Tim Hortons' new all-in-one PIN pad technology supports all methods of payment on one device, including chip and pin, tap and swipe payments for acceptance of Tim Card, debit cards, credit cards and now mobile payments.
Login passwords can be replaced by a simpler PIN or even Microsoft's innovative picture login (where you tap on specific areas of an image), but there's no way to tell the OS to only ask for credentials after a certain period of inactivity.
