Quantum Blue Technology LLC develops high quality computer software and documentation for IBM Personal Computer and Embedded Microprocessor Applications. Our Point Of Sale Business Application utilizes proprietary fault-tolerant, distributed database technology which permits normal POS Client Terminal Sales operation even during conditions when the POS Server and/or the Network hardware has failed - most other POS systems would be unusable during these times, requiring the counter staff to create hand written sales based on possibly outdated price catalogs - such hand written sales are sources of error and also have to be manually entered when the POS Server and/or the Network hardware has been repaired.
