Stability and memory improvements, safer back navigation, smaller and cleaner builds.
Read, write, copy, erase & lock NFC tags: URL, WiFi, vCard, geo. Batch write.
NFC Tools reads, writes, copies, erases and locks NFC tags — no account, and your tag content never leaves your phone. Write a WiFi card for your guests, a digital business card, a review link, a social profile or a URL sticker in seconds. When a tag doesn't work, the app tells you WHY: a compatibility guide and a Tag doctor explain the MIFARE Classic chipset problem behind most "tag not supported" reviews. NFC Tools is free with ads. NFC Tools Pro (monthly, 3-month, yearly with a 3-day free trial, or a one-time lifetime purchase) removes the ads and unlocks every Pro feature. Had NFC Tools before this update? You keep every Pro feature free, without ads. CORE TOOLS ARE FREE ✓ Full tag reader — serial number, technologies, tag type (NFC Forum Type 1–4, NTAG, MIFARE, ISO 15693, FeliCa…), used/total capacity, writable and lockable status ✓ Human-readable NDEF — URL, text, WiFi (SSID, security, password), vCard, phone, geo, SMS (also smsto:), email (subject and message split out), Smart Poster, Android app records; unknown types as hex, plus a Raw NDEF view ✓ One-tap actions on what you read — open a link, call, SMS, email, maps, add contact, copy or share ✓ Write 10 record types — URL, text, WiFi (standard WSC, 4 security modes), vCard, phone, geo, SMS, email, social profile (Instagram, TikTok, YouTube, WhatsApp, Zalo…, with a link preview) and launch app (opens an installed app or its Play Store page) — with field validation ✓ Size meter — payload in bytes and which tags it fits (NTAG213 / 215 / 216) ✓ iPhone check — warns when a tag will behave differently on iPhone ✓ Verify after writing — reads the tag back to catch faulty or fake tags that silently drop data ✓ Erase tags (with confirmation); copy one tag to many in a row ✓ Export a tag to an .ndef file and restore it later ✓ Tag doctor and compatibility guide — plain answers without writing: ready to write, blank, locked, MIFARE Classic or not NDEF, and which tags to buy instead ✓ Scan and write history — every scan, write, erase, copy and lock, stored on the phone. Filter, tap to copy. Scan entries keep only the tag type and a short summary, never a WiFi password, contact details or serial number ✓ Pause tag reading for 5, 15 or 60 minutes ✓ Robust scanning — a tag that slips away just asks you to hold it close again ADS AND PRO, PLAINLY • The free version shows a banner on the home screen and, at most every few minutes, a full-screen ad after a write or erase session is done — never while the app waits for a tag, never on read results. • Prices come from Google Play and are shown before you buy. Cancel a subscription any time in Google Play. • Not ready to buy? Watch a short video to unlock every Pro feature for 30 minutes (ads stay on).
