Check NFC Support & Test Tag Compatibility
Check NFC status and test tag compatibility instantly.
UtilitiesNFC Checker tells you in seconds whether your phone has NFC hardware, whether it's turned on, and whether a specific tag actually works with your device — see does my phone have NFC for the quick native-settings check on both platforms. Hold a tag to the back of your phone to see its type, memory size and supported technologies.
📖About This App
NFC Checker tells you, in seconds, whether your phone supports NFC, whether it's turned on, and whether a specific tag actually works with your device. The status dashboard shows NFC hardware availability and enabled/disabled state at a glance, with a one-tap shortcut to your phone's NFC settings. Hold a tag to the back of your phone to run a compatibility test and see its type, memory size, unique ID and supported technologies. Beyond checking and testing, NFC Checker also includes tools for working with NDEF tags directly: write text, URLs, Wi-Fi credentials, contacts and other data to a blank or rewritable tag, copy supported tag contents to another writable tag, and erase a rewritable tag so it can be reused (erase is available on Android; iPhone's NFC access is more limited). An optional Pro upgrade unlocks deeper tag analysis. Built-in guides help troubleshoot common NFC problems, such as a phone that reports NFC as unavailable or a tag that won't read. Available in multiple languages for iPhone and Android.

❓Frequently Asked Questions
What does NFC Checker do?
It checks whether your device has NFC hardware, verifies NFC is enabled, and tests whether a specific tag is readable and compatible with your phone.
My phone has NFC, but the app says it's unavailable.
Some phones ship with NFC turned off by default, and some carriers or device-management profiles restrict it. Use the app's Settings Shortcut, or go to your device's Settings > Connected devices / NFC, to confirm it's switched on.
How do I test an NFC tag?
Open the checker screen, start a scan, and hold your phone near the tag. The app reports whether it read the tag successfully and shows its compatibility.
What tag information can I see?
Tag type (such as NTAG or MIFARE), memory capacity, unique ID, and the technologies and data format the tag supports.
Can this app write to NFC tags?
Yes. NFC Checker includes a Write tool for compatible, unlocked NDEF tags — text, URLs, Wi-Fi credentials, contacts and more — plus Copy and Erase tools for managing tags you already own.
Can I copy or erase any NFC tag?
No. Copy and Erase only work with supported, writable NDEF tags; protected payment, transit, identity, hotel-key and access-control tags can't be copied or erased. Erase is available on Android; it isn't offered on iPhone.
Why can't my phone read certain tags?
Tag support depends on both your phone's NFC hardware and the tag's technology. iPhone reads NDEF-formatted NFC Forum Type 1–5 tags but not MIFARE Classic, and some proprietary or encrypted tags aren't readable by any phone's standard NFC stack.
Does NFC work when my screen is off?
On most phones, NFC scanning requires the screen to be on and the app or reader mode active. Some Android phones support limited background tag reading; iPhone requires the Checker app to be open in the foreground.
Is NFC Checker free?
The app is free to download and use for status checks, tag testing and the Write/Copy/Erase tools. An optional Pro upgrade is offered for deeper tag analysis; your store confirmation screen shows current pricing and terms before purchase.
