CENFC vs iTerm2 Buddy

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.

iTerm2 Buddy connects your iPhone or iPad to iTerm2, the popular terminal for macOS. Once paired with your Mac, it lets you keep an eye on your terminal and act on it from the couch or on the go. REQUIRES A MAC iTerm2 Buddy is a companion app. It works only after pairing with iTerm2 and the free companion plugin on your Mac. Pairing takes a few seconds: your Mac shows a QR code, you scan it, and confirm a short code on both devices. WHAT YOU CAN DO - Live terminal: watch a session update in real time, exactly as it looks on your Mac, including colors, inline images, and full-screen apps like vim, htop, and less. - Type and control: bring up a keyboard with the terminal keys you need (Esc, Control-C, Tab, arrows, function keys) and send input to a session. A composer lets you write longer commands and send them all at once. - Chat with an AI agent: message an assistant that runs on your Mac and can act on your sessions, open windows, run commands, review changes, and report back. Approve sensitive actions right from your phone. - Notifications: get a push when the agent replies or needs your approval, so you can step away and return when it matters. - Voice input: dictate messages with on-device transcription. Your audio never leaves your phone. PRIVACY AND SECURITY Terminal content shared between your Mac and your phone is end-to-end encrypted with the Noise protocol, so only your own devices can read it. There is no account and no advertising, and the app includes no third-party tracking. FREE iTerm2 and iTerm2 Buddy are free.
