What are cash registers and what are their benefits?

Cash registers are devices used to calculate financial transactions. Most cash registers consist of a keyboard that is used to enter entries, a drawer to store cash, and a printing device for receipts. Some models also incorporate a scanner of some kind.

Today, cash registers can perform a wide variety of additional functions, such as credit card processing, personal check verification and inventory control. There are 2 models of cash registers: mechanical cash registers and digital cash registers.

While there is a wide variety of makes and models on the market, the price of cash registers will vary according to their specifications.

  • They are usually very expensive to buy and maintain
  • Employees are required to have a minimum of training before using them

How do cash registers work?

The first ones consisted of different cards made of a rigid material that were punched for each sale made, while digital cash registers work in a similar way to a computer and, unlike the mechanical one, they print a receipt or ticket.

Cash Register or Point of Sale Terminal What should you pay attention to?

Today it is very common that next to the cash register of an establishment, shop, supermarket or store there is another small device. This device is the point-of-sale terminal or POS, which allows electronic transactions to be carried out through the use of credit cards.

Many shop owners wonder if it is necessary to have both devices or if one is enough for their business. While both provide control over transactions, each has different functions that complement the other.

Purchasing criteria

As with any electronic product, there is a wide variety of makes and models within the cash register market. Before you go out to buy your cash register you should take into account certain elements that will make your equipment last much longer.

Drawer size

When purchasing a cash register you should take into consideration the size of the drawer. This will determine the amount of banknotes and coins it can hold. In addition, the drawer determines the space where the equipment will be placed.

The most advisable is to have a medium-sized drawer, as this will ensure that we have the necessary space to store the money comfortably and securely.

A small drawer is 30 CM long by 30 CM wide by 11 CM high. The medium one is 41 CM long by 42.4 CM wide and 11 CM high. Finally, the large one is 43 CM long by 44 CM wide and 11 CM high.

They can incorporate a scanner or code reader to check the price of the products offered by the shop where you are.

Alphanumeric thermal printer

Each country has specific legislation for the use of cash registers in terms of invoicing. Having a cash register that conforms to the laws of the country is vital to avoid penalties from agencies such as the tax authorities and consumer protection agencies.

To this end, cash registers must be able to clearly print tax data, the number of items purchased, the purchase tax and any discounts, if applicable.

Another point to consider is to buy equipment that can print 2 copies simultaneously, so that both the customer and the shop have a record of the purchase in case of a complaint or internal control

Number of items

Cash registers have the ability to record items with their descriptions, prices and taxes so that correct invoices can be issued. Choosing the right cash register will depend on the business you own and the number of products you want to sell.

On average, cash registers can hold at least 24 products, but there are models where more can be recorded, such as in large department stores or supermarkets.

PC software

Certain models of cash registers can be connected to a desktop or laptop computer for better control of products and prices. This also makes the work faster and easier.

For those who need a cash register, it is very convenient to check which models allow this connection. It is an additional expense, but it will be advantageous for the business in the future.

Ease of use

Having a cash register that provides a user-friendly system will be very useful when programming it. It is important that, when choosing our equipment, we see if the system is easy to understand.

It is also important to know if the manufacturer has a manual in English or if it is possible to download it from their website. This is crucial for those who are not fluent in English and need to programme their equipment. Reading a manual in your language can avoid mistakes in the future.

The manufacturer and warranty

As with any electronic device, there are multiple makes and models, and cash registers are no exception. You should know and study the manufacturer when purchasing the equipment.

We should look for quality equipment that is backed by both warranty and spare parts. And choosing a manufacturer that offers a customer service centre is very valuable for this equipment with which we are going to have a record of our sales and profits.
