This is big news for web publishers based in India, as till now, AdSense used to pay only via cheques, which not only took long time for publishers to receive their payments, but was fraught with issues like non-delivery of cheques due to courier partner issues.
Even under normal circumstances, the cheques arrive nearly 2 to 3 weeks later than what they are supposed to. For example, the earnings made by publisher in month of September are released by end of October and then it additional two to three weeks to reach publishers. With EFT in place, the payments would be done in not more than 2 days after earnings are finalized.
Though Google has not announced this officially, a thread on Google product forums clearly points to the fact that they are testing EFT payments for India based publishers. The thread was started by a user "Om Software" to protest the delay in delivering the Adsense payment checks in India. Here is the reply from authorized representative under the username "Adsense Pro Payments."
