Communications
The SelfCheck system communicates with the library’s circulation system
over the library’s local area network using the 3M™ Standard Interface
Protocol (SIP 1.0 or SIP 2.0) or NCIP, the circulation interface protocol
developed by the National Information Standards Organization.
The system communicates with customers by reading their library IDs and
guiding them through the checkout or check-in process. The SelfCheck
system displays instructions to help the customers solve problems. If these
fail, the system instructs customers to ask for help at the circulation desk.
Barcode formats
The SelfCheck system can identify customers and library items by reading
barcodes. Several barcode formats, or symbologies, are installed on the
SelfCheck system by default:
Codabar
Code 39
Plessey
Telepen Numeric
Code 128
Interleaved 2 of 5
UPC-A 12
If your library uses a barcode format that is not installed, the administrator
can enable it from SelfCheck System Manager.
