现在有好多扫描识别银行卡号的SDK都是收费的，但是也有不收费的，但是有一定的问题，就是那种印刷的银行卡号扫描不出来，希望哪位大神指导原因给解释下，这个不收费的SDK就是card.io-Android-SDK，githubdi地址
使用方式很简单，更多介绍可以看GitHub 使用文档：
首先导入依赖：compile ‘io.card:android-sdk:5.5.1’
然后在你需要调用拍照的地方加上一下：
代码语言：javascript复制Intent scanIntent = new Intent(this, 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
// MY_SCAN_REQUEST_CODE is arbitrary and is only used within this activity.
startActivityForResult(scanIntent, MY_SCAN_REQUEST_CODE);在onActivityForResult中接收结果：
代码语言：javascript复制@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == MY_SCAN_REQUEST_CODE) {
String result;
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()
result = "Card Number: " scanResult.getRedactedCardNumber() "n";
if (scanResult.isExpiryValid()) {
result = "Expiration Date: " scanResult.expiryMonth "/" scanResult.expiryYear "n";
}
if (scanResult.cvv != null) {
// Never log or display a CVV
result = "CVV has " scanResult.cvv.length() " digits.n";
}
if (scanResult.postalCode != null) {
result = "Postal Code: " scanResult.postalCode "n";
}
} else {
result = "Scan was canceled.";
}
Log.e("resultdispalyStr----",result);
}
}以上就是本文的全部内容，希望对大家的学习有所帮助。
