RFID Card Reader, NFC Scanner

Turn your smartphone into a high-precision NFC & RFID diagnostic lab, transit card inspector, and multi-format tag writer!

Whether you are an RF engineer, developer, tech enthusiast, or daily commuter, this app provides an all-in-one toolkit to read, analyze, inspect, write, and clone 13.56 MHz RFID cards and NFC tags.

⚡ KEY HIGHLIGHTS & CORE FEATURES

🔍 1. Universal NFC & RFID Protocol Analyzer

• Multi-Standard Scan: ISO 14443 Type A & B, ISO 15693 (Vicinity), and FeliCa (JIS X 6319-4).

• Silicon Detection: Identify IC manufacturer (NXP, STMicroelectronics, Infineon, Sony, TI, etc.).

• RF Signal Diagnostics: UID (4/7/10 bytes), ATQA, SAK, ATS, historical bytes, 13.56 MHz frequency, and bitrate (106–848 kbps).

• EMV Payment Cards: Protocol inspection for Visa, Mastercard, AMEX, Discover, JCB, UnionPay (Application label, AID).

• E-Passports & Smart Cards: Read ICAO 9303 passport metadata and standard ISO 7816 smart cards.

🚇 2. Smart Transit Card Inspector & Balance Checker

• Live Balance: Check remaining card balance instantly with a single tap.

• Detailed Trip History: Boarding/alighting stations, transit & retail transactions, timestamps, and fare discounts.

• Global Transit Support: Compatible with Korean transit cards (T-Money, Cashbee, Rail+), Japanese FeliCa cards (Suica, PASMO, ICOCA), Octopus, and Calypso standards.

• Export Reports: Export commute logs and transaction receipts as formatted PDF or CSV tables.

✍️ 3. High-Performance NFC Tag Writer & 1:1 Cloner

• Multi-Format NDEF Encoding:

- 🌐 URL: Web links, social media, and app links (https, http, tel, mailto).

- 📶 Wi-Fi Quick Share: Create tap-to-connect tags (SSID, WPA/WPA2/WPA3, open networks).

- 👤 Digital Business Card: vCard contact sharing (Name, phone, email, organization, website).

- 📝 Plain Text: Custom text notes and smart home triggers.

• 1:1 Tag Cloning: Read source NDEF tag contents into memory and duplicate onto blank tags.

• Real-Time NDEF Capacity Meter: Visual payload vs. capacity progress bar (e.g., 28 / 504 B on NTAG215).

• Permanent Hardware Lock: Optional permanent Read-Only lock to prevent tag tampering.

• Target Tag Pre-Check: Free instant inspection of target tag capacity and writability before writing.

🧊 4. Interactive 3D Chip Architecture & Memory Map

• 3D Tag Structure: Visualize physical layers from antenna coil to microchip silicon and EEPROM.

• Hex & ASCII Memory Map: Inspect sector trailers, block data, access condition bits, and key status.

📊 5. Export, Search & Data Management

• History Archive: Search and organize past card scans with timestamps.

• One-Tap Export: Export memory dumps and card metadata via CSV, PDF, or clipboard.

📦 SUPPORTED CHIPS & STANDARDS

• NXP NTAG: NTAG213, NTAG215, NTAG216, NTAG203, NTAG424 DNA

• MIFARE Family: Classic (1K/4K), Ultralight, Ultralight C, DESFire (EV1/EV2/EV3), Plus

• ISO 15693: ICODE SLI / SLIX / SLIX2, Tag-it HF-I, custom vendor commands

• Sony FeliCa: Standard & Lite-S cards (IDm, PMm, System Codes)

• ISO 7816 / IsoDep smart cards & EMV contactless payment cards

🔒 PRIVACY & SECURITY GUARANTEE

• 100% On-Device: Scanned data is processed strictly in your device local memory.

• Zero Cloud Transmission: No card details, UIDs, or transaction logs are sent over the internet.

• Zero Tracking or Analytics.

ℹ️ REQUIREMENTS & NOTES

• Smartphone must have built-in NFC hardware enabled.

• Security Restrictions: Encrypted banking chips (cryptographic keys, CVV/CVC, offline PIN) have hardware-level protection per international standards.

• Factory UID Lock: Silicon manufacturer UIDs are factory-locked and cannot be rewritten. Standard writable NDEF tags (NTAG213/215/216) are recommended for writing/cloning.
