Barcode UID is a module that displays the user ID of the currently logged-in user as a Code 128 barcode[1].
Module settings
| Parameter | Value |
|---|---|
| Display barcode text | (Yes | No) Display the text value of the logged-in user’s account overlaid over the barcode. |
| Display username text | (Yes | No) Display the username of the logged-in user’s account beneath the barcode linked to the user profile. |
The module can be assigned to any available module position. If the person viewing the page has not logged in then a link to the login module will be displayed instead of the barcode.
Notes:
[1] The barcode is generated by PHP using a technique developed by Casper Bakker.
