We are using Zxing API for generating string to upc-a barcode image. But that image contains only barcode, but not with string like as the image in below link:

So please suggest us how to generate barcode image with both barcode and string Sean Owen
UPC-A barcodes are designed for scanning products at a shop's checkout. They encode a world-wide unique 12 digit number for the product (13 digits for EAN-13 or GTIN-13, which is compatible with UPC-A). Product numbers are assigned by the international organization GS1.
Therefore, UPC-A barcode should not be used for anything else than to encode GS1 product numbers. And they are technically unable to encode strings.

I have written a simple barcode app using VNBarcodeObservation in iOS... it works perfectly fine on 12 and 13 digit UPCs. However, when I scan an older Star Wars toy with 11 digits in the UPC, it adds a 12th digit to the UPC. For example, the code "07628169570" is interpreted as "076281695709" (the 9 at the end is added). The website barcode.tex-it.com does the same thing if I say the 11 digit code is UPCA (see link - https://barcode.tec-it.com/en/UPCA?data=07628169570) - it appears it's trying to force an 11 digit barcode to act as a 12 digit UPCA, which is not what I want... I want it to read the 11 digits... Is there anything I can do to force VNBarcodeObservation to just look at the 11 digits? Simply dropping the last character isn't an option, because I need the app to also read 12 digit barcodes. I feel like I should be able to have the app use a different symbology on an 11 digit code, but I'm not sure how. Thanks.
There is no 11-digit UPC-A.
The specifications of UPC-A are 12 digits, and 13 digits are compatible with EAN.

The web service site you used was entered with 11 digits of data as UPC-A, so it probably complemented the check digit and displayed the correct UPC-A barcode.
For example, the barcode printing function of a receipt printer has such a complementary process.
If the 11-digit number is printed with the barcode attached(There are called Human Readable Interpretation characters), it probably omits the check digit.
It is conceivable that we have a unique operation that makes a difference in order to distinguish between the case where the barcode is read by the scanner device and the case where it is input by a human.
Wouldn't the application automatically calculate the check digit if entered by a human?
Or maybe you change the setting so that the notification from the scanner device is only 11 digits with the check digit removed.
If you have a product with an 11-digit HRI bar code, find out why it's 11-digit.
There may be some specifications that you have to consider.
I have created one bar code scanner application and used AVFoundation native framework. Some of our barcode contains hidden unicode characters and we are unable to scan it. Here is an example of bar code:
]d201000000000010!0000-023
I am getting above code like: \u{1D}01000000000010\u{1D}0000-023
In above barcode ]d2 varies. I am unable to find type of the barcode. How can I parse that Unicode contained string into normal string? Does any one face this type of issue or barcode? Thanks in advance.
\u{1D}01000000000010\u{1D}0000-023 Looks to be a GS1-formatted barcode. Full spec is here And the values after the {1D} delimiter are call "application identifiers" and identify the type of data contained in that field. GS1 is really common in any industry where full supply-chain tracking is needed such as the medical device industry, etc. A concise list of application identifiers is here

Is this question related to finnish banking barcode ?
if YES: You must pad the data to be of even length, according to the documentation published by the bank. Switching the barcode encoding system is not allowed by the relevant banking standard.
reference URL: http://www.finanssiala.fi/maksujenvalitys/dokumentit/Bank_bar_code_guide.pdf
if NO: Just first encode the even-length part, then switch to code 128A or 128B using the encoding switching special "character" and finally encode the last digit using either 128A or 128B, whichever serves you better.
We need to parse the GS1 datamatrix barcode which will be provided by other party. We know they are going to use GTIN(01), lot number(10), Expiration date(17), serial number (21). The problems is that barcode reader output a string, the format is like this 01076123456789001710050310AC3453G321455777. Since there is not separator and both serial number and lot number are variable length according to GS1 standard, we have trouble to identify segments. My understanding is that it seems like the best way to parse is to embed the parser in the scanning device, not from the application. But we didn't plan an embed software yet. How can I implement the parser? Any suggestions?
There should be a FNC1 character at the end of a variable-length field that is not filled to maximum; so that FNC1 will appear between the G3 and the 21.
FNC1 is invisible to humans but can be detected by scanners and will be reproduced in the string reported by the scanner. Simply send the string directly to a text file and examine the text with a hex reader. the FNC1 should be obvious.
If you can, it might be an idea to swap the sequence of the 21 field and the 10 field since you appear to be using a pure-numeric for 21. This would make the barcode produced a little shorter.
One way to deal with this is to program the scanner to replace FNC1 with space or another plain text character before sending it to your application. The scanner manufacturer usually provides a tool to produce programming bar codes that can do simple substitutions in the scanner. Then you can parse the data without having to handle special characters.
I'm reading barcodes in an iOS app using the built-in barcode recognizer.
I scanned the barcode on a bottle of prescription medication. I'm expecting this barcode to resolve to a number that I can use to refer to a medication database. What iOS tells me is this:
type: org.iso.Code128
string value: xAAAJ5wEA
I checked the Wikipedia entry for "Code 128" but I'm still not sure how to decode the string further. I'm assuming it's a "Code Set C" value, but I don't see how to translate it into the series of decimal numbers I'm expecting.
Any help would be appreciated, thanks.
Code 128 is a compact one-dimensional barcode primarily used for alphanumeric barcodes. All 128 characters in ASCII are encoded.
In this case, your result is almost certainly a barcode encoding "xAAAJ5wEA". That barcode looks like this Code 128 barcode:
Prescription medication tend to encode a great deal of information. Possibly the customer record number, how many refills, what medication, etc. It can be used to pull up all information about the customer in the pharmacy computers. Precisely how this data is encoded will likely be based on the pharmacy policies. Therefore you will need to customize your software for each pharmacy.
