Only applies to continuous mode. The period, in milliseconds, before the same QR code

Well, I do not sleep for several days. I tested several Qr readers and the only one I found interesting was this one, to perform a quick reading, it is necessary to decrease "delay", the same Qr is repeated several times.

The solution I found for not to repeat for a certain time:

bundle.js > add rows the top:

var arrayResult = [];
var timeoutResult;

function removeA(arr) {
    var what, a = arguments, L = a.length, ax;
    while (L > 1 && arr.length) {
        what = a[--L];
        while ((ax= arr.indexOf(what)) !== -1) {
            arr.splice(ax, 1);
        }
    }
    return arr;
}

function timeout(arrayResult, result) {
	timeoutResult = window.setTimeout(function(){ 
		removeA(arrayResult, result);
	}, 5000);
}

function clearResultTimeout() {
    clearTimeout(timeoutResult);
}

function insereValor(result) {
	
	if (arrayResult.indexOf(result) < 0){

		clearResultTimeout(); // delete timeout from (result) previous
		arrayResult.shift(); // remove lock (result) previous
		arrayResult.push(result); // add lock (result) current

		this.setState({ result: result }); // result
		
		timeout(arrayResult, result);  // setTimeout

	}else{
		//alert(result); // lockout timeout
	}
}

bundle.js > search by for lines:

	    value: function handleScan(result) {
			if (result) {
				this.setState({ result: result });
			}
	    }

bundle.js > change to:

	    value: function handleScan(result) {
			if (result) {
				insereValor(result);
			}
	    }

Is the reading happens faster and if the QR is repeated, it is discarded for 5 seconds.

Yes the scanner will give the result of every scan. Even if that might be the same as the previous result.
