General questions

Point of sale (POS) or calculation - the place where transaction occurs. "Transaction" is connected to the POS system or, in other words, to the equipment and software that is used for accounting, the equivalent of an electronic cash register. POS-system manages the sales process thanks to the interface available to the seller.

POS-automation is used as a term describing the automation of sales and discounting processes. Automation of sales in most cases is a system of software and hardware that allows you to manage the processes of registration and accounting. POS automation saves time and money by automating routine manual operations.

Sure. However, the effectiveness of such "unspecialized" POS systems is reduced.

Usually, the business operations of a particular trader are unified. POS-hardware devices, as a rule, can be configured to support specific tasks. Thus, when you program a set of tedious operations at the software and hardware level, you perform sales operations faster and minimize the human factor. As a result, the turnover increases and profit grows.

Using a programmable POS-keyboard together with special software allows you to assign a special function to each individual key, which greatly simplifies the operator's work. POSUA produces keyboards in various designs to help you choose the best option for your POS-system.

What does a traditional POS system do?
A traditional POS system is a complex system consisting of various devices, such as:
  • The central processor (usually based on x86 processors)
  • Power for connecting various peripherals
  • Failproof cash register
  • Cash drawer, cashier display and customer display
  • Various interfaces for connecting programmable keyboards, barcode scanners, magnetic stripe readers and other peripherals.
Depending on the automation program and the workspace, you are choosing a keyboard with more or fewer keys. In keyboards with 84, 96 or 128 keys in addition to the numeric keypad and function keys, you can program shortcut keys for the most used products that are not identified by a barcode, such as baked goods of own production or bakery.
The keyboard with 64 keys is enough for all the necessary functions of controlling the automation program. If the workspace is limited, it is better to use the keyboard with 32 keys.

Our keyboard allows you to create 4 levels of layout and assign a separate key to switch between layouts. You can use various key combinations while programming the keyboard. When choosing a keyboard, it should be borne in mind that it is intended for human use, and therefore the programmed device should be convenient. That is why the choice should be determined by the optimal solution between the expected functionality and the number of keys.


Sure. You can customize your own large buttons of the following format: 1x2, 2x1 and 2x2. If you want to custom buttons with laser engraved inscriptions, please contact our sales department.

If you plan to use magnetic cards in your business, it would be advisable to install a programmable POS-keyboard that already has a built-in magnetic strip reader. This device does not take up much space and serves as it would be 2 separate devices.

The size of the keyboard depends on the number of keys. Keyboards with 32 keys are the smallest, and a keyboard with 128 keys and an integrated card reader is the largest. When choosing the size of the keyboard, you should take into account the expected functionality (the required number of keys). When planning the automation of business, one should keep in mind the convenience of the entire POS-system. The keyboard must correspond to the workplace so that the operator can enter data instantly. The free space for hands is one more thing to think about.

For enterprises operating in adverse conditions (excessive humidity, dust, exposure to corrosive substances, etc.). POSUA manufactures keyboards of the protected type of the LPOS series. Protective membrane protects buttons and electronic components from dirt, damp and other substances that may have a bad effect on the working mechanism.

If you need to restrict access to the POS-system or any confidential data, it would be advisable to install a POS-keyboard with a built-in fingerprint scanner. The fingerprint scanner determines a person with unique biometric functions and blocks unauthorized access to the system. A cheaper way to limit access is to use an electro-mechanical key or Touch Memory electronic key.
