How to create an employee QR Code time clock?

If you want to follow the time worked of your employees, one efficient solution is to have them use QR Codes to clock in and out of your company.

Let's first see what QR Codes have to offer as a technology, and then understand how we can exploit it create a time clock for your company.

Why QR Codes?

QR Codes is a technology that boomed in the last few years. It’s fast and practical, everyone has a smartphone these days and can just scan & validate anything. There's a whole history originating from Japan that is worth the read.

If you want, you could even play around and use our free QR Code generator to better understand what can be done with what started from a simple barcode improvement.

We create tools and write about the technologies we use to spread the word about our service. Those tools are free to use forever, so don't hesitate.

The theory

A QR Code could be considered as a simple redirection mechanism, everything that goes after that is up to the device that uses it. In the case of a smartphone, the most common use-case is to process URLs that usually redirect to website or native apps.

To create a time clock system with a QR Code, you must redirect the scan to an API you'd have to build. Then, you need to think of a few essential elements:

• Identify the person. When scanning the QR Code, you'll be redirected to your API, but you must be able to differentiate each client scanning it.
• Register the event. Once the identity is known, you can use a database to store the event itself; the QR Code was scanned by this client at this exact time.
• Compare with past events. If you want to know what was the work duration for this specific person, you must fetch your database and compare the events. A prototype would take the first event as a check-in, and consider the following one to be a check-out and so on. Once those events have this type attached, you can compare their dates and figure out the time worked.

The theory is simple, but building such a system is more complicated than it appears.

Common problems will arise progressively; what kind of database should you use? What kind of dashboard do you want to build? How will it behave with thousands of events at the same time?

The project

If you don't want to bother building everything from scratch Aquiestoy is the tool you need. Once you register for free, you can simply create a new QR Code and let your employees use it. No credit card is needed. It starts for free and if you're a small company, it'll stay free, thanks to our incremental pricing model.

QR Codes are the primary system to clock in to Aquiestoy, but many more are planned to appear such as AI camera recognition, which is the biggest evolution we want to add.

Our smart QR Code technology is based on that. It connects our system to any employee's smartphone easily, and lets them check-in in less than 5 seconds.

Live view

This is one of the first things you’ll notice in the app. From this view, you can see the employee’s check-in and check-out live on your dashboard, so you can keep the page open and let it flow.

Alerting is directly inserted in there and you can use the calendar to navigate between the days.

Timesheet

On top of the detailed insights you can get directly in the application, you can also have a full timesheet list that you’ll be able to export as a PDF or Excel spreadsheet. It’s easy and fast. Feel free to print it whenever you like.

From this timesheet and insight section, you can see the exact time spent at your company and even know all the anomalies that may appear regarding the shift of your employees.

Location

You can choose whether or not you want to know your employee’s location when clocking in, adding more control to the system. This can be useful in case your workers must be physically present in a factory or an office.

There’s an advanced alerting system that will let you know if an anomaly appears.

Settings

The advanced settings are one of the biggest strengths of Aquiestoy. You can customize virtually anything related to the work hours of your employees, the company's open hours, and much more.

If there’s a configuration missing that you’d like to see, don’t hesitate to contact our support and we’ll develop it for you in a matter of days.
