## What is TapTagNFC?

TapTagNFC is an NFC tag reader, writer, diagnostic, and manager for iPhone. Create and manage compatible NDEF content, then write frequently used information to supported physical tags.

KEY FEATURES
• Read, write, and diagnose compatible NFC tags; inspect UID, capacity, chip, writable, and lock states
• Support NDEF, ISO 14443, ISO 15693, ISO 7816, and FeliCa; actual operations depend on the device, tag type, and OS support
• Create web, text, phone, email, SMS, Wi‑Fi, location, vCard, social profile, and door access content
• Encrypt, password-protect, erase, save, template, and batch-write tags where supported by compatible tags
• Share and parse URLs or link text from Apple Maps, Google Maps, YouTube, TikTok, Bilibili, and X into web, location, or platform-link content; share or select a contact to create a vCard. Results depend on the format provided by the source app
• App Clip provides cards, connect, share, promote, and verify experiences without installing the full app
• In supported environments, emulate a tag so another compatible device can read NDEF content provided by iPhone

PURCHASES AND AVAILABILITY
The free version contains ads and limits daily writes, saved tags, and record counts. Some advanced features require a one-time In-App Purchase. Available benefits and local prices are shown on the in-app purchase screen.

Tag emulation requires a paid unlock and Apple’s HCE entitlement. It is available only on supported iPhone models, OS versions, system environments, and regions. Door access connections, encryption, password protection, and other advanced operations also depend on compatible tags, devices, service configuration, and system permissions. The app checks availability and displays relevant guidance before use.

PRIVACY
NFC content, records, and saved tags are processed on device by default. The Share sheet and Contacts are accessed only when you use the related features. If optional iCloud backup is enabled in the current version, it is provided through Apple iCloud. Ads in the free version are provided by Google and may process ad-related data according to your region, consent choices, and system privacy settings. See the in-app and website privacy policy for details.
