Interesting (but not surprising) to note is that, in the encoded string, there is a unique identifier. Observe the following, performed on the same machine (mine) with the same barcode (Hill Country Fare Strawberry Toaster Pastries) using two different :CueCat scanners.

1:
3nZC3nZC3nXC3j1D3r3CNnY.fHmc.C3DYCxfZCxr7Dxf1.

2:
3nZC3nZC3nXDhz0DhP3CxnX.fHmc.C3DYCxfZCxr7Dxf1.

Note that the two scans differ only in the first block (period-delimited).

Just goes to show how The Man keeps you under his thumb...
