Improve Barcode Scanning Accuracy and Utility
Regular Expressions, commonly known as “regex”, are pivotal in enhancing the accuracy and efficiency of barcode scanning processes. By integrating regex, businesses can significantly reduce errors and boost productivity. The CodeREADr app, compatible with iOS and Android devices, has facilitated regex usage for an extended period, streamlining data capture and identification tasks.
Introducing ChatGPT: Your Regex Writing Assistant
ChatGPT revolutionizes the way regex codes are created. By simply describing the desired pattern and outcome to ChatGPT, users can obtain a functional regex code within seconds. For verification and testing of the code, resources like the Regex101 website are available, ensuring the code’s efficacy before implementation.
This advancement empowers even those with no development background to integrate regex into their systems, thereby enhancing data capture accuracy and saving valuable time and resources.
Key Applications of Regex in Barcode Scanning
Regex can be strategically used in several areas within the CodeREADr barcode scanning software to improve utility and accuracy:
- Alter Scanned Values. Here regex is used to change the scanned value to match the required result in a database.
- Alter Responses to Scanned Values. Here regex is used to display a specific response to an app user when a certain pattern is detected.
- Export Templates to Normalize Data. Here regex is used to change the format of the scanned data to match the format required in the target database.
- Custom On-Device Validation (COV). Here regex is used to stop app users from scanning barcodes that don’t match specific patterns. COV is a sophisticated, edge computing technology based on no-code/low-code implementations on the scanning device itself.
Optimizing Queries for ChatGPT
To achieve the best results with ChatGPT, specificity in your queries is crucial. For instance, when integrating with CodeREADr, your query might look like this:
“Please provide a regex pattern and substitution input using an online regex tester like regex101.com to display the values from a UPC barcode with the leading zero and check digit removed.”
Following this detailed query format ensures that the responses received are accurate and applicable, as demonstrated in our guide on removing the leading zero and check digit from a UPC barcode.
Inventory Audits and Cycle Counts
Example: Remove the Leading Zero and Check-Digit from UPC Barcode
Scanned UPC Value: 012345678901
Regex from ChatGPT
Pattern: ^0(\d{10})\d$
Replacement: $1
Regex101: https://regex101.com/r/rbcdLi/1
Result: The value “1234567890” will now accurately match the value in the inventory database.
Logistics
Example: Serial Number Extraction from GS1 Code-128
Scanned Value with serial number 12345678: (01)05410013111009(10)ABC123(21)12345678
Scanning Result
GTIN = (01)05410013111009
BATCH/LOT = (10)ABC123
SERIAL = (21)12345678
Regex from ChatGPT
Pattern: (?s).*\(21\)(\d+).*
Replacement: $1
Regex101: https://regex101.com/r/HjpEOL/1
Result: The serial number “12345678” can now be used to track where items have been shipped and deployed.
Medicine and Medical Equipment
Example: Lot Number Extraction from GS1 Code-128
Scanned Value with lot number 10003456789: (01)00314141999995(10)10003456789(21)20006500234
Scanning Result
GTIN = (01)00314141999995
BATCH/LOT = (10)10003456789
SERIAL = (21)20006500234
Regex from ChatGPT
Pattern: (?s).*\(10\)(\d+).*
Replacement: $1
Regex101: https://regex101.com/r/m93R0i/1
Result: The lot number “10003456789” can now be used to verify if it’s a recalled item.
