The Format tab view provides settings for card types: ISO, AAMVA, USER, & RAW.
Data Density
: The data is encoded on the magnetic stripe as a string of binary bits. The
physical length of each bit on the stripe is the data density specified in Bits per Inch (BPI).
There are two data densities for magnetic stripe cards: 210 BPI or 75 BPI.
Leading Zeros
: This is the number of zero value binary bits preceding the Start Sentinel (SS).
These zeros are used for synchronizing the reading circuits and bit-decoding
algorithm. These zeros are required. The number of zeros required is based on the data
density and the ISO required distance of the SS from the edge of the card.
High Coercivity
: This is a check box in the Format window. The EzWriter writes on HICo or
Lo-Co magnetic stripes. This box selects the coercivity the EzWriter is to use. The default is
Lo-Co. If the card coercivity is not known, use Lo-Co first and if there is a
consistent write error, then switch to the Hi-Co setting.
The User Type tab view provides settings that apply only to the card type USER.
Start Sentinel Characters
: This character marks the beginning of the track data field. This
character is preceded by leading zero bits.
End Sentinel Characters
: This character marks the end of the track data field. There is a
Longitudinal Redundancy Check character (LRC) following the end sentinel. The LRC is
used for error checking the data bits. The LRC is calculated by WorkShop and added
automatically when writing to a card. There are trailing zeros following the LRC.
Bits per Character
: The bits per character can be selected from 4 BPC to 7 BPC. The
standards are 5 BPC for numeric characters including the parity bit or 7 BPC for
alphanumeric characters including the parity bit. See Appendix B for the character tables.
Parity
: The character parity bit logic can be selected. The default and standard selection
for 5 and 7 bit characters is “Odd” parity. The parity bit for each character is added by
WorkShop as the character is written on the card. For 4 or 6 BPC characters, parity must
be “None”.
Write
This function writes data to the magnetic stripe when the card is swiped through the slot.
WorkShop writes the data in the track text boxes together with standard or user defined
SS, ES, and LRC each time a card is swiped through the slot. A prompt window opens to
inform the user to swipe a card for writing. The Message box at the top of the WorkShop
window shows the result for each card swipe, either the card was written OK or an
ERROR was the result. The Message box also gives the count of the cards that have
been swiped and written with no errors. For sequentially changing numbers, see
Sequential Write below. To finish the Write process, click on the End button to close the
prompt window.
