New Concept of Linfiny Digital Paper for B2B

Digital Paper has three basic applications; Note taking app, a PDF viewer app, and an NFC tag cooperation app.
In addition to this basic function, we have optimized the system to be able to acquire not only data recorded by on-site workers, but also information such as handwriting stroke meta information and operation history on workers’ terminals.

Therefore, customer can obviously progress the improving efficiency by digitizing general field operations, and in addition to by linking and analyzing the acquired data with higher-level systems, we believe our Digital Paper can bring so many values for your true operational management innovation for companies and workplaces, and even creates new business and service models.

Our basic SW enhancement approach for DX on-site operations is not to develop a specific application software exclusively for customer requirements.
Our development concept is to make it possible to embed various information that customers want to obtain information in the field work into PDF forms by maximizing the various functions that PDF has. That makes it possible to operate seamlessly existing data recording at worksite and the data analysis by AI server.





Generous storage

32GB of internal memory (Approx. 24GB usable) lets users carry and access up to 10,000 PDF documents.

Auto save

Annotations and hand-written notes are automatically saved to internal memory and easily searchable.

Long-lasting battery

On a single charge, lithium ion battery enables use for up to 5 days with Wi-Fi/Bluetooth turned on, and up to three weeks with Wi-Fi/Bluetooth turned off.

Actual performance varies based on settings, environmental conditions, and usage. Extensive handwriting and/or continuous connection with Bluetooth or Wi-Fi will draw more power and require more frequent charging.
