There is a kind of online part-time data entry job at home and abroad called: captcha human bypass. Many friends who are looking for money on the Internet have more or less come into contact with this term, but they know the origin and origin of this task. There are only a few of them. Coding is to mark a product with a number or barcode, which contains various information about the product. It is an automatic identification technology produced and developed in the application practice of computers. ◆It is designed to realize automatic scanning of information. It is an effective means to collect data quickly, accurately and reliably ◆The application of coding technology solves the problem of data entry and data collection and "bottleneck", and provides strong technical support for supply chain management ◆Input speed is fast ◆Information Large quantity ◆ High accuracy ◆ Low cost ◆ Strong reliability Coding technology provides us with a way to identify and describe items in logistics. With the help of modern technical means such as automatic identification technology, POS systems, and EDI, enterprises You can know where the product is in the supply chain at any time and respond immediately. [Edit this paragraph] How to choose the right coding and labeling Until you have plans to adopt new packaging materials or customers have new requirements, labeling and coding may not be among your priorities. For example, customers now require durable coding or clear signage, and it's critical to understand all of your options before choosing the right technology. With or without careful analysis, the results are very different. With it, smooth and efficient operation can be achieved without experiencing unnecessary failures and causing customer dissatisfaction. Key factors to consider include: · The type of material or substrate being marked; · Production capacity or speed required for the operation; · Print quality: durability and clarity; · The maximum expense your company is willing to spend; · Total running costs , which includes repair costs and the cost of consumables such as ink and ribbon; · Whether variable data, graphics and barcodes are required. Once you understand these factors, choosing the most suitable marking and coding technology is easier. Laser coding, thermal transfer overprinting (TTO), and binary array inkjet printing are all beneficial options for a variety of situations. [Edit this paragraph] Coding development Laser coding Industrial laser marking began in the early 1970s and has developed into a complete technology since then. Today, production lines using laser marking and coding can be found all over the world. Lasers can be used to mark digital codes, 2D matrix and barcodes, logos and symbols on labels, sleeves, glass and plastic bottles, cans, metal drums, tubes, blisters, cardboard, tube films and container lids. Generating codes with a laser requires no ink, stamps or ribbons. In the new sealed CO2 laser coder, infrared laser light is generated by radio frequency discharge of a carbon dioxide gas mixture. CO2 laser systems work by changing the surface color of the substrate (e.g. PVC packaging), melting, foaming (e.g. polyethylene terephthalate bottles) or removing the surface of the material (e.g. printed labels, cardboard, cans, hoses) , coding using thermal etching method. The advantages of laser coding include: fast speed, versatility, long-lasting coding, non-contact operation, clean dry process, thousands of hours of maintenance-free operation, extremely low operating costs and adaptability to fully automated production lines. Laser coders' unrivaled uptime and superior production capabilities deliver cost savings in a variety of situations. [Edit this paragraph] Related questions 1. First, let’s talk about what the verification code is. Verification code: the abbreviation of (Fully Automated Turing Test to Tell Computers and Humans): CAPTCHA, full name: Completely Automated Public Turing Test to Tell Computers and Humans Apart from that, the purpose of CAPTCHA is to distinguish a program algorithm between computers and humans. This program must be able to generate and evaluate tests that humans can easily pass but computers cannot. This requirement itself is a paradox, because it means that a CAPTCHA must be able to generate a test that it cannot pass on its own.

Nowadays, the verification code (captcha) systems of major international websites such as Hotmail, Google, and Yahoo have been cracked by programs one by one! 2. Spam, large dating websites, and shopping websites all need to bypass the "abominable" barrier of verification codes when sending advertising messages. a. Some spam and advertising message senders have hired people to create programs that automatically identify and crack verification codes. These people don't need to design projects to manually crack verification codes. b. Some spam and advertising message senders do not use programs to automatically identify and crack verification codes, so these people need to develop a separate project for manually cracking verification codes (captcha human bypass project). So there is the so-called "coding" task. 3. Most of the general coding tasks are for batch registration of various email accounts and accounts for large communities, dating, videos, and shopping websites. In addition, if the verification code is encountered when sending advertising messages within the site, it also needs to be cracked. Domestic mailboxes include 163, sina, yahoo, sohu, 263, Tom, 126, 21CN, yeah, etc. The main international ones are gmail, hotmail, yahoo, and aol. 4. Who will become a part-time employee engaged in online coding tasks? Worker? Almost all of them are hard-working Internet poor people from third world countries. Why? The reason is simple. Only hard-working poor people would value such low-cost online part-time jobs. Poor countries such as my country, India, Bangladesh, Pakistan, and the Philippines have participated in the arduous work of coding. 5. Why is there a difference between changing the IP and not changing the IP for the coding task? Because whether it is an email site or a large community, dating, video, or shopping website, registration is restricted. For example, an IP is only allowed to register a maximum of 1-10 accounts in a day. 6. Why do most coding tasks in China require changing IPs, while almost all coding tasks abroad do not change IPs? The reason why foreign coding tasks do not change the IP is because they rent an independent server and cooperate with the IP proxy to operate. Domestic coding tasks do not rent any server or use an IP proxy, and rely on the coder's own conditions (ADSL broadband users) to change the IP! 7. Why are the prices of coding tasks getting lower and lower? Because there are more and more email and website account providers, competition is becoming increasingly fierce, which will inevitably lead to price drops. Just like there are more manufacturers of refrigerators, the price of refrigerators will naturally fall. 8. Why do my hotmail, gmail and other international mailboxes often receive emails such as advertisements, "sending money", and making hundreds or thousands of yuan a day? Because there are still many people engaged in manually cracking verification codes, or you are also engaged in coding! ! ! Okay, this ends the introduction to the origin of the coding task.
