Anyone with some technical skills and an understanding of the principles can crack the data and modify information by simply drilling a hole in the back of the machine and threading a few wires.
Hackers are impossible to defend against; the key lies in the hacker's mindset.
After GPRS is implemented, Xing Baohua will also need to install POS machines for various merchants.
POS systems typically have a policy of receiving funds the next day, commonly known as reconciliation, but in reality, they earn overnight interest fees.
This is a huge number.
In addition, Xing Baohua used the bank's name to promote POS, and Qian Huizhi planned to transfer the money to the bank account.
The more likes it gets, the more likes it gets.
Convenient and fast services are essential to retaining a large user base.
Just like the ATMs in this case, although they have been around for more than a decade, they do not rely on electronic data for settlement, but on receipts.
It seemed simple at the time, but the reconciliation process was very complicated and troublesome later on.
Moreover, the amount is limited. You can only withdraw the minimum three-digit amount each day.
Take 100 yuan; it's for emergencies.
They still need to verify the printed data with the bank before they can make the transaction from their accounts.
Limiting withdrawal limits is also a way for banks to avoid risk.
Often, when customers lose or cannot find their receipts, they will deny the transaction. And since there are no security cameras, many people are not satisfied with just the bank's record.
How can you prove that a customer has withdrawn money?
Connecting to the internet makes all the difference; transactions can be completed quickly within the user's account.
This is why Xing Baohua went to great lengths to build a network in the small city of Hong Kong.
Even if there are no conditions, he will create them.
After all that quiet planning, there will eventually be a bountiful harvest.
Based on Xing Baohua's proposal, the IC system team found a new direction.
They will improve the software system and find and patch vulnerabilities.
Not to mention their numerous vulnerabilities, even computer systems of that era were riddled with vulnerabilities.
Back then, the U.S. Department of Defense built ARPANET, which was breached by a 15-year-old boy.
This kid is Kevin, the number one hacker.
He is now about the same age as Xing Baohua.
This guy has completely smeared the US Department of Defense and the FBI.
This shows how terrible the original system was. Fixing the bugs was only a temporary solution; only continuous upgrades could bring about real change.
Defense is always a passive approach.
A day later, Xing Baohua organized software personnel and established a software department.
This department will continue to expand and will be divided into two main departments: the Systems Department and the Application Software Department.
They even secretly set up a hacking team to constantly find bugs and attack the systems developed by the systems department.
With more manpower available, Xing Baohua's workload was greatly reduced, and he personally led the team to develop Java.
Under the current conditions, only Java, which is simple, compact, multi-directional, and portable, can be installed in small devices.
It can even be used to create desktop applications.
Moreover, considering the current conservative approach, Xing Baohua wanted to use a microcontroller to create an embedded system.
It has many drawbacks, but also quite a few advantages?
The biggest drawback is that it's a bit bulky, and it requires memory chips that Xing Baohua brought back from Samsung.
It would need to be connected in parallel to expand to about 128m to accommodate it.
This presents a new challenge. Therefore, Xing Baohua and his team must minimize the system's complexity.
First, try installing the system on 64MB of RAM and see if it can run perfectly.
It tests not only the hardware, but also the optimization of the software.
