These days we use the internet for work and for entertainment alike, and because it is so convenient we tend to overlook one thing: more and more of our data now lives online.
Many people do not know how to keep their own data online safe from hacking and leaks. So it is understandable that some are still hesitant about using an online POS in their business.
Let us look at the security on Qashier POS, and at how its several layers of protection improve on an offline POS — starting by understanding the difference between an online and an offline POS system.
Online POS vs offline POS
An offline POS system is one that works without an internet connection, storing all of its data on the device itself. Updating the system and backing up the data has to be done by hand.
An online POS system such as Qashier, meanwhile, connects to the internet to work more effectively, storing all transaction data securely in the cloud so users can reach it from anywhere. An online POS also updates itself automatically and syncs data in real time, which keeps everything running smoothly when you work across several branches or locations.
And here is the security on Qashier POS that lets a shop be confident it can sell and keep its data safe.
1. Dynamic QR payments: confidence the amount is right and nobody is being cheated
One of the security strengths of using Qashier's online POS is Dynamic QR payment. Unlike an ordinary static QR code, a Dynamic QR is effectively single-use: the data is set afresh for every transaction, which guards against forgery and fraud.
With a Dynamic QR, when the customer scans to pay, the amount due appears on their side based on the actual purchase. The customer never types a number in themselves, so you can be sure they pay the right amount — no worrying about the sharper sort of customer entering the wrong figure on purpose — and checking it afterwards is easy too. A win on both counts.
2. A real-time sales dashboard: transparency at your fingertips
Qashier's system has a dashboard showing sales in real time. You can see it on the POS terminal or in the app, and on QashierHQ, the online back office, as well. The dashboard makes it easier to check that everything adds up and to understand your sales better.
Because it is an online dashboard you can open it from anywhere online. An owner or a shop manager can go in, check the figures and put any mistakes right quickly.
The real-time dashboard is also a powerful analysis tool, letting you look at sales data in detail and put that data to use later — another part of the security on Qashier POS.
3. User permissions: control over who sees and changes what
With Qashier's advanced user permission settings, owners and administrators can tailor access for each member of staff individually, so you can be confident that each person only reaches and edits the data their role calls for.
For example, a member of staff working the till can be set to reach nothing beyond ringing up sales, while a manager can reach both sales and inventory data. Permissions like these let you keep your data strictly confidential.
Setting access rights also keeps the business running in an orderly way and reduces the risk of a data leak or of data being handled incorrectly.
4. Google Cloud, with security at the leading edge
Qashier is not only a set of features that make running a shop easier. It runs on Google Cloud, which brings Google-grade security with it:
Real-time AI security: the power of AI detects and blocks threats before they land. The system can identify potential threats or anomalies by analysing patterns across large volumes of data, and where an anomaly or a malicious activity has occurred before, the system recognises it and blocks it automatically.
Detection and security protocols: Google Cloud's Chronicle Security Operations adapts smoothly across environments — the cloud, your organisation, and your various data sources. Data from every source is protected, with threats responded to, so you can have the highest confidence in the security of your business.
5. The PCI DSS standard: the best in payment security
Many people will not have come across it, but PCI DSS is the standard for "payments" — the same one VISA works to. It is designed comprehensively so that any company accepting, processing, storing or transmitting credit card data can apply it. Data is kept secure, shielding against the vulnerabilities that credit card transactions can open up, and reducing the risk of a data breach or of fraud.
With PCI DSS, the same payment security standard VISA holds to, you can be confident that Qashier's payment system is secure and reliable.
*Credit card payments in Thailand can be processed through card terminals (EDC) provided by leading banks, so you can rest easy with international standards and PCI DSS there as well.
6. Protection against threats: DOS attacks and others
Another part of the security on the Qashier POS terminal is protection against DOS (Denial of Service) attacks, which are becoming more widespread in today's digital world. An attack of this kind aims to load a system so heavily it can no longer be used, or to obstruct it from working effectively. Disruption like that halts trading, which costs sales or leaves customers unhappy — and does long-term damage to a brand's reputation.
Recognising how severe and how frequent these threats have become, Qashier has taken steps ahead of time to strengthen its defences. Beyond the usual security measures, Qashier uses advanced mechanisms built specifically to counter DOS attacks. They are designed to identify and halt anomalous events on the system, such as unusual traffic or unusual volumes of requests, which keeps operations from being interrupted.
7. Encryption second to none: keeping customer data safe
Qashier understands how important it is to protect customer data. That is why we use high-grade data encryption to protect it — giving your customers more confidence and your business more credibility.
For Qashier, encryption is not only a matter of security. It is a genuine promise to look after what we hold. Using high-grade encryption lets you be confident that customer details are encrypted against unauthorised access, so that even if the data were intercepted by someone with bad intentions, they still could not open it or make any use of it.

Qashier's rigorous approach to keeping data safe does more than let businesses use an online POS to run their shops smoothly — it also gives customers confidence in the brand. The world is moving towards the digital and the online, and with Qashier you can run your business securely as it does.
