1. A non-transitory computer-readable medium storing instructions which, when executed on a computer system, cause the computer system to: provide a point bank, comprising a data store, the point bank using standardized input and output format structures communicated to sponsors of loyalty programs for communication with the point bank, the format structures to allow computing devices of merchants to interact in a compatible fashion with the point bank; store, in the data store, information regarding a first loyalty program; provide respective interfaces for a plurality of sponsors including a first merchant, each respective interface implemented as a website of the corresponding sponsor, and each website configured to interact with customers, wherein each interface communicates with the data store using a standard input and output protocol defined by the point bank; receive, via at least one interface over a network from a first computing device of the first merchant, a modification to the first loyalty program, wherein the at least one interface is established by the point bank; cause, via at least one interface, display of information regarding the first loyalty program on a plurality of computing devices of customers including a second computing device of a first customer, wherein the first customer manages, using the second computing device and via an interface established by the point bank, a reward account stored at the point bank; receive, via at least one interface, from the second computing device, a modification to implementation of the first loyalty program for the first customer; in response to receiving the modification from the second computing device, update the information regarding the first loyalty program in the data store; compare, by accessing the data store using a third computing device, transaction data in a request to process a transaction between the first computing device and the second computing device with respective requirements of a plurality of loyalty programs including the first loyalty program; access, via the data store, a customer profile of the first customer to implement loyalty program rules for the first loyalty program; process, by the third computing device, the transaction data using customer transaction history data, stored in the data store, and the loyalty program rules to compute a first loyalty currency amount and a second loyalty currency amount, the first and second loyalty currency amounts corresponding to different types of loyalty currencies; track the first and second loyalty currency amounts in the point bank; and in response to the transaction data meeting the requirements of the first loyalty program, award, by updating the data store using the third computing device, the first loyalty currency amount to a first loyalty currency balance of the first customer and the second loyalty currency amount to a second loyalty currency balance of the first customer.
