Barcode scanner use

I have tested the QR code portion of the Events system and it works great, but Id like to know if I can use a proper bar code scanner to achieve the same, assuming thre bar code scanner has the facility to talk with the website?  Has anyone done this at all?

I have installed MPDF as that supports printing of a BARCODE .and a similar question for membership Cards 
I saw some example code
<tr>
<td align="center">UPCAP5</td>
<td>UPC-A barcode with 5-digit EAN-5 supplement. This is a subset of the EAN-13</td>
<td class="barcodecell"><barcode code="07567816412 90000" type="UPCAP5" class="barcode" /></td>
</tr>
right when I look at the code for Membership Card I see similar code
<tr>
<td style="width: 50%;" align="left">Address:</td>
<td align="left">[ADDRESS], [CITY], [STATE], [COUNTRY]</td>
</tr>
which works of course
so can you try with your test system loaded with MPDF and see if you can get it to work to print a barcode using the substitution of [MEMBERSHIP_ID]
I used an online barcode generator to show what we want to see and attached the file 

Hello

You can try to test it yourself please. Just replace the hardcoded string 07567816412 90000 with the tag [MEMBERSHIP_ID] to see if it works
