Sub-group PC-B: Franks from Neopost software, ID numbers with 04#N or NO4#N prefix[edit | edit source]
The stamp designs are quite different from each other. One has a four-pointed star logo, two have a torch in hand logo, and one has no logo. Even the bar codes are dissimilar.
Neopost was the second company to enter the PC postage business with an experimental design sometime in early 1998. Circumstances of the trial remain unknown to us.
Stamps are found both with and without FIM barcode at top left. Examples are not known with slogan or slug.

Between the bars at right are a torch-in-hand logo left of small "U.S. POSTAGE" reading up. Also between the ars are the class of mail, the value figures (centered), and the date.
