BARCODER - Create 1D and 2D Barcodes (QRCode , C39,etc)

[serzh82saratov]

Hello! Is there a version with Unicode support?
Or tell me how to fix it.
From the message just me I did not understand how to do it.

[serzh82saratov]

As I understand it, you need to change only CONVERT_TO_BYTE_ENCODING?

Great script!

The following function enable scripts to support Kanji (Japanese/Korean/Chinese Characters) encoding

Code: Select all

Kanji_encode(str)
{
    tmp := StrSplit(str)
    for k,v in tmp
    {
        c := Asc(v)
        If ((c >= 0x0001) && (c <= 0x007F))
            out .= v
        Else if (c > 0x07FF)
        {
            out .= Chr(0xE0 | ((c >> 12) & 0x0F))
            out .= Chr(0x80 | ((c >> 6) & 0x3F))
            out .= Chr(0x80 | ((c >> 0) & 0x3F))
        }
        Else
        {
            out .= Chr(0xC0 | ((c >> 6) & 0x1F))
            out .= Chr(0x80 | ((c >> 0) & 0x3F))
        }
    }
    Return out
}

This is a test example

Thanks for the feedback Zhang, and thank you for your contribution on Kanji. I will add a reference to your post in the OP

[Epialis]

i Know this is an old topic, but how would you use this to store a username and password to login a system? Thank you. I mean like, how dr's just show their card to the computer and it logs them in?

Don't worry, no rules against "necro-posting" here
I think you can use the text/string of the QRcode and use it as the encryption key. Or have the QRcode structured with something like username:password but it would be risky for security since someone who takes a picture of the card... You could enrypt using something like a key-pairs like PGP, but still...

I defer to others here

Joe pretty much nailed it.

I have seen the following routine though: Supermarket cashier has to log in using a password (not in the card) early on in the day and then (after this primary login) he/she uses a QRCode Card for "secondary logins" to ensure that he/she "is in that station" whenever a new customer arrives at the cashier. Might this be what you have seen?

Main concern is that regular QR Codes are quite easy to copy. Just take a picture of it with a smartphone and then you can activate a scanner from the smartphones screen (displaying the picture). For this reason, a login routine fully based on a Card with a QR Code would probably be restricted to very specific situations (i.e. user has no access to any data, but merely inputs into a form and the login routine is merely to know who created that register).

That being said, magnetic cards are not totally copy-proof either and UV QR Codes (printed using invisible UV paint and then scanneed only with a UV scanners) might take the security up a bit. Quite sure these have been used in night clubs to track paying customers (all-inclusive, etc. QR Codes are painted onto their skin using UV paint).

Proper consideration of security needs in the routine is a must in ANY case.
