PaperCut – Ricoh Embedded Manual



A typical case is the checksum being reported after the card number, separated by

an equals sign, such as in 5235092385=8. PaperCut can handle this case by

default; it will extract the number before the equal sign as the card number:

5235092385.



For some cases, a "regular expression" may be required that will filter the card

number from the complete string of characters reported by the card reader.

Documentation on regular expressions can be found on the Internet, e.g. at

www.regular-expressions.info.

o The regular expression must be fashioned so that the card number is

returned as the first match group.

o Usually one regular expression will be used for all the devices managed by

PaperCut; this must be entered in the "Config editor" in the PaperCut Admin

Console. Open the Admin Console and select the Options tab, then select

"Config Editor (Advanced)" from the left menu. The key is called "ext-

device.card-no-regex".

o The global setting however can be overridden on a per-device basis: The key

"ext-device.card-no-regex" can also be found on the "Advanced Config" tab in

the device details screen. This setting will override the global setting unless

the keyword "GLOBAL" is specified.

o PaperCut developers will gladly assist in producing a regular expression

when supplied with a few sample outputs from your card reader. Please

contact PaperCut support.

o If you would like to write your own regular expressions, here are some

examples:



Revision: 19

Use the first 10 characters (any character): (.{10})

Use the first 19 digits: (\d{19})

Extract the digits from between the two "=" characters in

"123453=292929=1221": \d*=(\d*)=\d*
