I'd like to put together a mobile-friendly data acquisition app This app would be used in a data center, which means working in a disconnected mode This app also needs to carry (on the client) a mongodb collection of ASCI| character codes, to be matched with the incoming barcodes Once being back online, this app should sync all acquired data with its back-end mongodb
Based on these requirements, I think, meteor would be a good choice
My questions is: are there meteor packages, that can scan an image, and then translate that image to an ASCII character code?

Aspose.Barcode Reader is a free online application to read barcodes from image or your mobile phone's camera. It supports 60+ barcode symbologies including all the popular ones. It is able to locate and read multiple barcodes on image. Our sophisticated algorithm allows you to read even damaged barcodes.
The Scanner class is mainly used to get the user input, and it belongs to the java.
To get barcode scanning capability, use BarcodeScanner cordova plugin:
meteor add cordova:[email protected]
Template
<head>
<title>Barcode Scanner</title>
</head>
<body
{{> barcode_scanner}}
</body>
<template name="barcode_scanner">
<button>Scan</button>
</template>
JS
if (Meteor.isCordova) {
Template.barcode_scanner.events({
'click button': function () {
cordova.plugins.barcodeScanner.scan(
function (result) {
alert("We got a barcode\n" +
"Result: " + result.text + "\n" +
"Format: " + result.format + "\n" +
"Cancelled: " + result.cancelled);
},
function (error) {
alert("Scanning failed: " + error);
}
);
}
});
}
For offline data capability, take a look GroundDB
