Android SDK scan credit card but does not produce output.

[muraliandroid]

I am using card io Android SDK library (version 5.0.0) in Eclipse. The application opens the scan page and it scans the credit card but does not produce output ( showing credit card information). Please see the image URL of the screen short (scanning credit card): http://i.imgur.com/GFV3IKG.png Please help me on find out my mistake. I have tested my application on Samsung S4,Moto E, Sony xperia Z and Samsung S3. My credit card number provider is "ICICI Bank" and number starts with 4.

Note: I have created Android project in Eclipse and please see the following link how I used processor libraries in my project (it may has problem) : http://i.imgur.com/iicjKjm.png

Does the phone vibrate when the card is recognized? If not, the card is not actually scanned. Rather, it is merely highlighting the edges of the card, while card.io attempts to find the number. This is most likely due to the card not having embossed numbers, or not a pattern that we support. Have you had any luck in iOS with the same card?

[muraliandroid]

The mobile phone does not vibrated when scan the credit card. what you mean by pattern here (I assumed its card type supported, listed in the http://card-io.github.io/card.io-Android-SDK/io/card/payment/CardType.html page. am I right?). My credit card is powered by VISA. currently we do not have iOS.

[braebot]

Ok, then card.io is not recognizing the card. I assume it starts with 4? Is the card number 16 digits long? Does card.io scan any other cards in your possession?

[muraliandroid]

Yes, my card starts with 4 and its 16 digits long.

[muraliandroid]

I have checked in iOS with same card. its works but it takes long time to recognize and shows the output and some time does not recognize even if hold for a long time. In Android case it does not work. please help me. Please see my Logcat details for Android: (Tested on Sony Z)

[braebot]

Have you tried running the included Android tests on this device? I've found that to be a good indication of whether or not the device will quickly pick up the device.

[braebot]

In addition, please keep in mind that card.io can only scan traditional, embossed numbers. As you've seen with Android, not all processors/cameras can successfully detect all cards.

[roscrazy]

hello you all. I faced the same problem. I 've tested on Note 3(Android 4.4) and Nexus 7 running Android 5.0.1. Do you guys have found out how to resolve the problem here ? Please help me.

[braebot]

When you are testing with card.io 5.0.+, did you update all the libs files, in addition to the .jar file? If you're using eclipse, you may have forgotten this step, and the cards will not scan as a result. See https://github.com/paypal/PayPal-Android-SDK/issues/161 for another customer with this issue.

[roscrazy]

hi @braebot ,

Thank for your quick response. But I 've just pulled the latest source last night. At the beginning tested with the sample code here https://github.com/card-io/card.io-Android-SDK (tested with Android studio, have this line in gradle compile 'io.card:android-sdk:5.0.0') , but it did not work then I pulled the libs from https://github.com/card-io/card.io-Android-source then built the sample app. But I got the same problem too. Any suggestion please

[muraliandroid]

Hi, I have tested my sample application again on yesterday , but it never scan my credit cards. I am sure, I have placed library files correctly in libs folder as shown in your Paypal example (only difference is, I have used cardio.jar file which got from extracting ".AAR" file and renamed classes.jar into cardio.jar). Please help me and let me know if your want to see my sample application. Please check out my libs folder created using Eclipse, it may contain problem. http://i.imgur.com/iicjKjm.png

[braebot]

Huh, so some folks are even having problems with the sample app, using Android Studio? If you are still having issues with Android Studio, please share your project on GitHub and I can have a look.

As for the eclipse issue, please ensure you're using the latest .so files, as well as the classes.jar extracted from the .aar file. Beyond that, I'm afraid we're going to have to rely on the community for eclipse support, as we only use Android Studio and Gradle.

[roscrazy]

hi @braebot ,

Here is the project as your request : https://github.com/roscrazy/TemporaryCard.ioSample I only downloaded your sample project and trying to test it. I tested the card with iOS and it can read. But for Android, there are no signal ... Please help me take a look. And could you kindly send me an APK which can read your cards. Then, I can test with my cards. Sincerely.

[braebot]

@roscrazy, the project you shared does indeed scan my card when I install the app (after adding the necessary gradle/ directory contents). It could be your device that is not supported. Can you paste some logs? What is the behavior you notice?

[roscrazy]

hi @braebot ,

So sorry, I got the app working now. I tested with the other cards, and it work (but It take long time to recognize). Maybe because my device's camera and the card( the card that I mention before) does not work well together. Thank you very much for your supporting.

[maha1010]

am using card.io to scan credit and debit cards.scanning screen opens but not producing result even my device not vibrate

[pravin-mindstix]

@maha1010 : are you scanning embossed card? I am not sure but, AFAIK we can scan only embossed cards using card.io.

[maha1010]

can any one guide me to scan all debit and credit cards please

[MinaMedhatKamel]

I have the same problem , did anyone solve it ?

[rdonik]

hey! Did anyone solve this problem?
