Chip2Go machines will only read barcodes using Code 128 standard, other barcode formats will not be read correctly. 

Barcodes must use a start code with "#" followed by the bib number followed by "~", the bib number will stop being read at the ~ character and any characters after this point will be ignored. If ordering bibs directly from RACE RESULT, ensure to request Chip2Go barcodes to be included. 

You can also use barcodes with numbers ONLY, the whole number will be used as the bib number. 

For example:

301
#301~ 
#301~PARTY
#301~~12345~~

will all return bib number 301. 

 

Using the following will return nothing:

#301
#301PARTY
