Do I have to type in a customer's details every time I scan a ticket?

Generally, you will not have to enter the customer's name, email, and contact number every time you scan a ticket.

Here is how LeadGen helps free up your time (that is better spent engaging with customers to your booth or stall):

If a customer has already registered at their ticket prior to visiting your stand (i.e. during the ticket checkout process, or by scanning with any other vendor that is using LeadGen at your event), then you will not need to re-enter those basic details again, since they will be saved for any vendor that scans the customer ticket using LeadGen.
If a customer has not registered their ticket prior to visiting your stand, then you will be prompted to input the customer's name, email, and contact number. This will only occur when you are the first vendor to scan this customer's ticket at this event. Once saved once, the customer's ticket then updates with their contact information, meaning any other vendors that scan via LeadGen will have instant access to these basic details.
If you have added custom questions to your LeadGen form, then you will always be prompted to input information in those custom questions, every time you scan a customer's ticket. This is because they are your own custom questions. Responses to your own custom questions are never shared with other vendors or the event organizer.

If your LeadGen device goes offline, then it cannot keep syncing data with the EventsPass server. In this instance, you may also be prompted to input the basic customer details, since your app is unable to refresh the data to retrieve any already registered customer information. For this reason, it is strongly recommended that you ensure your LeadGen devices maintain internet connectivity over the course of your event.
