Abstract: The present invention provides an optical waveguide, comprising: an input end for receiving a divergent beam; an output end for outputting an illuminating beam; a longitudinal cavity extending from the input end till the output end; a first pinhole located at a first predetermined distance from the input end within the said longitudinal cavity for receiving the divergent beam and for generating a fringe pattern, said first pinhole bifurcating the longitudinal cavity into a first and a second light propagating regions, the longitudinal cavity forming the first light propagating region being provided with a reflective coating on its internal surface to enable internal reflection of the divergent beam; and a second pinhole located at the output end for receiving the fringe pattern thus generated by the first pinhole and for outputting the illuminating beam corresponding to a central bright fringe contained in the said fringe pattern via the output end.

Abstract: An e-wallet service allows a consumer to retrieve a list of merchants selling goods and services specified by the consumer, see reviews by other consumers who conducted transactions with the merchants on the retrieved list; select a merchant from the retrieved list and an account to pay for a staged transaction and a corresponding token for the staged transaction with the selected merchant, conduct the staged transaction with the merchant by the submission of the token to the merchant as form of payment; and use the token, after conducting the staged transaction with the selected merchant, to gain access to a social media portal and input the consumer's opinion about the selected merchant's performance of the staged transaction.
