RJL Systems needs donations for Interactive Online BIA

For most of the last 20 years, RJL Systems has provided the Online Interactive BIA service, which allowed anyone with an internet connection to generate a one-page body composition report, regardless of whether they have access to a computer with our desktop software installed. Until now, this service has been offered for free and with no restrictions.
