Some POS systems resemble PCs, whereas others are more like a tablet device or a smartphone. No matter what type of basic hardware you choose, you'll often have the choice of add-ons to customize your POS system to your way of working.
Here are some of the most popular hardware additions for a POS system:
If a business accepts payment via cash or check, a secure cash drawer is essential for safety and confidentiality.
Cash drawers range in size with different numbers of compartments, so consider what percentage of your income comes from cash to determine how large a cash drawer you need.
A cash drawer with a check slot can make it easy to store checks safely until they can be cashed.
Barcode scanners can reduce the time taken to complete a sales transaction as staff can scan an item to see it on the point of sale monitor. A scanner also reduces human error by ensuring the correct item has been selected.
If your business plans to use a point of sale system for stock management, a barcode scanner also makes it easier to track new products entering the premises.
If a business sells restricted products such as alcohol, cigarettes, knives, or any other item that requires identification, an ID checker could be essential.
An ID checker can determine whether an ID is legitimate and can quickly calculate a buyer's age based on date of birth. This reduces the risk of human error and ensures the business is operating within legal guidelines.
Credit Card Reader
Business owners can choose to use a card swiper or a chip and pin reader. However, while card swipers have historically been more popular, chip and pin machines are fast becoming the best option because they are much more secure.

If you do use a card swiper to capture credit card data, you'll probably want to include a signature capture pad too.
This pad enables customers to sign on an electronic sheet, allowing the signature to be checked against the card signature digitally rather than manually. This is also beneficial if you opt to accept chip and sign transactions.
Customer Facing Display
A customer facing display shows your customer the details of each sale. The most important information for the customer is the item description and the cost, both of which can be displayed on-screen.
A customer facing display reduces the chance of any misunderstanding about price and avoids embarrassment.
If a business processes transactions away from a cash register, a handheld terminal is essential. Using either wireless technology or cell networks, a handheld terminal can connect to the business and client bank while on the move.
A receipt printer provides customers with proof of purchase and creates a paper trail of sales. A single receipt printer will suffice for simply printing receipts, but if you're looking to print other items, such as vouchers and reports, a double printer enables you to complete transactions faster.
You'll find that many point of sale systems include a touchscreen monitor, while others retain a physical keyboard. This is a matter of personal preference.
In businesses where sales values are based on individual weights, such as at a post office or a greengrocers, you can reduce human error by using a weighing scale. A weighing scale can accurately weigh an item and share information with the point of sale system to calculate the correct total.
