Hi Massimiliano,
you have different options.
1. If you have a list like this:
http://my2.raceresult.com/42429/?lang=de#1_108031
you can search in a list with
_Searching
http://my2.raceresult.com/42429/?lang=de#1_108031_183 (Searching everything with 183)
2. What I prefer is to create a certificate with all the results
http://my2.raceresult.com/42429/183/z_Internet_MW
my.raceresult.com/EVENTID/BIB/NAMEOFTHECERTIFICATE
In the designer, you can create a QR code, use the normal barcode and change them to QR.

to create the link fill in "https://my.raceresult.com/EVENTID/"&[Bib]&"/NAMEOFTHECERTIFICATE"
Kind regards,
Felix Schöppe
