Does **QR attendance require extra hardware**? The short answer is no - no terminal, no reader, no cabling. But the longer answer is more useful, because "no hardware" hides a few conditions. This guide sets out the real requirements, the cases where an additional device helps, and an open cost comparison.

## What is required

- **A printed code** - one sheet or plate for each recording point.
- **The employee's phone** - an existing smartphone is enough.
- **An internet connection** - mobile network or Wi-Fi.
- **A computer for the admin panel** - HR already has one.

Nothing on this list has to be bought. The only element that costs anything is printing the code, and that is a symbolic amount.

## What is not required

| In a traditional system | In a QR system |
| --- | --- |
| Terminal or reader | Not required |
| Power and network cabling | Not required |
| Installation work | Not required |
| Employee cards | Not required |
| Spare device | Not required |
| Periodic maintenance | Not required |

Each of these lines creates both an initial and a recurring cost in traditional solutions.

## When an additional device helps

Although hardware is not mandatory, in some scenarios supporting devices add convenience:

1. **A screen or tablet** - to display a dynamic code. Companies that do not want to keep reprinting a code choose this.
2. **A shared device** - a tablet at the entrance for employees without phones.
3. **A durable plate** - instead of paper, for outdoor and dusty conditions.

All three are options rather than requirements. The second is particularly practical - one device can cover dozens of employees without phones.

## A practical example

At an agricultural business most seasonal workers had no smartphone. At first sight the QR solution did not seem to fit.

The situation was resolved like this: a tablet was set up at the entrance to the site and seasonal workers checked in there, while permanent staff used their own phones. One device covered 40 people.

For comparison: the card option required three readers, 120 cards and installation, and collecting the cards back at the end of the season was a separate problem.

## Cost comparison

The difference becomes clearer over a three-year total. In a traditional system the calculation includes devices, installation, cards and their replacement, spare parts, maintenance and additional devices for new points. In a QR system almost all of those lines are zero - only the subscription remains.

## The internet question

The most frequent technical question is what happens at a site without internet. The practical answer: the record is stored on the device and sent once the connection returns, while the timestamp reflects the real moment. A permanent connection at the site is therefore not required - the employee's phone only needs to reach the network at some point during the day.

## Employees without phones

This is the most genuine limitation, and it has three practical solutions:

- A shared device at the entrance.
- A terminal at a critical point - the hybrid model.
- A group record made by a manager - as an exception.

The third option reduces the accuracy of the record and is therefore only recommended as a temporary measure.

## Printing and placing the code

Since the code is the only physical element, a few practical points apply to preparing it.

**Size.** The code should be readable comfortably from one to one and a half metres. A code that is too small forces employees to lean in and creates a queue at shift start.

**Material.** In an office, plain printing is enough. Outdoors, in warehouses and in dusty areas a laminate or plastic plate lasts far longer.

**Position.** At eye level and at a point people must pass. If there are night shifts, lighting must be considered.

**Label.** The name of the point should be written next to the code - "Warehouse entrance", for example. This helps employees confirm they are checking in at the right place.

The cost of all this amounts to a few sheets of paper and some laminate.

## The shared device option

For employees without phones the most practical answer is keeping one shared device at the entrance. This option requires a few details.

The device is installed in a fixed location and connected to the network. Each employee checks in with their own account - the device is shared, the account is not.

In practice one tablet can cover thirty to fifty people; a short queue may form at the start of a shift, but that is no different from the situation with terminal systems.

The cost comparison is clear: there is a significant difference between one tablet and five terminals. Moreover, if the tablet fails it is replaced with an ordinary device - no special model is required.

## The three-year cost calculation

Looking only at the initial cost is misleading. For a practical comparison the three-year total should be calculated.

In the hardware-based option the calculation includes: devices, installation and electrical work, cards and their annual replacement, spare devices, a maintenance contract, additional devices for new points, and the working hours spent restoring records manually on failure days.

In the code-based option almost all of those lines are zero; what remains is the subscription and a symbolic printing cost.

For companies with more than three recording points the difference usually reaches several multiples and becomes the strongest argument for the decision.

## The hidden advantage of the hardware-free model

The absence of hardware is not only a cost question - it also simplifies the organisational side of the project, and that is often overlooked.

In a device-based project the steps are: selecting a supplier, ordering, waiting for delivery, engaging an installer, obtaining permission for electrical work, arranging site access, and testing after installation.

Every link in that chain is a source of delay. In practice most of the rollout time goes not into technical work but into waiting and coordination.

In the hardware-free model almost all of that chain disappears: the preparation consists of writing the rules and assigning the schedules - both internal tasks that depend on no external party.

As a result the project takes days rather than weeks, and the risk of delay drops to a minimum.

## In summary

QR attendance requires no additional hardware: existing smartphones and a printed code are enough. This cuts both the cost and the rollout time sharply.

Two cases are exceptions - staff without phones and areas where phones are prohibited. Both are solved with a shared device or a hybrid model, which is still far cheaper than a fully hardware-based setup.

When deciding, the comparison should be made on the three-year total cost rather than on initial prices - that is where the difference shows.

## The next step

The simplest way to clarify the hardware requirement is to ask one question: what share of the team has a smartphone? If the answer is above 90%, additional devices will almost certainly not be needed.

## FAQ

### What is actually required?

A printed code for each point, the employee's existing smartphone, a network connection at some point during the day, and a computer for the admin panel - which HR already has. Nothing on that list needs to be purchased.

### What about employees without smartphones?

The practical solution is a single shared device at the entrance, where each person checks in with their own account. One tablet typically covers thirty to fifty people - a very different cost from installing several terminals.

### How should the code itself be prepared?

Large enough to scan from one to one and a half metres, laminated for outdoor or dusty areas, placed at eye level in a spot people must pass, with the point name printed next to it so employees know they are at the right place.

### How does the cost compare with a turnstile or fingerprint terminal?

The real difference is not the initial price but the recurring one: opening a new point, replacing a device, consumables and maintenance. In a device-based model every new site becomes its own project; with codes the cost of adding one is practically zero. Compare over a three-year horizon.

### Does having no hardware make it less reliable?

The opposite: the single point of failure disappears. A printed code cannot break, needs no power, and can be reprinted in minutes if damaged. The thing that does need attention is different - recording discipline has to be supported organisationally.
