Unfortunately, you can’t transfer funds to another Google Play account. The online store doesn’t allow the exchange of currency or gift card codes. Each user has to submit their own information to complete a transaction, regardless of the payment method. If you want to share your content, however, you can create a “Family Library.” That way, your loved ones will be able to access some of your purchased items, but that’s pretty much it. Also, the feature only works with movies and apps. Any music you have on your account will be off-limits.
