Is it sensible to design a technology based around currently deployed capabilities or oshould the design assumptions extend to those capabilities that are likely to exist at the conclusion of the work or shortly afterwards? I know there are reasons that people might not want to use cameraphones in some industries, and that might well limit the utility of QR codes. However, it seems reasonable to anticipate cameraphone technology reducing in price and becoming more widespread in the next five years. _______________________________________________ Endymail mailing list [email protected] https://www.ietf.org/mailman/listinfo/endymail
