Payment API for Android application
<p>I would like to integrate payment API for my android app but am still confused with different ways available. I checked PayPal API, Google checkout. In Google checkout there are several options like Email invoices, Buy Now buttons,etc. Actually my requirement is like, I need to purchase a voucher card from an Organization. So can you suggest me a suitable mechanism to achieve this requirement? Also that mechanism should accept all cards.</p>

<p>Any help will be greatly appreciated.</p>
