Frequently Asked Questions
Q: How do I export attendance data from the N308 time clock?
A: Simply insert a standard USB flash drive into the device's USB port and follow the on-screen menu to download all stored attendance records. The data is saved in a common file format that can be opened in spreadsheet applications like Microsoft Excel — no proprietary software required.
Q: How many employees can this fingerprint time clock support?
A: The N308 supports up to 1,000 registered fingerprints and stores up to 100,000 attendance records. This makes it well-suited for small to medium-sized businesses with frequent daily clock-ins and clock-outs.
Q: Can employees use a card or PIN if their fingerprint isn't recognized?
A: Yes. The 3-in-1 design means employees can authenticate using any of three methods: fingerprint scan, 125 kHz RFID ID card, or a numeric PIN password. This ensures no employee is ever locked out due to scanner conditions.
Q: Does this time clock require an internet connection or monthly subscription?
A: No. The N308 operates completely offline as a standalone unit. There are no subscription fees, no internet connection required, and no cloud dependency — data is exported directly via USB flash drive whenever needed.
