<p>Methods and systems can facilitate more convenient shopping by users of a payment provider, such as Paypal, Inc. A user can purchase a product simply by swiping a card without being required to enter additional information, such as the user's personal identification number (PIN). Thus, the checkout process at the point-of-sale can be performed more easily and quickly. More particularly, a user can open an app on a mobile device and sign in to a payment provider system using the app. The app can show merchants near the user. The user can select one or more of the merchants. Selecting a merchant allows the user to check in with the merchant. Checking in with the merchant can result in pre-authorization of a purchase by the user with the merchant.</p> |
