NFC Tools: Tag Reader & Writer

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.

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.
