With the advent of the Internet era, two-dimensional code scanning module has gradually set off an application upsurge in all walks of life. Following the pace of medical industry reform, two-dimensional code scanning module has become popular in the medical industry.

      The embedded two-dimensional code scanning module (built-in fill light and indicator light) is designed for the development and use of customized products provided by medical equipment, so as to accurately collect and transmit information data of paper bar codes. Two-dimensional code scanning module is the core element to help smart medical care and medical upgrade. It uses embedded scanning module to connect with development board and carry out secondary development to connect with medical barcode system. Two-dimensional barcode has many information contents and strong coding ability, which can encode information such as fingerprints, pictures and texts, sounds, etc., and the two-dimensional barcode information has low cost, error correction ability and stable decoding ability from production to production. By fusing barcode information collection and data transmission performance with two-dimensional code recognition module, real-time communication between medical barcode system and medical care system is established, and patients' condition is tracked and monitored in real time, and medicines are matched. Therefore, the application of two-dimensional code scanning module has been very common.

The case of MSUNG MS-2101 QR code scanning module applied in medical industry is as follows:
       Medical equipment (medical PDA, hospital entrance guard, patient identity authentication, medical self-help, etc.) helps nurses to accurately check medical information and quickly execute doctor's orders by virtue of the medical barcode recognition, acquisition and real-time transmission functions of MS-2101 two-dimensional code scanning module. Medical staff proofread patient identity information, drug distribution and doctor's advice information matching by scanning patient bar code information through handheld medical terminal equipment embedded with MS-2101 two-dimensional bar code scanning module. If medical staff perform mismatch or wrong operation on patients during nursing, they will send out false alarms, which will reduce the pressure and medical risks of medical staff.

The advantages of MASUNG MS-2101 scanning module in medical industry are as follows:
(1) with fill light and indicator light, the paper bar code scanning effect is good;
(2) It is active and small, and it is convenient to embed medical PDA, hospital access control, patient identity authentication, medical self-service, mobile phone, scanner, medical equipment and other terminal equipment;
(3) online status of heartbeat monitoring;
(4) Using wide-angle lens, the scanning code can be pasted closer, which accords with the habit of close scanning;
(5) The optional adapter board can be connected with RS232,TTL3.3V,TTL5V,USB and USB virtual serial ports through terminal wires.
