Barcode for validating sets
The OCR-A and OCR-B character sets contain both upper and lower case letters, numbers, and several special characters.
The OCR-A font characters were created from ANSI X3.17-1981 specifications and the OCR-B font characters were created from ANSI X3.49-1982 specifications.
and we need to make sure that when barcode is provided both job and sample numbers are not provided.
The low-level checks need to make sure that individual values have the correct state and on top of those we can define our high-level rule: rule which says “barcode can be filled only if both job_number and sample_number are empty”.
It can encode GS1 data, letters, numbers, text and actual data bytes.Similar to rules that depend on results from other rules, you can define high-level rules that need to apply additional predicates to values provided by other rules.If you want to be reassured about the quality of your printed barcodes, but do not have an ISO/IEC-compliant verifier, then we are happy to do this verification for you.It will more easily facilitate companies to win the consumers’ heart, boost brand value and consumer confidence.By Scanning GS1 HK Barcode through We Chat ‘Sweep’ Function The number of monthly active users on We Chat has reached 800 million on average as of August 2016, significantly outnumbering other social platforms.
