  Hi! I am an independent Kronos Consultant. Kronos timeclocks / terminals are capable of reading ANY barcode format per their configuration (default is ALL formats), however barcode placement on the timecard is usually the critical factor. Here is a short version of the badge spec. If you need more info, please contact me with your email address. Good Luck!

  Badge Design Specifications

  Description
  When creating badges for the Timekeeper Terminal, there are strict requirements with regard to the badge, the bar code format, and the location of the bar code on the badge.

  The bar code reader built into the terminal can read many bar code formats; by default it is programmed to read Code 39 or 3 of 9, Interleaved 2 of 5, and Codabar. It is a medium density device, and can read bar codes that are between 6 and 15 mils (a mil is a thousandth of an inch, so that translates to between 12 characters per inch and 5 characters per inch). Kronos standard badges use 8 mil, 8.5 character-per-inch, bar code.

  There must be ‘quiet zones’ before the start of the bar code and after the end; they should be at least 10 times wider than the narrow element in a bar code. Therefore, for 8 mil code, the quiet zone should be 80 mils wide, just under one tenth of an inch.

  The bar code should be centered about .45 inches from the edge of the badge, and should be at least .5 inches wide. It must be parallel with the edge of the badge; the angle between the edge of the badge and the edge of the bar code should not exceed 2 degrees.

  The wide elements of the bar code should be about 2.5 times as wide as the narrow elements.

  The terminal’s reader is infrared, so it should be printed with high-carbon ink or toner which shows infrared well.

  The Code 39 symbology format is as follows:

  • Employee ID Number 10 characters zero plus 9 digit badge number

  • Company Code 4 characters static value of ’3232′

  • Restriction Level 1 character static value of ’0′

  • Reserved Digits 2 characters static value of ’00′

  The Interleaved 2 of 5 symbology format is as follows:

  • Employee ID Number 11 characters two zero’s plus 9 digit badge number

  • Company Code 4 characters static value of ’3232′

  • Restriction Level 1 character static value of ’0′

  • Reserved Digits 2 characters static value of ’00′

  Restriction level can be changed if you need to limit specific employees from a specific timekeeper terminal. This requires the clock to be programmed to accept a specific restriction level. When the value is set to ’0′ there is no restriction on who can use this timekeeper terminal. Reserved Digits is always ’00′.

  Do the TimeKeeeper clocks (specifically the 4500′s) use a pass-through type bar code reader or does it use a reflective type? We use the badges with pre-printed bar codes and a lot of them wear off from use. So, can I use a sticker printed with the same bar code to place over the old worn one? Or if it uses a light passed through will the one below interfere with the reading of it? I have done this with some success, but sometimes it doesn’t work really well, which caused me to suspect that too much of the old bar codes remained on some of the cards… Any thoughts?
