You can't exactly use Google Wallet everywhere you go just yet, but if you do use it often enough to warrant semi-regular transfers from your bank, then you'll love its latest update. Now, you can activate recurring bank transfers, even pick the amount and the schedule (say, once a month or so) you want, to automatically replenish your digital dollars. That's especially useful if you depend on the physical Wallet card, which spends that balance every time it's charged. But in case Wallet balance doesn't matter as much -- say, you have an NFC-enabled Android phone and prefer to tap and pay mostly using credit -- then, you can also just program the app to let you know if it's almost out of cash. These features are available for both iOS and Android, as you can see after the break, but you can only use the tap-and-pay option if your NFC phone runs KitKat or higher.
