<META HTTP-Equiv="scanner" Content="allDecoders:disabled">
<META HTTP-Equiv="scanner" Content="Code128:enabled">
<META HTTP-Equiv="scanner" Content="enabled">

Above example can also be written as shown below:

<META HTTP-Equiv="scanner" Content="allDecoders:disabled;Code128:enabled;enabled">

or

<META HTTP-Equiv="scanner-all_decoders" Content="disabled">
<META HTTP-Equiv="scanner-Code128" Content="enabled">
<META HTTP-Equiv="scanner-enabled" Content="SCN1">

The following example enables the scanner to read all labels except Code128:

<META HTTP-Equiv="scanner" Content="allDecoders:enabled">
<META HTTP-Equiv="scanner" Content="Code128:disabled">
<META HTTP-Equiv="scanner" Content="enabled">
