Reviewed in Canada on April 11, 2025Récemment, j’ai testé l’horloge pour petites entreprises, horloges WiFi 2,4 GHz avec empreintes digitales avec batterie de secours de la compagnie NGTeco. Le produit est fait de matériaux de bonne qualité: un plastique qui semble assez résistant.
On peut le connecter à un réseau informatique grâce à un câble réseau RJ-45 ou par Wi-Fi 2.4 Ghz. Il peut également être synchronisé avec une application disponible sur Android ou iOS. On peut alimenter l’appareil gaĉe à l’adaptateur électrique fournis avec le produit ou par un câble d’alimentation à 2 pin (non inclus) 12V que l’on branche dans le port derrière l’appareil. L’appareil est également muni d’une batterie de secours lorsqu’il manque d’électricité.
Notez par contre que l’interface usager est seulement en anglais J’ai essayé de trouver s’il y avait moyen de changer la langue, mais sans succès.
C’est un outil très utile pour les petites entreprises et ainsi permettre de faciliter la gestion de vos employés. On peut gérer jusqu’à 3000 usagés et 200 000 enregistrements. Il intègre un scanner d’empreinte digitale qui fonctionne plutôt bien. Il est relativement simple d’utilisation et on peut télécharger les rapports d’utilisation sur une clé USB, par le réseau ou avec l’application. C’est un produit d’une bonne qualité et je vous le recommande.

- Reviewed in Canada on April 16, 2025The time clock can be used completely independently, the cards can be easily purchased, the function is good and actually sufficient. The configuration is well described and easy to carry out. Even if the T9 text input is a little awkward, the device can be set up quickly. The export via USB stick is also fine. This way you don't introduce a security vulnerability into your company network with a potentially insecure device. However, I find the price borderline, hence the point deduction.
- Reviewed in Canada on May 16, 2025The old punch card time clock at work finally died, so I replaced it with this one.
I like that we can use cards or a simple thumbprint to have our employees log in or out each day. There's no monthly fees, which I love, and the Android app ensures I can keep track of all employee breaks from anywhere in the building.
It was simple to program, as everything can be done on the app except logging of fingerprints, and if you have issues the manual is fantastic. So far, we've had no issues, and quite honestly, I believe our staff are being paid correctly because no one's complained about missing hours at all.
It's saved us time and money, so I absolutely recommend this to others

- Reviewed in Canada on April 19, 2025The unit proves to be a practical and user-friendly solution for small business time tracking. Setup is relatively straightforward, whether you're using the device itself or pairing it with a mobile app. Fingerprint recognition works quickly and with high accuracy, and the automatic clock-in/out function removes the need for manual input, which streamlines daily operations.
The system can be used independently without connecting to your company’s network, adding a layer of security, and the USB export option is a nice touch for data management. Built-in Wi-Fi and app compatibility allow for real-time monitoring, helping business owners keep an eye on attendance patterns. It even retains data during power outages, which adds to its reliability. While some might find the price on the higher side and the lack of detailed app instructions a minor drawback, the overall performance makes it a solid investment for efficient employee time tracking.
- Reviewed in Canada on April 2, 2025This allows you to take note of lazy or competent employees. It has wifi built-in and also can be synced to an Android or iOS app allowing you to monitor your employees at work to see if anyone is leaving extra early or leaving after working overtime.
- Reviewed in Canada on April 9, 2025I just set this up today, and it's already making time tracking way easier. The fingerprint recognition is quick and accurate, and I love that it automatically knows if someone is clocking in or out—no more guessing or pressing buttons.
The app setup was pretty straightforward with my phone, and I like that it's all paperless. It even stores data during power outages, which gives me peace of mind. So far, it seems like a solid and reliable upgrade for our small business.

5.0 out of 5 starsEasy to use time clock for small places. It is a great option for small businesses like mine that want an easy way to track employee hours. The scanner works well, and the auto punch-in feature makes clocking in and out so easy. The built-in battery backup is a nice touch in case of power outages, and there are no monthly fees, I don't have to worry about subscriptions. Setup is easy with the app, and reports can be downloaded straight to your phone. It's a good, reliable, paperless time-tracking system.Easy to use time clock for small places
