🛠️ Troubleshooting

SDK Initialization Fails

Problem: initPaySDK() returns error

Solutions:

Ensure Sunmi Payment Service is installed on device
Check permissions in AndroidManifest.xml
Verify all SDK libraries are in android/libs/

Clean and rebuild:

cd android
./gradlew clean
./gradlew build

Card Reading Not Working

Problem: checkCard() timeout or error

Solutions:

Check card reader hardware is functioning
Increase timeout value (e.g., 120 seconds)
Verify correct card type flags are used
Ensure card is properly inserted/swiped/tapped

EMV Transaction Errors

Problem: transactProcess() fails

Solutions:

Ensure AID and CAPK are properly configured
Verify terminal parameters are set correctly
Check EMV kernel version compatibility
Review transaction logs for details

Build Errors

Problem: Gradle build fails

Solutions:

Check android/app/build.gradle:

android {
    sourceSets {
        main {
            jniLibs.srcDirs = ['libs']
        }
    }
}
   
dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar', '*.aar'])
}

Verify all libraries exist:

ls -lh android/app/libs/
ls -lh android/app/libs/armeabi-v7a/

Check Java version (should be 17):
```
java -version
```

Runtime Errors

Problem: UnsatisfiedLinkError at runtime

Solutions:

Verify SO files are packaged in APK:
```
unzip -l app-debug.apk | grep "\.so$"
```
Check ABI compatibility (armeabi-v7a for most Sunmi devices)
Ensure jniLibs.srcDirs is correctly configured

Method Not Available

Problem: Method returns "unavailable" error

Solution: Plugin only works on actual Sunmi hardware. Cannot be tested on emulators or non-Sunmi devices.

SDK API Compatibility Update

Fixed SDK Method Signatures

This release fixes numerous API mismatches between the plugin and the actual Sunmi Pay SDK v2.0.17:

v0.0.5 (2025-12-06)

Security Update - PCI DSS Compliance

Security Improvements

✅ Removed all sensitive data logging (PAN, PIN block, track data)
✅ Added memory clearing for sensitive byte arrays
✅ Added PCI DSS compliance documentation
✅ Added EMVCo compliance documentation
✅ Security best practices section in README

Code Quality

✅ Fixed potential security vulnerabilities in PinPadModule
✅ Improved error handling without exposing sensitive data
✅ Added security comments throughout codebase
✅ Added CTX512 block operations

📋 TODO / Not Implemented Methods

The following methods from the original SDK API are not fully implemented due to SDK limitations or missing APIs. They currently return stub responses:

CardModule

| Method | Status | Description | |--------|--------|-------------| | at88scBurnFuse | ❌ Not Supported | SDK does not provide fuse burning capability. Returns error. | | at88scReadFuse | ⚠️ Partial | Replaced with at88scGetRemainAuthCount(). Returns remaining auth count instead of fuse data. | | ctx512bVerifyPwd | ❌ Not Supported | CTX512B password verification not available in SDK v2.0.17. | | ctx512bChangePwd | ❌ Not Supported | CTX512B password change not available in SDK v2.0.17. | | mifarePlusAESAuth | ⚠️ Workaround | SDK doesn't have separate AES auth method. Auth happens implicitly during read/write operations with key. Returns success placeholder. |

PinPadModule

| Method | Status | Description | |--------|--------|-------------| | getPinPadSerialNo | ❌ Not Available | Method not present in PinPadOptV2 interface. Returns "N/A". | | getPinPadVersion | ❌ Not Available | Method not present in PinPadOptV2 interface. Returns "N/A". | | isPinPadFeatureSupported | ⚠️ Stub | Method not present in SDK. Always returns { supported: true }. |

Planned Improvements

[ ] Investigate CTX512B operations in newer SDK versions
[ ] Add support for AT88SC fuse operations if SDK adds support
[ ] Add PinPad hardware info retrieval through alternative methods
[ ] Consider implementing Mifare Plus SL3 full protocol

Contributing

If you have access to SDK documentation showing these methods exist, please open an issue with the API details so we can implement them correctly.

🔐 Security & Compliance

PCI DSS Compliance

This plugin is designed with PCI DSS (Payment Card Industry Data Security Standard) compliance in mind:

✅ Data Protection

No sensitive data logging - PAN, PIN blocks, track data, and keys are never logged
Memory clearing - Sensitive data is cleared from memory after use
Encrypted storage - All keys stored in Sunmi's secure HSM

✅ Key Management

Secure key injection - Keys can be injected encrypted (ciphertext)
DUKPT support - Unique key per transaction capability
TR-31 key blocks - Secure key exchange format support
Key separation - TMK, PIK, MAK, TDK properly isolated

✅ PIN Security

Hardware-based PIN entry - PIN entered on secure PinPad
PIN block encryption - ISO 9564 formats (0, 1, 3, 4)
No clear PIN access - Plugin never has access to clear PIN
Anti-tampering - Sunmi hardware tamper detection

⚠️ Best Practices

// ✅ DO: Use encrypted keys in production
await SunmiPay.saveCiphertextKey({
  keyType: 2,  // PIK
  keyValue: encryptedKeyData,
  encryptIndex: 0,  // TMK index
  keyAlgType: 1,
  keyIndex: 1
});

// ❌ DON'T: Use plaintext keys in production
// savePlaintextKey() should only be used for testing!

// ✅ DO: Mask PAN in your application logs
const maskedPan = pan.substring(0, 6) + '******' + pan.substring(pan.length - 4);
console.log('Card:', maskedPan);

// ❌ DON'T: Log full card numbers
// console.log('Card:', pan);  // PCI DSS VIOLATION!

// ✅ DO: Clear sensitive data after use
let pinBlock = await SunmiPay.getPinBlock({...});
// ... use pinBlock ...
pinBlock = null;  // Clear reference

// ✅ DO: Use secure communication
// Always use TLS 1.2+ for online authorization

EMVCo Compliance

The plugin supports EMVCo Level 2 (L2) compliant transactions:

Contact chip - Full EMV contact specification
Contactless - EMVCo C-2 to C-8 compliance
Kernels - Visa payWave, Mastercard PayPass, UnionPay QPBOC, AmEx, JCB, Discover DPAS, MIR, RuPay
CDA/DDA/SDA - All authentication methods supported
Online/Offline - Both transaction modes

Security Checklist

Before going to production, verify:

[ ] No plaintext keys in production code
[ ] All sensitive data logging disabled
[ ] TLS 1.2+ for all network communication
[ ] AID/CAPK parameters from your acquirer
[ ] Terminal parameters properly configured
[ ] PIN encryption keys properly injected
[ ] MAC keys configured for host communication
[ ] Tamper response procedures defined
[ ] Key rotation schedule implemented

Compliance Documentation

For PCI DSS certification, you may need:

PA-DSS Report - Contact Sunmi for SDK certification documents
P2PE Validation - If using Point-to-Point Encryption
HSM Documentation - Sunmi's secure processor documentation
Key Injection Procedures - Document your key management
