Abstract: A method for identifying payment credentials using a proxy electronic wallet comprises storing an account profile for a proxy electronic wallet that includes payment credentials for one or more payment accounts and account and/or payment credentials payment accounts associated with one or more paired electronic wallets. An account request is received from a digital entity that indicates the account profile, payment account identifiers are transmitted to a user computing device, a selection of a payment account is received from the user computing device, and a corresponding set of credentials in the account profile are identified. The credentials are then transmitted, where payment credentials are transmitted for use in a transaction, and account credentials are transmitted to an entity associated with the paired electronic wallet for use in identifying and providing corresponding payment credentials.

Abstract: Methods of transferring or receiving data using a multi-frame bar code are disclosed. A sequence of bar codes includes a plurality of bar codes displayed in a sequence, with each bar code in the plurality of bar codes being encoded with data and the sequence of bar codes conveying a coherent set of data. The sequence of bar codes is displayed, in a display device, such that only one bar code in the plurality of bar codes is displayed at any one time to constitute a three-dimensional (two spatial, one temporal) bar code when using a bar code. The bar codes are read, in a reader device, and then analyzed to identify each bar code in the sequence of bar codes. Each bar code is decoded to obtain the decoded data, which may then be combined into a coherent set of data.
