Important Notice

*Why some cards cannot be emulated: Android HCE (Host Card Emulation) always generates a random UID — the reader will see a different UID than the original card. Mifare Classic technology is NOT supported by Android HCE, which means cards like Flazz, e-Money, Brizzi, TapCash, and transit cards (KRL, MRT, LRT, Transjakarta) cannot be fully emulated. This is a hardware security restriction, not a limitation of the app.

User Guide

Step-by-step instructions to scan, save, and emulate NFC cards

Installation & First Launch

Download NFC Card Manager from Google Play Store or GitHub. Install and open the app. The main screen shows:

Virtual NFC Card banner at the top with Scan and Emulate buttons.
Saved Cards section listing all your previously saved cards.
User Guide button for quick reference anytime.

Scan an NFC Card

To read a new NFC card:

Tap the SCAN CARD button on the main screen.
A dialog appears: "Tap your NFC card to the back of the phone..."
Place your NFC card on the back of your phone (near the camera area on most devices).
Hold steady until the card is detected and data is read.

Tip: Make sure NFC is enabled in your Android system settings before scanning.

Review & Save Card Data

After scanning, the app displays detailed card information:

UID: Unique identifier of the card (e.g., 3F C4 86 4C).
Supported Technologies: IsoDep, NfcA, MifareClassic, NdefFormattable, etc.
Card Details: ISO-DEP historical bytes, NFC-A ATQA/SAK, Mifare Classic type, size, sectors, and block data.

Tap SAVE CARD to store it with a custom name, or CLOSE to discard. You can also tap EMULATE NOW to start emulation immediately without saving.

Manage Saved Cards

Your saved cards appear in the main screen list with:

Card Name: Custom name you assigned (e.g., "one dimsum flash", "ktp john").
UID: Displayed for quick reference.
Technology: Shows supported tech types.
Date: When the card was saved.
Actions: Edit (pencil), Emulate (play), Delete (trash).

Tap any card to view full details, or use the action buttons for quick operations.

Emulate a Saved Card

To use your phone as a virtual NFC card:

Tap the play button on any saved card, OR tap the EMULATE button at the top and select a card.
A green "EMULATION ACTIVE" status screen appears.
Tap your phone to the NFC reader now — your phone will act as the selected card.
Tap STOP EMULATION when finished.

Note: Emulation requires your device to support Host Card Emulation (HCE). Most modern Android devices are supported.

Understanding Limitations

NFC Card Manager is powerful but has important limitations due to Android hardware:

Cannot clone real UID: Android HCE generates a random UID — readers see a different UID than the original card.
Cannot emulate Mifare Classic: Cards like Flazz, e-Money, Brizzi, TapCash, and transit cards (KRL, MRT, LRT) use Mifare Classic which is NOT supported by Android HCE.
Emulation success varies: Depends on the NFC reader and card type. Some readers may not accept emulated cards.
