<heading lvl="0">Abstract of Disclosure< / heading> An integrated suite of services for consumers, service providers and manufacturers in the pharmaceutical industry is disclosed. The present invention utilizes one or more of the NCPDP standard formats and adopts the switch for an integrated system of, for example, instant adjudication of prescriptions, consumer data warehousing and / or incentive rewards for the consumer. A participating consumer with one card, can instantly purchase pharmaceuticals and charge the transaction to a credit card and earn and apply savings dollars redeemable for pharmaceutical purchases. For a participating service provider, instant adjudication and instant validation of consumer eligibility can be performed. Moreover, a service provider may receive messages related to the patient's medications. Significantly, data is recorded for consumers even when consumers make the pharmaceutical purchase with cash. The system includes a unique card issued to participating consumers. The card is adapted to encode conventional credit or debit card information specific to the participating consumer so that the consumer can consummate a transaction for the purchase of pharmaceuticals without possession of an additional credit card. The system further includes a host processor coupled to the point of sale at the service provider through a leased line or public switch network or the like. When a customer performs a pharmaceutical transaction at the point of sale of the service provider, the host processor coordinates any benefits and data with other prescription benefit management systems through messages transmitted and received from any primary or secondary carrier systems. The host processor further is adapted to facilitate real-time adjudication of claims and checks for any dangerous drug-to-drug interactions. The host processor additionally facilitates any financial processing including the accumulation and redemption of any bonus dollars earned by the consumer. Furthermore, since the card used by the consumer can be encoded with credit or debit card information, the host processor determines the desired payment method and performs the actual financial transaction. Even if the transaction at the point of sale is a cash purchase, the consumer may desire to use his unique card for the accrual of bonus dollars. Therefore, data concerning the transaction (i.e., pharmacy number, prescription number, etc.) can be recorded even for transactions conducted with cash.

A transaction is conducted between a merchant site and a customer's electronic device using a payment processor. The merchant site is associated with a client-side application and a server-side application. The client-side application executes on the customer's electronic device. The client-side application electronically sends payment information retrieved from the customer's electronic device to the payment processor. The client-side application does not send the payment information to the server-side application. The payment processor creates a token from the payment information sent by the client-side application. The token functions as a proxy for the payment information. The payment processor electronically sends the token to the client-side application. The client-side application electronically sends the token to the server-side application for use by the server-side application in conducting the transaction. The payment information can thus be used by the server-side application via the token without the server-side application being exposed to the payment information.
