Abstract: A transaction card comprises at least one input button that receives a transactional input provided by a cardholder of the transaction card for initiating a secure card-based transaction. The input button is coupled to an electronic chip which when activated generates an electrical signal based on the transactional input. The electrical signal includes encrypted transactional data associated with the transaction card. A signal transmitter that is coupled to the electronic chip receives the electrical signal from the electronic chip, converts the electrical signal to one or more light pulses, and transmits the one or more light pulses to one of a terminal device or a user device for executing the transaction. The transaction is processed by an issuer of the transaction card based on the encrypted transactional data included in the one or more light pulses.

Abstract: Client side based data synchronization and storage is accomplished through a smart way of data off-lining coupled with a synchronization technique implemented on the client side that does not require any modifications to the server side. The customized client utilizes the server as a temporary placeholder for document synchronization. Attached documents to an item will be off-loaded from the client based on a predetermined policy. The clients make off-line copies of the items and documents. The server will maintain only the document store skeleton or metadata for such processed items. Any client which has not made an off-line copy of an item will pass a synchronization request via the server to the other clients so that at least one of its peers may upload the document onto the server. The requesting client can then retrieve the item from the server and synchronize/off-line that item on its local store.

Abstract: A universal way of providing contextual actions on electronic business forms or rich documents in a consistent manner irrespective of the document format or its hosting application utilizes metadata along with the actual data that will invoke the same context menu in any application. Actions can be taken on the document or GUI data field regardless of the hosting application or the document format. This seamless behavior is provided through first provisioning the context data in the document or the GUI field as a hyperlink with a custom protocol. The contextual information available at predetermined places in the document is preserved during document format transformation or document transition. Second, providing relevant actions to the user in a consistent manner at the predetermined places in the document is accomplished by creating and registering a Protocol Handler that will be invoked when a user clicks on the hyperlink.
