US Patent 9247314 Cross-platform electronic shopping cart

A network device receives selected items for an electronic shopping cart as selected by a user. The electronic shopping cart is associated with a first access network platform. The network device identifies an abandonment of the electronic shopping cart and stores the selected items associated with a user account for the user to create stored cart items. The network device receives a cart inquiry indicating that the user has accessed a second access network platform and associates the stored cart items with the user on the second access network platform. The network device determines a highest priority item of the stored cart items based on the second access network platform, generates promotional instructions for presenting the highest priority item to the user on the second network platform, and sends the promotional instructions to the second access network platform.
