This work demonstrates how the change in the state of an RFID tag IC from passive to battery-assisted passive (BAP) as an indicator for sensing is particularly well suited for transduction mechanisms that produce charge, such as electrochemical reactions through a case example in glucose sensing.Polymeric humidity sensors are divided into two fundamental categories according to the dom-inant sensing mechanisms [7]: resistive-type and capacitive-type. The former reacts to moisture variation by changing its conductivity, while the latter is sensitive to water vapor by varying its dielectric constant [8].Fig. 1.

Security. NFC payments are generally considered secure. They often incorporate encryption to protect sensitive information such as credit card numbers. Additionally, many smartphones require authentication (such as a .NFC, which is short for near-field communication, is a technology that allows devices like phones and smartwatches to exchange small bits of data with other devices and read NFC-equipped cards over relatively short distances. The technology behind NFC is very similar to radio-frequency identification . See more
