How to solve if Vident scanners shows "The serial number does not exist" error?
Please make sure the serial number and registered password you input are correct.
Please pay special attention to letter “O” and number “0” and letter “I” and number “1” also.
Even though there is a serial number on the back label, please always use the one you found by selecting Setup>About.
Make sure there is no blank space before/between/after the digits you input.
If the registration still fails, please send the product serial number and password, which can be found by booting up the scanner, selecting Setup >About, to www.videntstore.com with a brief explanation of the problem you have. We will check and get back to you with a solution in 2 working day.
