A Brief Introduction Of PDA
PDA (Personal Digital Assistant) can help people complete tasks such as working, learning, and entertaining on the go. Classified by usage, PDA can be divided into industrial grade PDA and consumer product PDA. The former is mostly used for industrial applications, while the latter is a consumer product designed for daily use. Industrial grade PDAs are used in various industries, such as manufacturing, transportation, and logistics. They are particularly helpful in monitoring the status of machines and equipment, as well as tracking the location and movement of goods within the facility. Consumer product PDAs are used for various purposes, including managing personal finances and tracking fitness goals. Some models can also be used for placing orders or online shopping. Here, KingTop, a PDA computer manufacturer, aims to give you more information about PDA.
Features Of PDA
With the explosive development of technology, the performance of PDAs has been rapidly improved. The more advanced PDA technology, the more applications developed for it. In addition, more PDA computer manufacturers are endeavoring to produce better PDAs.
PDA has an open operating system, which can support software and hardware upgrading, information storage and so on. These features make PDAs ideal devices for both commercial and personal use. For example, it can be used as a mobile phone to make calls or send messages, used as a calendar to record important events or used as an organizer to manage schedules and meetings. PDAs are also used for entertainment purposes, such as playing games, listening to music, watching videos, and even reading e-books. In addition, PDAs are also used for commercial areas. They can be used as calculators, address books, or calendars, as well as many other applications that help users with their daily work. The personal digital assistant can run multiple applications at the same time, and can easily switch between different tasks when needed; Communication with other devices can be achieved through wired or wireless connections, and data can be shared with other computers (or phones).
Of course, not all PDAs have all the above functions. Even if it is available, it may not be possible to achieve it due to a lack of corresponding services. But it can be foreseen that the trend of PDA development is the integration of multiple functions such as computing, communication, network, storage, entertainment, e-commerce, etc. Some people also call notepad personal digital assistant. Generally, personal digital assistant refers to a palmtop with PalmOS, Windows CE or other open operating systems, which has network functions and can be upgraded by users freely. In addition to expanding hardware, users can also install software and even develop their own programs to run on it.
In terms of usage, it is simpler to operate, more convenient to move, and has practical functions than desktop computers, eliminating the five major limitations of desktop computers, namely: the limitations of mobility, the complexity of usage, the difficulty of mobile networking, the high cost, and the idleness of usage.
The Basic Classification Of PDA
Industrial grade PDAs include barcode scanners, RFID readers and writers, etc. Industrial grade PDA can be used in many fields, they are sturdy and durable.
Barcode Scanner
Barcode scanner, also called barcode reader or barcode scanner gun. This device can be used to read the information contained in barcodes, utilizing optical principles to decode the content of barcodes and transmit it to a computer or other device through data cables or wireless means. Widely used to scan barcodes for goods and documents in many places, such as supermarkets, logistics express delivery and libraries.
Radio Frequency Identification
FID is a wireless technology that uses radio waves to transmit data between readers and electronic tags attached to objects or animals. The tag stores data on its integrated circuit (IC) and transmits it when asked by the reader device, which then decodes the information in the tag. This technology utilizes electromagnetic fields to transmit data between readers and electronic tags attached to objects. This allows objects to be recognized without contact or physical interaction with them. RFID technology is widely used in various fields, such as industrial automation, logistics, and supply chain management.
Ultra High Frequency PDA
Ultra high frequency PDA is used to read RFID tags and has great advantages in reading ultra-high frequency tags. Its main application areas are as follows:
1. Logistics express delivery
It can be used for data collection of delivery personnel's waybill, transfer yard/warehouse, and by scanning parcel barcodes, the waybill information can be directly transmitted to the backend server through 3G modules. Also, it can achieve functions such as querying relevant business information.
2. Logistics delivery
Typical examples include tobacco distribution, warehouse inventory, and postal distribution. Worth developing include terminal distribution from major commodity manufacturers, drug distribution, in factory logistics from large factories, and transportation from logistics companies' warehouses to warehouses.
3. Chain store/store/counter data collection
Used for the collection and transmission of data on the purchase, sales, inventory, inventory, adjustment, return, subscription, and membership management of the store, as well as for the inventory counting of the store.
4. Shoe and clothing ordering meeting
Used for wireless ordering meetings in the footwear and clothing industry, based on WIFI wireless communication technology, on-site ordering is carried out by scanning barcodes through the sales PDA handheld terminal, and order data is wirelessly transmitted to the backend ordering meeting system. The backend ordering conference system is used to send order data from handheld terminals to merchants' warehouses, and then transmit this information to other merchants in the industry through an interface portal. Then, the data is transmitted to the backend system and processed, which will generate a report for the salesperson. If necessary, sales personnel can view order details on the handheld terminal.
5. Card Management
Card management, as the name suggests, is the management of various contact/non-contact IC cards, so the main extension function of the scanning gun used is contact/non-contact IC card reading and writing. In addition, the card management system also supports various types of IC card reading and writing devices. It can be used not only for contact/non-contact IC cards, but also for magnetic cards and NFC tags.
Consumer Product PDA
Consumer product PDA mainly refers to smart phones, personal digital assistant, tablets, etc.
