A quantitative measurement kit for heavy metals using a smart card and mobile application.

Abstract

OCR 07AP The quantitative cadmium detection kit using a smart card and mobile application is designed to be able to... It is easy to use, portable, and inexpensive, consisting of a test kit, a smart card, and an electronic device. Supports near-field communication. Measurement is performed by mixing the sample solution with buffer and then establishing a connection. A smart card and electronic devices that support near-field communication are used to insert electrodes and measure the substance. For example, the experimental results are expressed as cadmium concentration values. This invention can be used for detection. Numerous samples are screened at the testing site before being used with larger instruments to confirm the results. Final step
