I am evaluating different ChMS to select one suitable for our organization.  With regards to attendance tracking, we use simple barcode scanner(s) as a self check-in attendance recorders.  It records members unique ID scanned from a key tag.  Does RockRMS allow uploading attendance data in bulk (say using a csv file) where a unique ID identifies each invdividual.  We simply want to record attendance of members who are already on our list and have been issued an id, and the stand alone barcode scanners work very efficiently for this purpose. The barcode scanners record the ID and timestamp for each scan.
