Java POS Systems – An Overview

Retailers are increasingly replacing their aging cash registers with Java POS systems. A number of retailers are either deploying or piloting Java POS systems, and they say the software runs on any hardware or operating system and is easy to modify as their needs grow. Depending on the additional systems choices made, some have reported decreasing implementation and support costs.

JavaPOS is a standard for interfacing point of sale software using the Java programming language. These desktop applications help facilitate payments from customers and track sales. The Java programming language is designed to have very few dependencies, meaning software developed with it can run anywhere and on any device.

Java is a general-purpose programming language that allows programmers to build programs that can run on all platforms without the need to recompile.

This essentially gives applications built using Java the advantage of seamlessness and easy adaptability within a wide range of working environments. So, JavaPOS applications are built to run easily on all kinds of hardware.

This, in turn, means reduced POS terminal costs, platform independence, scalability, and reduced administrative costs.

The modern retail POS system in Java fulfills a lot of roles and integrates with virtually all aspects of your business’s operations. It usually comes with a clean interface and a cloud-based operating system, which allows multiple users to use it at any point in time.

It saves a lot of man hours in the areas of employee management, inventory and account reconciliation. It also supports virtually every back-office technology such as QuickBooks, Freshbooks, Salesforce, and so on.

The brand you decide to go for will depend largely on your business needs and specifications. From restaurants to bars and all models in between, choosing the ideal Java POS system for your business will be based on your specific needs.


JavaPOS was developed by a committee consisting of Sun Microsystems, IBM, and NCR. The committee first met in April, 1997, and the first release of Java POS 1.2 was issued on March 28, 1998.

The final release as a separate standard version (version 1.6) was released in July 2001. Starting with the release of version 1.7, a single standard document was released by its UnifiedPOS committee.

How to Choose Features In Your Java POS

Yes, it can be pretty confusing to decide on which features/components you need in your Java POS software, as the technology space is rapidly evolving.

Our recommendation for you is to start with the core features by asking yourself what the absolute necessities are for your business in a point of sale system. Questions like, do you need it to be mobile and handheld or okay with just a stationary device? Do you need a very rugged system, or do you want a sleek machine? What is the volume of transactions you are looking at processing in a day?

Some common features being searched for by users include:

Customer Management 

The benefits of understanding customers can be up to 20% every year, according to different published studies. Java POS systems offer an easy way to track customer purchases.

Furthermore, government agencies and manufacturers can manage controlled products and substances easily by verifying customer IDs and capturing data.

Retailers can predict the next purchase based on customer purchase history. Furthermore, Java POS automates incentive permits for items not on their shopping list. Moreover, Java POS solutions allow tracking and calculation of sales commission. The system adds potential customers automatically by scanning their driver’s license and photo proof.

General System Settings

There are industry-specific presets available in an advanced Java POS, such as appliances, grocery, hardware, jewelry, natural products, vitamins, and supplements, sports and archery products. The general system feature offers a user setup option. Retailers can control what users can see based on the presets and functions for each industry.


With Java POs, retailers save time and money by providing reports. The reports can be used to generate purchase orders, and purchase advice reports are created based on sales and inventory levels. In addition, it allows retailers to forecast their sales probability, adjusting past customer purchase history and future purchases accordingly.

Accounting Interface

This integration helps accounting-specific products to generate generic outputs from Java POS systems.
