AI Overview
SuperCard X is a type of Android malware that facilitates fraudulent financial transactions by exploiting near-field communication (NFC) technology. It operates under a Malware-as-a-Service (MaaS) model, meaning that cybercriminals can access and utilize it for their own campaigns.
How SuperCard X operates:
- Social engineering: Victims are often tricked through fraudulent messages (like SMS or WhatsApp messages claiming to be from their bank) into calling a scammer. The scammer then attempts to acquire sensitive information, such as PINs, and convince the victim to install a malicious app disguised as a security tool.
- NFC Data Capture: The malicious app, often called “Reader,” requests NFC permissions and steals payment card information when the victim taps their card against the compromised phone.
- Fraudulent Transactions: The stolen data is transmitted to the attackers, who use a “Tapper” app to emulate the victim’s card and conduct unauthorized contactless payments at POS terminals or ATM withdrawals.
SuperCard X and Detection:
- Low Detection Rates: SuperCard X is designed to be stealthy, requesting minimal permissions and avoiding suspicious behaviors, making it difficult for traditional antivirus software to detect.
- Norton 360 and SuperCard X: Some sources indicate that SuperCard X currently exhibits a low detection rate among antivirus solutions. Cleafy reports that it is not currently detected by any antivirus engines on VirusTotal.
Protecting Yourself:
Since SuperCard X can be difficult to detect, proactive measures are crucial for protection:
- Be wary of unsolicited communication: Don’t click on links or call numbers provided in unexpected messages, especially those claiming to be from your bank.
- Download apps from official sources: Only install applications from trusted app stores like the Google Play Store.
- Verify with your bank directly: If you receive a suspicious communication, contact your bank using their official phone number or website to verify any claims.
- Monitor your accounts regularly: Check your banking and card statements frequently to detect and report any unauthorized transactions promptly.
- Disable NFC when not needed: Turn off the NFC feature on your device when you are not actively using it for payments.
- Consider using a trusted mobile security app: A reputable antivirus solution, such as Norton 360, can provide an additional layer of protection, although it’s important to be aware of the low detection rates for SuperCard X.
- Keep your device updated: Install the latest operating system and app updates to benefit from the most recent security patches.
Important Note: The information available about SuperCard X and its detectability by antivirus software is based on current research and reports. The threat landscape is constantly evolving, and new detection methods may be developed over time.

If your TAP card’s NFC function is not working, ensure your phone’s NFC is enabled and properly positioned over the card’s NFC chip. Also, confirm the TAP app is installed and updated, your card is activated, and the phone is not in a locked state. If issues persist, try clearing the app’s cache, checking for software updates, or contacting TAP support.
Here’s a more detailed breakdown:
- Check Basic Settings and Functionality:
- NFC Enabled: Make sure NFC is turned on in your phone’s settings.
- Phone Placement: The NFC chip in your phone is typically on the back, not the screen. Try placing the back of your phone against the card.
- Card Activation: Ensure your TAP card is activated for contactless payments.
- Phone Unlock: Confirm your phone is unlocked when attempting to use NFC.
- Troubleshoot TAP App and Card:
- TAP App Verify the TAP app is installed and updated.
- Card Activation: Check if your TAP card is activated for contactless payments.
- Media Permissions: Ensure the TAP app has the necessary media permissions.
- Card Limit: Make sure you haven’t exceeded the transaction limit for your card.
- Alternative Payment: If available, try using the physical TAP card or a different payment method to rule out issues with the card itself.
- Advanced Troubleshooting:
- Clear Cache: Clearing the cache for the NFC service and the TAP app might resolve some issues.
- Restart Phone: A simple restart can sometimes fix temporary glitches.
- Software Updates: Make sure your phone’s operating system and the TAP app are up to date.
- Check for Damage: Inspect your TAP card for any physical damage.
- Contact TAP Support: If problems persist, contact TAP support for further assistance.
- Specific to Mobile Payments:
- Google Pay: If you’re using Google Pay, ensure it’s set as your default payment app and that your device meets security requirements.
- Screen Lock: Some payment methods may require a screen lock for NFC payments.
- If using an iPhone
- NFC Location: For iPhones, the NFC module is near the top 1/4 of the device, according to Linq Help Center.
By systematically checking these areas, you should be able to identify and resolve the issue with your TAP card’s NFC functionality.

If the tap card NFC function is not working on your Android device, the first step is to ensure NFC is enabled and properly configured within your phone’s settings. Additionally, verify that your phone meets the necessary software requirements, such as Android version 5.0 or higher. If issues persist, try restarting your phone, clearing the NFC service’s cache, or even resetting network settings.
Troubleshooting Steps:
1. Enable NFC:
- Open your phone’s Settings app.
- Search for “NFC” or find it under “Connections” or “Wireless & Networks”.
- Ensure NFC is toggled on.
2. Check Software Compatibility:
- Make sure your phone is running Android 5.0 (Lollipop) or higher.
- You can find your Android version in Settings > About phone or System > About phone.
3. Google Pay Setup:
- If using Google Pay, ensure it’s set as the default payment app and that your card is added correctly.
- Verify that you have a screen lock set up.
- Make sure your phone is unlocked before attempting a payment.
4. NFC Antenna and Placement:
- Locate your phone’s NFC antenna, which is often near the top or back of the device.
- Ensure you’re holding your phone correctly, aligning the NFC antenna with the payment terminal.
- Try holding the phone closer to the terminal or for a few extra seconds.
5. Other Troubleshooting:
- Restart your phone.
- Clear the cache for the NFC service (Settings > Apps > See all apps > NFC > Storage & cache > Clear cache).
- Reset network settings (Settings > System > Reset options > Reset Wi-Fi, mobile & Bluetooth).
- Check for updates for Google Pay and your Android system.
- If using a case, ensure it’s not interfering with the NFC signal.
6. Bank and Card Issues:
- Confirm that your bank and card support contactless payments.
- You may need to enable contactless payment settings through your bank’s app or website.
7. Check for Developer Options:
- If you have developer options enabled, they can sometimes interfere with NFC functionality. Try disabling developer options and see if that resolves the issue.
If you continue to experience issues, it’s recommended to contact your phone manufacturer’s support or the payment app’s support for further assistance.
