A method of a commerce ads engine to improve secure transactions between a merchant and a customer, the method comprising: storing, by the commerce ads engine, a fragmented authentication token received from a tokenization platform, the fragmented authentication token associated with a payment checkout platform such that the fragmented authentication token, when passed to the payment checkout platform, authenticates a checkout process at the payment checkout platform only one time before expiring; transmitting, by the commerce ads engine, the fragmented authentication token to a customer device associated with the customer, such that the fragmented authentication token is now uniquely associated with the customer device; storing, by the commerce ads engine, merchant offer data associated with an offer to sell a product of a merchant, the merchant offer data including an offer ID that uniquely identifies the merchant offer; transmitting, by the commerce ads engine, the merchant offer data to an advertisement content network, wherein the merchant offer data is converted into a digital advertisement about the merchant offer to sell the product and includes a digital link configured to pass along the offer ID to the customer device when the digital advertisement is selected by the customer; receiving, by the commerce ads engine from the customer device, the offer ID passed from the digital advertisement, and an authenticated fragmented token, the authenticated fragmented token comprising the fragmented authentication token that is authenticated by an authentication process with the customer device; determining, by the commerce ads engine, that the customer initiated an acceptance of the merchant offer, based on: reliably correlating the received offer ID with the merchant associated with the merchant offer, and reliably correlating the received authenticated token with the customer device it is associated with; accessing customer payment information associated with the customer, based on verifying the customer using the authenticated fragmented token; accessing merchant account information associated with the merchant, based on verifying the merchant using the received offer ID; and initiating, by the commerce ads engine, a secure checkout procedure with a payment checkout platform for the purchase of the offered product, by transmitting to the payment checkout platform at least a subset of the merchant offer data, the merchant account information, the customer payment information, and the authenticated fragmented token. storing, by the commerce ads engine, a fragmented authentication token received from a tokenization platform, the fragmented authentication token associated with a payment checkout platform such that the fragmented authentication token, when passed to the payment checkout platform, authenticates a checkout process at the payment checkout platform only one time before expiring;
