Method and system for facilitating memory and application management on a secured token

Abstract: A system for facilitating memory and application management on a smartcard the system includes a client having a number of applications and a smartcard having specification logic allowing file structures and security and access conditions to be defined using a set of common commands Each application has a corresponding group of data on the smartcard An applet instance is created for each application and corresponding group of application data At the time of instantiation, the specification logic allows an application to specify the file structure and/or to specify security and access conditions for its group of data An application can utilize passcode and credential management so that a single passcode is used to access the smartcard regardless of whether the application utilizes the common commands to specify a file structure

Loyalty Program Parameter Collaboration

Abstract: Collaborative constituents collaborate to develop a loyalty program within a transaction processing system. Transmissions addressed to the collaborative constituents are formed and received from the collaborative constituents containing suggested parameters for the loyalty program. At least one remaining parameter for the loyalty program that a set of remaining collaborative constituents have agreed upon is determined. Another transmission addressed to each of the collaborative constituents in the set of remaining collaborative constituents is formed, the another transmission including the remaining parameters for the loyalty program.

Method and system for cross-issuer registration of transaction cards

Abstract: Disclosed herein is a method of providing one or more transaction card services to a holder of a transaction card, the method comprising receiving a registration code from the holder, wherein the registration code is associated with the issuer of the transaction card and with the transaction card, determining the issuer of the transaction card based on at least a portion of the registration code, transmitting the registration code to the issuer of the transaction card, receiving account information from the issuer, wherein the account information is associated with the registration code and with the transaction card, displaying at least a portion of the account information to the holder, receiving a verification value corresponding to the account information from the holder, and if the verification value is valid, permitting the holder to select one or more services in which to enroll.

In another embodiment, the transaction may be processed as a micropayment if the payee has previously been verified by the micropayment processing system. In a third embodiment, the transaction takes place using the payee's website.

Detecting changes in large data sets of payment card data: a case study

Abstract: An important problem in data mining is detecting changes in large datasets. Although there are a variety of change detection algorithms that have been developed, in practice it can be a problem to scale these algorithms to large data sets due to the heterogeneity of the data. In this paper, we describe a case study involving payment card data in which we built and monitored a separate change detection model for each cell in a multi-dimensional data cube. We describe a system that has been in operation for the past two years that builds and monitors over 15,000 separate baseline models and the process that isused for generating and investigating alerts using these baselines.
