Hi all - I have a client asking me to create a bar code scanning app that would be for trade shows.
They register people at the door, print out a badge with a bar code, and then exhibitors can scan their badge to get their registration ID.
Then, the exhibitor goes online, posts their scanned IDs, and downloads the contact info.

Could this be done with Gideros? How much would someone charge me to create this?

The reason I want to see it done in Gideros is 1) I currently use Corona SDK 2) This would be a good project to see Gideros in action 3) I'm hoping to see it done with Gideros in mostly LUA so I can tweak it 4) I would like to be able to see an add on project first hand.

As far as bar code library - the open source libraries would be the ones I would want to see done as an add on to Gideros. For server side, I can probably do that, but if you could I'd prefer to see it done in .NET as this company is a Microsoft based company.

zxing is the open source library that would be a good one to use.

Budget for this is somewhere around $4000. I would get all source code and rights to the end result (except open source stuff, of course) so I can grant them rights.

I think the main problem would be, that Gideros does not expose Camera API to actually get QR image into app.

I think it might be possible by creating a plugin for Gideros to wrap Camera API, but I'm not kind of guy for this work. But the ones that might do that, would be interested in which platforms do you have in mind? IOS, Android or both?

Also if someone wants to create a bar code scanner plugin (for iOS, Android or both), I can always help her/him on this thread or privately.

I'd like to be able to do it the other way; generate a QR code if possible

Generate QR code on mobile's phone screen? Why would you want that?
Well, if there is an internet connection in the mobile, than it's easy using Google Chart API, I've previously wrote some classes in PHP and JS, it would be easy to port them to Gideros.
But I does not really understand the concept behind it. Reader would make sense, but generator? :-/

For those interested, here are a couple of places to start to look at writing an iOS plugin to connect with Gideros.

@atilim, I'd be interested in talking to you about the ways & means of integrating our Obj-C AR recognition code as a Gideros plugin in the months ahead. I've been really enjoying the toolchain of Gideros/Xcode compared to Corona, which I've used on & off for the last 2 years. It's been fantastic to add my own Obj-C customizations straight into Xcode after waiting 18+ months for Ansca to deliver.

@Ianchia, nice to see you here on the Gideros forum. Have heard a lot about you from a lot of Corona users.

Its to redeem coupons on the device, cant say more than that at the moment.

So what kind of data will it store (text, link, contact info) and how data will be input (automatically generated, provided by some sort of service/API, user input)

And is Google Chart API a sufficient solution?

Garyk1968

Yep will return an ID via JSON and a REST API, thanks I'll look at chart api, actually it doesn't *have* to be QR could be the old EAN13C standard.

ar2rsawseen: yes, contact info.

The customers registered at a trade show, and the bar code (qr code) is generated and printed on their badge. Users that have pre-registered just pick up their badge with the bar code on it.

There is no internet connection guaranteed. Some of the trade shows have little to know cell signal.

Full source for Android (Java) barcode library can be found here. I looked into it a long time ago but totally forgot about it.

Actually, the official repository for both iOS & Android (also Actionscript) can be found here.
