Payment of state duty (by UIN) - is there an API?

Question

API

Colleagues, producing some micro-web services for the commercial part for the convenience of using great state ideas (including implemented ones), stumbled upon an interesting point: payment of the state fee (for UINs). Do not confuse with SMEV x!
My rather long research showed that input forms (on websites and in personal accounts) of banks and electronic wallets began to appear.
Having delved into the process, I found that there is a bank in the northern capital that supplies its services to the gosuslugi portal in terms of processing matched charges for paying the state fee, and there is some bank in the capital, I did not find it in open historians. It turns out that they provide integration services for anyone who wants to have a form for entering UINs in their solutions for correct payment. Of course, with a transaction fee, and, of course, with a monthly service fee.
At the same time, having requested documentation from the first one, I received a Talmud with the name Kazna API with a bunch of rest methods.
Honestly, the profit is incomprehensible in the ease of use of my solution, so I didn’t get to the elaboration, but the cost is decent.
Actually, it’s interesting if anyone has experience in implementing state duty payments in commercial products, and it’s also interesting to know what the Kazna API is, how banks with quiet names provide such services (I suspect they participate in interdepartmental interaction through SMEV, well, ah, then it’s business technology).
Are there sane services for embedding into your solutions at an affordable price, why is it so difficult to find something on this topic, or have you not learned to search for many years on your own.

Answer 1

SSD - any SATA 2.5" 256 GB for system and software
Then there will be 2 disks in the laptop: SSD for the system and software, and HDD for files. Put the SSD inside, HDD in the basket. If necessary, change the HDD to a hot DVD.
Regarding memory.
0. Open the laptop, look at the type and frequency, order the same, but larger volume, the same frequency, or more
1. You can download CPU-Z (portable enough), it will show the type, frequency of memory and the number of slots
2. Look at the specification for the processor on the Intel website, and find out how much memory it supports.
And that's why.
For modern Intel i3 / i5 / i7 processors, the memory controller is integrated into the processor itself (it used to be on the motherboard in the north bridge), so for modern laptops and desktop computers, the processor itself, and not the laptop manufacturer, is responsible for limiting the maximum possible amount of memory / motherboard. The motherboard also limits only the number of slots for installing memory.
Further, the official manual and information on the site, for example, for my laptop (Acer 5830TG) said that a maximum of 8 GB can be put into it, however, the specification for the processor indicated that my i5-i2450m supports 16 GB.
Check the Intel website for your processor (CPU-Z will tell you the exact model) or write to Intel technical support with a request for max memory support. On my i5-i2450m processor, the page immediately says "Max Memory Size (dependent on memory type) - 16Gb"
3. The memory frequency can be more, but not less than the currently installed memory OR the minimum supported. This affects pricing, "old" 1333 MHz bars are more expensive than "new" 1600 MHz ones. In any case, the memory frequency will be limited by the bus frequency, and the memory does not care at what frequency to work LOWER (I have a standard bus frequency of 800, and the standard memory that was installed is 1333)
As a result, for example, if I followed the guide from the Acer website, then I could put a maximum of 1333 MHz and 8 GB. And so I installed 16 GB with a frequency of 1600 MHz (1600 was simply cheaper than 800/1000/1333 with the same volume, but it still works at 800 MHz). It's been a normal flight for a year now.
PS I have 2 Kingston 2Gb DDR3 1333 MHz SoDIMM modules lying around (only one module for 200 pins, the other for 204 pins). I can give anyone for a couple of delicious dark beers in Moscow =)
