It helps to match the time clock to your workflow and team size.

• Punch card time clock: Simple and reliable for basic in/out tracking. Uses physical time cards and an ink ribbon (many include auto-align printing). Great for small teams and locations without network access, but you’ll buy cards and ribbons.
• Biometric time clock: Uses fingerprint, face, or palm recognition to help reduce buddy punching. Many models store hundreds to 1000+ users and offer USB or network data export. Initial user enrollment is required.
• Proximity card/PIN clocks: Fast badge or PIN scans without biometrics. Low-friction for high-traffic entrances.

Consider privacy/consent policies, ongoing supply costs, and whether you prefer offline USB export or a networked setup.

Most employee time clocks support one or more connectivity options. The best fit depends on how you prefer to collect hours.

• USB/offline: Records punches internally; you export data to a USB flash drive (often as CSV/Excel). This approach avoids network setup and many models don’t require monthly fees.
• Wi‑Fi or Ethernet: Useful if you want centralized syncing. Some clocks work offline and sync later when connected.
• Power & placement: Typically plug into a standard outlet; some units include a built-in backup battery. Mount on a wall or place on a stable surface near your entrance.

For biometrics, plan time to enroll users. Checking the product’s specs can help you confirm supported connections and file formats.

Capacity varies by model and technology.

• Punch card clocks: Capacity is more about card management than users. They work well for small to mid-size teams, especially when you organize time cards by department or shift.
• Biometric/PIN/card systems: Many list user databases ranging from a few dozen to several hundred or even 1000+ users. Higher capacities can be helpful if you have multiple shifts or are growing.

Choose a clock with headroom above your current staff count and consider how many punches you’ll record per day. If you anticipate expansion or multiple locations, look for options that allow USB or network exports to streamline payroll processing.

You can find compatible supplies in the Office Supplies section, including dedicated categories for time sheets/time cards and printer ribbons. Many punch card time clocks use specific cards and an ink ribbon cartridge.

• Time cards: Check the clock’s product page for compatible card styles. Buying in bulk can simplify reordering.
• Ink ribbons: Replace when print starts to fade. Look for model compatibility in the description.
• Badges & accessories: If you use proximity or ID card clocks, you can also browse card packs and holders.

Review the “Specs” or “Accessories” section on the product page to match supplies accurately before adding to cart.

Some attendance machines combine time tracking with access features like fingerprint/ID card authentication, a relay for door strikes, or a doorbell function.

• Verify capabilities: Check for a door control relay, supported credentials (fingerprint, card, PIN), and whether it operates offline or over a network.
• Power & hardware: Door locks and buzzers may require separate power and wiring. Confirm voltage and plug type before purchase.
• Installation & safety: For wiring to doors or emergency egress, consider consulting a qualified installer and following local building policies.

If you only need attendance, a standalone time clock can be simpler. If you need both, reviewing the specs for access control features can help you choose a compatible setup.
