US Patent 9547862 Electronic payment restriction

Methods and systems are provided for facilitating control of a child's purchasing of products from a merchant using a credit card, debit card, gift card, secure token, mobile device, or the like. A payment provider, such as Paypal, Inc., can authorized the purchase of a product from the merchant if both the child and the parent are checked in with the same merchant via one or more social networks (thereby indicating that the child and the parent are in or near the same store). This requirement for proximity between the child and the parent can provide the parent with an opportunity to more closely monitor purchases made by the child.
