Search engine Google has been giving its app and mobile game developers a chinese burn until they use its Google Wallet service.
Google Wallet is not the payment service of choice for developers because it is more costly, but it seems that the search engine has been speaking softly and carrying a large stick to encourage its adoption.
The use of an integrated payment system has been one of the reasons that Apple did so well, and it seems that Google is trying to repeat the experiment in a bid to squeeze the maximum revenue from its Andriod operating system.
Google warned several developers in recent months that if they continued to use other payment methods, includingPayPal, Zong and Boku that their apps would be removed from Android Market.
According to the Sydney Morning Herald developers have been moaning that Google is telling them that it wants to simplify consumer payments, hoping apps-buying will rise and offset their higher costs.
But Google's payment service charges a higher cut per transaction than some rivals' and the fact the outfit is forcing developers to use it might anger any anti-trust watchdog that might be watching.
In one email sent to a developer in late August, Google said the developer had 30 days to comply, otherwise the developer's apps would be "suspended" from Android Market.
