Are there hand scanners which buffer scanned data for later upload to EE?

We have tested a couple scanners but they appear to need a bluetooth or physical connection to update the database upon scan.

Is there scanner technology that would store the scans on a card or thumbdrive for later update in the event of an internet outage? Would you have any recommendations?

Hi there,

In short, you’ll need something custom for that approach.

The way the scanners work is you scan a QR code, and the app/barcode scanner add-on requests the details for that registration from the site using the code in the barcode as an identifier. Meaning they are not just updating the database, they read all of the information from the database first, then when you check in, update. The only information in the barcode itself is an ID, which means if all you scan is the barcode then you can’t validate the registration at the time of scanning.

I don’t know of any handheld barcode scanners that will save the scans to a file within the scanner itself, but most barcode scanners act as a ‘keyboard wedge’ meaning they are pretty much seen as a keyboard by the device they are connected to. The scanner scans the code, deciphers it and sends it to the device in the same way a keyboard would (I’m simplifying this). This means that you ‘could’ use something like excel or a text file, set that file in focus and scan with the scanner to send the ID’s over to that file without doing the processing the apps/barcode scanner add-on does.

I’m not sure if thats what you are looking for as you still need the ‘device’ connected to the scanner to store the details, but it’s the closest I can think of.

One other option is to use a barcode scanning app like this –
(I used this app as a workaround to scan barcodes before the mobiles apps existed and it worked well with the barcode scanner add-on, same idea just without the add-on)

And then on the mobile device do something very similar to the above, have a text file/memo file open and scan the barcodes to the file. Again you’lll have no processing of scans when doing this but you will have the ID from the barcode.

Finally, you may find it better to just print the registration report for the event so that if all else fails, you have a hard copy you can use as people arrive.
