In addition to the basic functions, the handheld terminal also has some other functions, which are closely related to the specific application and system, and also need to be considered first in the selection of handheld terminals.
1. Barcode scanning: At present, there are two technologies for barcode scanning: laser and CCD. Laser scanning can only read one-dimensional barcodes, while CCD technology can recognize one-dimensional and two-dimensional barcodes. The popular view is that when reading one-dimensional barcodes, laser scanning technology is faster and more convenient than CCD technology.Handheld terminal with barcode scanning function is usually calledBarcode Handheld Terminal 。
2. IC card read-write: The handheld terminal integrated with IC card read-write function is usually called IC card handheld data terminal, which is mainly used for IC card card management
3、Contactless IC cardRead and write: The handheld terminal integrating contactless IC card read and write function is usually called contactless IC card handheld data terminal, which is mainly used for contactless IC card management.
4. Built in information button: the so-called information button is a built-in non-contact IC card chip, mainly used for patrolling.
5. Fingerprint acquisition and comparison: the handheld terminal integrated with fingerprint acquisition module is mainly used for public security, social security, etc
6. GPS: The industrial application is mainly used for public security, and more importantly for the civilian market, providing electronic maps and positioning services for drivers
7. GSM/GPRS/CDMA wireless data communication: the main function is to exchange real-time data with the database through wireless data communication.This function is mainly used in two cases: one is applications that require high real-time data, and the other is applications that cannot store the required data in the handheld terminal due to various reasons. The required data may be too large, or it may need confidentiality.
8. GSM/GPRS/CDMA short message communication: almost all handheld terminals supporting wireless data communication support short message communication. The reason why this function is listed is that some handheld terminal products only support short message communication. The real-time performance of this function is slightly lower than that of GSM/GPRS/CDMA wireless data communication, and sometimes it may lose real-time performance due to the SMS server,Unless you rent a dedicated SMS server, and the overall data bandwidth is very small in the communication process.
9. GSM/GPRS/CDMA wireless voice communication: This function is mainly used for voice calls, and can replace walkie talkies to some extent after secondary development.
10. Infrared data communication (IrDA): As the earliest short-range wireless data communication technology, this function is almost standard in various handheld terminals at present. Except some mobile phones and few handheld terminals, most handheld terminals include this function.However, it should be noted that not all the handheld terminals purporting to support IrDA really support IrDA. Many handheld terminals only implement the physical layer specifications given by the IrDA Association, but not the IrDA protocol stack, which is not recognized in the official standards of IrDA.
11. Infrared data communication (power infrared): the power infrared protocol is a standard issued by the Ministry of Electric Power of China, which is used for data communication between power equipment. The reason why this function is mentioned here is that a large number of domestic meter reading machines are equipped with this function.
12. Bluetooth communication: Bluetooth communication function is a new generation of short-range wireless communication technology. At present, it is mainly used in PDA and mobile phones.Other data terminals are also gradually using this technology. Short distance Bluetooth communication can reach 10m, long distance Bluetooth communication can reach 100m. When the amount of communication data is not large,Bluetooth technologyIt can also replace 802.11B networking.
13. RS232 serial communication: as the most basic data communication mode, basically all handheld data terminals have this function.
14. RS485 serial communication: RS485 is used for long-distance serial communication technology, and only a few special handheld terminals have this function.
15. USB communication: USB communication technology is adopted by many handheld terminals at present due to its fast communication speed, especially PDA, which is mainly used for data exchange with PC.However, USB communication is not equivalent. USB devices are divided into master devices and slave devices. The master device can only communicate with the slave device, and cannot communicate with the master device. Therefore, few handheld terminals can be used as both USB master devices and USB slave devices.Buyers are prone to misunderstandings in this regard, believing that as long as both devices support USB, they can.
16. 802.11B: 802.11B asWireless LANThe current development speed is very fast. Many handheld terminals have been equipped with this function. Handheld terminals with this function can network in a relatively large range and exchange data with PCs, servers, etc., and can exchange wireless data in large enclosed spaces (such as factory buildings, warehouses).If the space exceeds the coverage range of the wireless signal, multiple nodes can be added.
17. Print: some handheld terminals integrate the print function, and can print documents directly.
18. Handwriting recognition: the input function of handheld terminal is always very weak compared with PC, industrial personal computer and other devices. Handwriting recognition can alleviate this problem. If users need a lot of text input, they must have this function.
19. Chinese character input: for some handheld terminals without handwriting recognition function, if you want to input Chinese characters, this function is essential, and the input method should also be considered. Full spelling is outdated, and T9 is relatively more acceptable.
20. For other functions, some handheld terminals have other functions, such as photographing, pluggable CF card, pluggable SD card, etc., which need to be selected according to the user's needs.

The main mobile application fields in China are as follows:
logistics
Typical products include tobacco distribution, warehouse inventory and postal distribution. What is worth developing are terminal distribution of major commodity manufacturers, drug distribution, factory logistics of large factories, and warehouse to warehouse transportation of logistics companies.
The logistics system uses different handheld terminal expansion functions according to different systems, mainly including barcode scanning, contact/non-contact IC card reading and writing, 802.11b, Bluetooth data communication, etc.
The handheld terminal can be used for the data collection of the dispatcher's waybill and the data collection of the transit yard/warehouse. By scanning the express bar code, the waybill information can be directly transmitted to the background server through the 3G module. At the same time, it can realize the query of relevant business information and other functions.
Three meter reading
In the foreseeable future, this is a market with large capacity.
The extended functions integrated in the three meter meter reading machine are mainly power infrared, barcode scanning, data communication, etc.
Demand for meter reading in power industry:
Manual transcription is error prone and time-consuming;The manual card meter reading mode is illegible, and it is easy to make mistakes when copying data to the PC, and meter reading personnel only estimate and read without arriving at the site, which cannot be accurately counted. Meter reading personnel are prone to "human information electricity" for familiar households, which greatly reduces the work efficiency in the manual operation mode.
Solution：
With cameras, on-site pictures are shared in a timely manner, so that managers can understand the real-time situation and strengthen decision-making.GPS positioning is used to ensure the patrol is in place;The meter reading personnel can easily and efficiently complete the work by checking the model and recording. At the same time, the electric power department can more accurately calculate the electricity consumption.
Mobile government, mobile police
When strengthening the police through science and technology is more than just a slogan, the technology content of police equipment is getting higher and higher. In particular, the traffic police, patrol police and criminal police have also begun to equip mobile data devices, including handheld terminals, which provide the police with a more powerful tool for police enforcement.In addition to the police, the current health, urban management, tax and other administrative departments are also trying to use handheld terminals to standardize administrative business and improve administrative efficiency.
The functions of the handheld terminal used by the mobile police station mainly include GPRS/CDMA data, voice communication, IC card reading and writing, and fingerprint acquisition and comparison may be required in the future.
Mobile transaction
When there are more and more transactions and the counter space is no longer enough for quick transactions, or the trading place itself is short of counters, the only choice is to choose mobile transactions, such as KFC, McDonald's, ticketing on the train, stadium ticketing, parking fees, etc.
The functions required by mobile transactions vary according to different occasions. The various extension functions described in section 1 may be used.
Insurance
For example, mobile insurance system and home payment of pension insurance.
The functions required by the handheld terminal of the mobile insurance system include GPRS/CDMA data or SMS communication, etc.The extension function of the handheld terminal required for pension door-to-door payment is mainly fingerprint collection and comparison.
Wireless order

The extension functions of the handheld terminal used by the wireless ordering system mainly include 802.11b, Bluetooth data communication, etc
Card Management
Used to manage various IC cards andContactless IC card, such as ID card, membership card, etc
As the name implies, card management is to manage various contact/non-contact IC cards, so the main extension function of the handheld terminal used is contact/non-contact IC card reading and writing.
Patrol management
It is mainly used to standardize the route when the security guards and patrolmen of the community perform patrol tasks.The hand-held terminal used for patrol management generally integrates information buttons.
Warehouse management
Chain stores/stores/counters are used for the collection and transmission of data such as purchase, sales, storage, inventory, adjustment, return, subscription and membership management.
The shoes and clothing order meeting is used for the wireless order meeting in the shoes and clothing industry. Orders are placed by scanning the barcode through the handheld terminal.
Swipe card when parking on the road
When the vehicle enters the parking space, the license plate number and parking space of the vehicle will be recorded on the POS machine, and the vehicle information will be automatically stored in the database.When the vehicle is ready to leave the parking spot, the POS machine will also automatically call the owner a second list, which will display a series of information such as the name of the parking spot, license plate number, parking time, charging standard, actual charging amount, etc.The actual amount paid by the owner is automatically calculated by the system according to the parking time of the vehicle, accurate to seconds.
There are other mobile applications that I am not familiar with.

There are many manufacturers of handheld terminals, and each manufacturer's naming of products is diverse, inconsistent, and sometimes ambiguous, which is easy to cause confusion for users and businesses.The author here wants to name these handheld terminals just to provide some convenience for users when selecting models.
data collector
so calleddata collectorIt refers to handheld terminals with barcode scanning function, but not all handheld terminals with barcode scanning function are called data collectors. The operating system of the data collector is usually developed by the manufacturer. Pocket PC, PALM and other handheld computers with barcode scanning function are not called data collectors.
Due to historical reasons, the data collector has various names:
Counting machine: At first, this kind of product was used for counting, so it was called counting machine
Mobile POS: The name is very strange, and PDA and IC card handheld terminals used in some industries are also called mobile POS machines. In fact, except for mobile transactions, applications in other occasions have nothing to do with POS;
bar codedata collector: This should be the most accurate name at present;
Data collector: Taiwan's name;
The above are several common names, and some are not commonly used: such as barcode handheld terminal, handheld terminal collector, handheld barcode data terminal, data acquisition terminal, etc.It can read one-dimensional barcode and two-dimensional barcodeBarcode Handheld Terminal
IC card handheld terminal
Integrated contact/Contactless IC cardThe handheld terminal with read-write function is called IC card handheld terminal, also called handheld IC card terminal, handheldIC card reader/writer, hand-held IC card data collector, etc
Mobile communication data terminal
Mobile communication data terminal is a name coined by the author. At present, no manufacturer has used this name.As the name implies, mobile communication data terminals are handheld terminals that can realize mobile communication. These products are similar to mobile phones, but different from mobile phones, they are mainly used in systems in some industries because they have some functions that mobile phones do not have, such as barcode scanning, IC card reading and writing, etc.
PDA/mobile phone/smart phone
The reason why these three different products are described together is that these three products used to be civilian goods.With the downturn of PDA in the civil market, many PDA manufacturers have begun to vigorously expand the industry application market, which has also driven the application of mobile phones and smart phones in the industry market.The common feature of the three products used in the industry is that they use common operating systems, such as POCKET PC, PALM, SMARTPHONE, SYMBOLIAN, LINUX, Android, etc., and have a large number of development groups.
Handheld fingerprint acquisition terminal
The handheld fingerprint acquisition terminal is a handheld terminal that integrates fingerprint acquisition and comparison functions.Fingerprint handheld terminal has the function of fingerprint collection and identification, and is widely used in finance, banking and other fields with high security requirements.
Meter reading machine
Strictly speaking, meter reading machines cannot be classified in this way, because the previous products are classified according to their own characteristics, while meter reading machines are classified according to their uses. However, the name of this handheld terminal has always been the same, and has not changed, so the author will call it that.
Meter reading machine is a handheld terminal used for reading meters in public utilities (water, electricity, gas, and heating in the future).The meter reading machine used for power meter reading usually integrates the power infrared function. The other is a handheld terminal with only basic functions, some with barcode scanning function.
