And, just something to consider about doing this in reverse: I'm beginning to see services where I can take a photo of a 2D barcode with my mobile and MMS it to a service and it returns info to me.
Example: In a server farm, I snap and send barcode to find out who what sites are on a machine and who "owns" it. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Barbara Ballard Sent: Thursday, May 08, 2008 2:53 PM To: Dante Murphy Cc: IXDA list; Karen Rush Subject: Re: [IxDA Discuss] Question about "scannable bar code" on a mobiledisplay On Thu, May 8, 2008 at 10:34 AM, Dante Murphy <[EMAIL PROTECTED]> wrote: > A client has asked about the feasibility of displaying a scannable bar > code on a mobile device, like a cell phone or PDA. > > > > Do most devices support the requisite resolution for this to work? Yes. But that's the wrong question. The correct question is, can the scanning device scan the bar code on the mobile phone? The answer to that question is ... in places where they are using visual scanners, like in much of Europe, it works fine; in the US, the laser scanners won't work. > How does the difference in size and scale of each pixel and display > impact the readability of the barcode? The various mobile bar code companies have worked that out nicely. I'd have to go research to see who is currently in the field. > Have you ever heard of or seen this in action? Yup. Just not really here. Okay, there are some installations on getting truly paperless airplane tickets: display the ticket data on the phone and the check-in scanner can read it. This is an environment in which the scanner is controlled, so it works better. (maybe movie tickets could do the same, but you'd be behind the competition) > How would the user get this barcode...would it have to be MMS, or would > the e-mail client be able to display this kind of content? Any which way a picture could get to a phone. MMS is a good answer (be sure you know how to really send MMS so they get to end users). A web site could do it (be sure to size the image so that transcoders don't resize it). An application could do it (but the user would have to get the application). I wouldn't do email unless you really wanted it on computers as well, because so few people have email on their phones. Unless you want to focus on a small set of phones. Consider also IM. -- Barbara Ballard [EMAIL PROTECTED] 1-785-838-3003 Design For Mobile 22-24 September http://design4mobile.mobi/ ________________________________________________________________ Welcome to the Interaction Design Association (IxDA)!
