Today my son bought 7500 credits at a cost of about R1400 while playing GT racer on the galaxy tab . Sneaky blossoms. I know .... I should've known better. I do buy a few apps on the android market via google wallet.i have my cc details on my gmail account. Besides deleting my card details every time I buy an app is there another security measure I can put in place. Like a password before I hit buy.keeping the tab to myself is not an option.
