A shared 'universal' virtual shopping cart ('the cart') may be provided by a host to enable information sharing between multiple disparate electronic marketplaces provided by various merchants. The host may obtain user information via the cart to improve interactions with a user. The host may recommend an item to the user that is offered at a lower price and related to an item retained in the user's cart. The host may also recommend items based on a user's purchase history, such as complementary items (e.g., up-sell items) and items other users may recommend. In some aspects, the host may compile best selling lists based on data from multiple electronic marketplaces. The host may also perform user specific operations such as indicate an item in a cart is a duplicate of a previous purchase and monitor a price and/or available quantities of an item in the cart.

Systems and methods for authenticating a request submitted from a client device through a third party content provider to an electronic entity are described. In one embodiment, a method includes providing a trusted script to the third party content provider, passing a trust token to the third party content provider and to the client device, and, in response to a request submitted from the client device through the third party content provider, validating the trust token associated with the request with the token passed to the client device, and processing the request. The trusted script is configured to create a trusted window on the third party Web page displayed on the client computing device, receive a trust token from the electronic entity through the trusted window, and associate the trust token with requests submitted from the client computing device through the third party content provider to the electronic entity.

A payment instrument may be borrowed by a designated lendee and used to complete a financial transaction when made accessible by a lender via a lender's account. The lender may restrict use of the payment instrument by the lendee, such as by restricting a duration of use, setting purchase limits, etc. In various aspects, the lender may loan the payment instrument to the lendee without providing a physical card, actual card number, or other personal information. In some aspects, the lendee may be presented with an option to use a borrowed payment instrument when completing a purchase using payment information that is linked to the lender. The lendee may perform a validation process to confirm his/her identity and complete a purchase. In some aspects, the lender may require an authorization before the payment is finalized, which may enable the lender to terminate a payment request.

Disclosed are various embodiments for implementing secondary verification of user accounts through the use of near field communication devices. A first account code and first verification code are stored in a memory accessible to a computing device, wherein the first account code is associated with a payment instrument. A second account code is received in a charge request from a transaction client. A second verification code is further obtained from a client device. A determination is made as to whether to approve charging of an account based at least on whether the second verification code received in the computing device matches the first verification code.
