starfish's explanation of how to decrypt the barcode was not very clear, so i will elaborate on it.
here is an example barcode that i scanned:
.C3nZC3nZC3nYCxfZE3b0CxnX.fHmc.C3T0ENz7DNTZDNf2.
the periods mark the different parts of the encrypted barcode:
group 1 = C3nZC3nZC3nYCxfZE3b0CxnX
group 2 = fHmc
group 3 = C3T0ENz7DNTZDNf2
group 1 is the serial number of the cuecat scanner (i reformated it for easy decoding):
C3 n Z C3 n Z C3 n Y Cx f Z E3 b 0 Cx n X
use this chart to decode it:
1 2 3
0 C3 n Z
1 CN j Y
2 Cx f X
3 Ch b W
4 D3 D 3
5 DN z 2
6 Dx v 1
7 Dh r 0
8 E3 T 7
9 EN P 6
so this: C3 n Z C3 n Z C3 n Y Cx f Z E3 b 0 Cx n X
is this: 0 0 0 0 0 0 0 0 1 2 2 3 8 3 7 2 0 2 reformated for easy reading as serial number: 000000001223837202
group 2 is the barcode type
use this chart:

CC! aabi CueCat:

so fHmc is barcode type UPA (what ever the hell that is)
group 3 is the actual barcode (reformatted):
C3 T 0 EN z 7 DN T Z DN f 2
use this chart to decode it:
1 2 3
0 C3 n Z
1 CN j Y
2 Cx f X
3 Ch b W
4 D3 D 3
5 DN z 2
6 Dx v 1
7 Dh r 0
8 E3 T 7
9 EN P 6
so this: C3 T 0 EN z 7 DN T Z DN f 2
is this: 0 8 7 9 5 8 5 8 0 5 2 5 reformatted as 0 87958 58052 5
hope this helps. i what to write a little windows program that will do the decryption for you.
