We are looking for a way to keep track of people who enter our building and we would like to keep track of the person as well as what time they entered the building and what time they left the building, utilizing Marketo. We were thinking of a Marketo LP and having the form update based off date/time entered, but is there a better way to do this or a launchpoint partner that would be able to? My biggest concern is that we want to keep track of every time the person is in the building so we can look back at is as a log record, but I am not sure how to make sure the field does not over-write every time and stores all values for every time they enter. Does anyone have any ideas? thank you!
