Smart cards cannot provide locations using GPS services. Two-way communication is used when collisions are detected, and the retransmission is based on a priority of detection. The CSCD protocols sense the carrier frequency of the smart card to match its speed. RFID tags find use in a wide range of applications such as - tracking goods through the supply chain, tracking assets, controlling access into buildings, among other similar applications. The smart card connects to the smart card reader using a unique Radio Frequency ID (RFID) or through a Carrier Sensing Collision Detection (CSCD) system protocol. Then, it sends such information received from the smart card back to the controlling terminal for immediate processing. How does the smart card work?Ī smart card reader connected to a host computer, cloud computer, or any controlling terminal collects the information stored on the microprocessor chip of the smart card. They are mainly plastic, and the microprocessor cards consist of volatile memory and microprocessor components. Smart cards usually have up to 346 kilobytes of ROM, 8 kilobytes of RAM, a 16-bit microprocessor, and 256 kilobytes of programmable ROM. The IC chip on the Smart card can be a microprocessor with memory capacity or a simple memory circuit that processes, manipulates exchange, and stores data. What is a smart card?Ī smart card is a type of pocket-sized device which looks like a credit card but has an embedded Integrated Circuit (IC) that can process data and allow the user to perform any transaction. Smart cards are generally utilized by these countries to implement the cashless economy because they aid the seamless transaction of trade and settlement of other financial instruments.
We live in a technologically advanced era, and as such, advancements in payment infrastructures makes life easier, transactions faster, swifter, and smoother.Īlmost all countries in the world are adopting the cashless economy policy. In this modern age, there’s been a significant improvement in the digitization of traditional payment methods. An independent guest blogger wrote this blog.
