We have been getting good feedback from customers that are checking in thousands of participants for their races. We added the nice custom EMail option with the barcode for each participant.
Today we have made it super fast to scan and go by adding this new option to the Check-In Configuration page on RD Go. When it is checked, after you check someone in, the screen clears and the cursor goes right back to the Registration ID field so you can quickly scan the next person. Scan-Click-Scan-Click-Scan-Click.
