RFID
How does RFID work? A Radio-Frequency IDentification system has three parts: A scanning antenna A transceiver with a decoder to interpret the data A transponder – the RFID tag – that has been programmed with information. The scanning antenna puts out radio-frequency signals in a relatively short range. The RF radiation does two things: It provides a means of communicating with the transponder (the RFID tag) AND It provides the RFID tag with the energy to communicate (in the case of passive RFID tags). This is an absolutely key part of the technology; RFID tags do not need to contain batteries, and can therefore remain usable for very long periods of time (maybe decades). The scanning antennas can be permanently affixed to a surface; handheld antennas are also available. They can take whatever shape you need; for example, you could build them into a door frame to accept data from persons or objects passing through. When an RFID tag passes through the field of the scanning antenna, it detects the activation signal from the antenna. That “wakes up” the RFID chip, and it transmits the information on its microchip to be picked up by the scanning antenna. In addition, theu0026hellip;
NFC
Contactless Near Field Communication Near Field Communication (NFC) is used mostly in paying for purchases made in physical stores or transportation services. A consumer using a special mobile phone equipped with a smartcard waves his/her phone near a reader module. Most transactions do not require authentication, but some require authentication using PIN, before transaction is completed. The payment could be deducted from pre-paid account or charged to mobile or bank account directly. Mobile payment method via NFC faces significant challenges for wide and fast adoption, while some phone manufacturers and banks are enthusiastic, due to lack of supporting infrastructure, complex ecosystem of stakeholders, and standards. NFC vendors in Japan are closely related to mass-transit networks, like the Mobile Suica used on the JR East rail network. Osaifu-Keitai system, used for Mobile Suica and many others including Edy and nanaco, has become the de-facto standard method for mobile payments in Japan. Its core technology, Mobile FeliCa IC, is partially owned by Sony, NTT DoCoMo and JR East. Mobile FeliCa utilize Sony’s FeliCa technology, which itself is the de-facto standard for contactless smart cards in the country. Other NFC vendors mostly in Europe use contactless payment over mobile phones to pay foru0026hellip;
