What's the difference between PDA(handheld computer) and smartphone？

Handheld computers—also known as personal digital assistants (PDAs)—are a small and portable, mobile and smart device with same functions and features as computer, but smaller and easier to take than computer.Although the terms “handheld computer” and “PDA” are often used interchangeably, handhelds tend to be larger and feature miniature keyboards, while PDAs tend to be smaller and rely on a touch screen and stylus for data entry.

PDA, it has not only the functions of a smartphonelike 4G, WIFI, GPS, Bluetooth, make/receive calls, take pictures..., but only there are many optional extended feature, for example Barcode Scanning，Qrcode scanner, RFID/NFC, UHF RFID Reader/Writer， HF RFID Reader ， LF RFID， NFC， Fingerprint, PSAM etc.

    

PDA is suitable for various industries like healthcare, clothing, warehouse, supermarkets, logistics and express, warehouse management, restaurants, hotels etc. And they can generally be used as Healthcare Access Information solution, mobile care solution, stock-take, Real-Time Blood Bag Track And Trace With RFID Tag，Warehouse Management System etc.

In the past few years, the number of PDAs purchased and used by American companies has steadily declined, and more and more companies are investing in other handheld devices, especially smart phones. Smart phones are high-tech phones that have wireless capabilities, Internet connectivity, and usually have the same keyboard functions as PDAs.

Since smartphones can be used to manage emails, edit spreadsheets and notes, and search the Internet using the same interface as a real handheld device, it is an easy step for companies to distinguish between PDAs and new technologies, which also makes They can answer the phone. Since phone calls and text messages can be sent in areas where wireless technology is not provided, and email can be used in areas where phone service is not provided, these devices are considered to be more versatile.
