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: A method and a system for managing loyalty points of a user is provided. A plurality of loyalty accounts of the user are identified. Each of the plurality of loyalty accounts stores a first plurality of loyalty points. A conversion factor is determined for each loyalty account. Based on the conversion factor associated with each loyalty account, the first plurality of loyalty points of the corresponding loyalty account are converted to a second plurality of loyalty points. Further, a centralized account of the user is credited with a third plurality of loyalty points. The third plurality of loyalty points include the second plurality of loyalty points associated with each loyalty account. The credited third plurality of loyalty points are redeemable by the user.
