger to grab a whole area. Powered by SAM's image-segmentation model, edges stay crisp and true to detail—no more pixel-by-pixel tracing. Features • Cut out by text: describe the object and let it find and segment it • Tap & lasso select: tap one, or loop a region for several • Multi-object detection: mark several objects at once with clear color-coded masks • Transparent PNG export: save straight to Photos with a fully transparent background—ready for stickers, posters, and product shots • Free sample scenes: try it instantly, no sign-in required • Import from your library or take a photo on the spot Great for E-commerce product shots, social stickers, collages, slide decks—anything that needs the subject kept and the background gone. About credits Processing your own photos uses credits (available via in-app purchase). The built-in sample scenes are completely free to explore. Imported photos are uploaded to the SegmentLens service for segmentation. • Lite — 150 credits • Standard — 550 credits • Pro — 1,600 credits • Max — 4,500 credits These are one-time purchases: nothing auto-renews and there is no recurring charge. Payment is charged to your Apple Account at confirmation of purchase. Credits are added to your account immediately and do not expire. Because credits are consumable, purchases are non-refundable except where required by law. Prices are shown in the App Store within the app and may vary by region. You can review past purchases in your Apple Account settings.
