You can import a CSV file with attendance data that is exported from the biometric device(as long as it can match the sample template). The administrator will be able to upload this in OrangeHRM.
OrangeHRM also can provide an FTP location for you to share the CSV export from the device. OrangeHRM then can process the file to match the system required template and automatically upload it to the system.
Please find the article on how to directly import attendance data from biometric devices into OrangeHRM.
