CENFC vs Grocery

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.

Grocery turns your shopping list into a smart, shared shopping assistant. Built for households and roommates who split the shopping, it keeps everyone in sync in real time — and helps you spend less while you're at it. SHARE LISTS IN REAL TIME Create as many lists as you need and invite family or roommates to shop together. Every add, check-off, and edit syncs instantly, so nobody shows up to the store with an outdated list. A live activity feed shows exactly who changed what. SCAN PRICE TAGS, INSTANTLY Point your camera at a price tag and let Grocery read it for you. It recognizes item names, member pricing, discounts, and per-unit pricing right off the shelf — no typing required. Save every scan to your price history so you always know what you paid last time. TRACK YOUR SPENDING Every scan builds a price history with trend charts, so you can see whether that "sale price" is actually a good deal. Browse, search, and compare prices across stores and trips. PRICE & UNIT CALCULATOR Compare two products side by side — per kg, per lb, per liter, per ounce — and instantly see which one is the better value. SMART STORE ROUTES Shop in the most efficient order. Grocery automatically groups your list by store section (produce, dairy, meat, and more), following a built-in warehouse-style layout — or build your own custom route. SPENDING INSIGHTS See your shopping trends over time — what you're buying most, and where your money is going. FLEXIBLE, YOUR WAY Organize items with built-in and custom categories, keep quick-add shortcuts for your most-purchased items, and get notified the moment a partner adds something new to a shared list. Sign in securely with Google or Apple. Your lists, your history, your pace. Grocery — smart grocery lists, made easy.
