CENFC vs eSIM QR Code Scanner&Helper

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.

eSIM QR Code Scanner & Helper is a powerful offline eSIM QR Code Scanner and eSIM management tool tailored for digital nomads, travelers, and tech enthusiasts. Whether you want to extract core installation data or securely archive your purchased eSIMs for future reference, it provides you with the most professional, secure, and lightning-fast experience. Whether scanning via camera, scan eSIM QR Code from photos gallery, or pasting manually, the app instantly parses the real data behind the QR code. Clearly view hidden SM-DP+ core addresses, activation codes, putting you in full control of your data. Bought too many data plans and getting confused? Save your parsed eSIM parameters to your local "Archive" with a single tap, and add custom notes to each profile (e.g., "Japan 7-Day Trip", "Europe Backup"). All scan records are also automatically temporarily saved in "History" to ensure your digital assets are never lost. Export your eSIM details (including clear QR codes and core text parameters) as beautifully formatted PDFs or images with a single tap. This makes cross-device backup a breeze and allows you to elegantly share eSIMs with family and friends traveling with you. Beyond camera and gallery scanning, we offer a powerful "Manual Input" mode. You can freely input or edit SM-DP+ addresses and LPA strings, or even generate entirely new configuration profiles from scratch. Once parsed, the app intelligently helps you trigger the system's native eSIM activation process (depending on device support), or allows you to copy parameters with one tap for manual addition in system settings. We deeply understand the high sensitivity of your communication identity data. eSIM QR Helper is a 100% Local-Only App. We do not have any backend servers, and we will never collect, upload, or analyze your QR codes, gallery photos, or eSIM data. All parsing and saving processes are completed entirely offline on your device. Your data belongs absolutely and only to you.
