适用于Android的card.io SDK 扫描银行卡

card.io在移动应用程序中提供快速，轻松的信用卡扫描。

集成说明

1.卡片扫描要求

• 后置摄像头。
• Android SDK版本16（Android 4.1）或更高版本。
• armeabi-v7a，arm64-v8，x86或x86_64处理器。

为不满足这些要求的设备提供手动输入回退模式。

2.添加依赖

compile 'io.card:android-sdk:5.5.1'

3.添加权限及设置AndroidManifest.xml文件

4.示例代码

 1.设定一个按钮或其他组件来监听它的点击事件：

 @OnClick({R.id.btn_scan})
    public void setOnClick(View view) {
        switch (view.getId()) {
            case R.id.btn_scan:
                Intent scanIntent = new Intent(getActivity(), CardIOActivity.class);

                // customize these values to suit your needs.
                scanIntent.putExtra(CardIOActivity.EXTRA_REQUIRE_EXPIRY, true); // default: false
                scanIntent.putExtra(CardIOActivity.EXTRA_REQUIRE_CVV, false); // default: false
                scanIntent.putExtra(CardIOActivity.EXTRA_REQUIRE_POSTAL_CODE, false); // default: false

                startActivityForResult(scanIntent, MY_SCAN_REQUEST_CODE);
                break;
        }
    }

2.重写OnActivityResult(),去获得扫描结果：

 @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == MY_SCAN_REQUEST_CODE) {
            String resultDisplayStr;
            if (data != null && data.hasExtra(CardIOActivity.EXTRA_SCAN_RESULT)) {
                CreditCard scanResult = data.getParcelableExtra(CardIOActivity.EXTRA_SCAN_RESULT);

                // Never log a raw card number. Avoid displaying it, but if necessary use getFormattedCardNumber()
                resultDisplayStr = "Card Number: " + scanResult.getRedactedCardNumber() + "\n";

                // Do something with the raw number, e.g.:
                // myService.setCardNumber( scanResult.cardNumber );

                if (scanResult.isExpiryValid()) {
                    resultDisplayStr += "Expiration Date: " + scanResult.expiryMonth + "/" + scanResult.expiryYear + "\n";
                }

                if (scanResult.cvv != null) {
                    // Never log or display a CVV
                    resultDisplayStr += "CVV has " + scanResult.cvv.length() + " digits.\n";
                }

                if (scanResult.postalCode != null) {
                    resultDisplayStr += "Postal Code: " + scanResult.postalCode + "\n";
                }
            } else {
                resultDisplayStr = "Scan was canceled.";
            }
            Log.i("resultDisplayStr",resultDisplayStr);
            // do something with resultDisplayStr, maybe display it in a textView
            // resultTextView.setText(resultDisplayStr);
        }
        // else handle other activity results
    }
