PDA is a common data acquisition equipment, used in warehousing, logistics, industry, clothing, catering and other industries. PDA has many functions, common are: bar code scanning, NFC reading and writing, RFID identification, fingerprint recognition, photography and other functions. Fingerprint recognition as a way to take data, is also gradually known by enterprises.

In the PDA specification parameters, fingerprint recognition generally has two kinds, one we commonly known as "small fingerprint" also known as mobile phone fingerprint, one is we commonly known as "big fingerprint", what is the difference between these two fingerprint recognition?

N60 "Small Fingerprint"

Both kinds of fingerprint identification can play the role of information confidentiality and protection of user information security. "Small fingerprint" recognition, similar to fingerprint recognition on mobile phones, is usually designed under the home screen of the device or on the back of the device. By inputting the fingerprint information of the operator, the device can be unlocked by comparing the fingerprint, which limits the use of the device by others.

S80 "Big Fingerprint" recognition

"Big fingerprint", fingerprint recognition can not only meet the basic needs of fingerprint unlock, it also plays another important role -- fingerprint information collection. Fingerprint information collection function, it is used more widely, such as hotel management, enterprise attendance management, banking services. According to the communication mode and working principle, the common "big fingerprint" can be divided into serial port fingerprint, USB fingerprint, FBI fingerprint, capacitor fingerprint, optical fingerprint, etc.

Blovedream S80 industrial intelligent handheld terminal adopts the recognition mode of capacitor fingerprint, which can facilitate users to collect information and expand many usage scenarios.

Blovedream S80 fingerprint recognition parameters are as follows:

Operating frequency :120MHz

Collection area :12.8* 11.6mm

Resolution :508 dpi, pixel matrix: 192*192

Extraction format :BMP format

Security encryption: instruction is clear code communication, data encryption for custom

In general, when choosing a PDA device with fingerprint recognition, it is necessary to know whether the fingerprint recognition is a simple fingerprint unlock function or need to expand other application scenarios.
