![]() The RFID card powered to work by the electromagnetic energy received that transmitted from RFID reader. RFID card usually is using passive RFID technology without an internal power source. In simple, every RFID card embeds with an antenna that connected with an RFID IC, hence it can receive, store and transmit data via radio waves. If the physical properties define RFID card out of RFID tag, it is the technical attributes of RFID card make itself unique from other card shape products. ![]() Technical properties and how RFID card works There are many additional crafts available, such as serial number printing bar code or QR code printing (generate according to UID) or magnetic stripe attach etc. RFID card could be pre-printed with intricate artwork via offset printing, digital printing or screen printing. An example of those already in the market is wooden RFID card, however the much higher cost limits the scope of application. There are already trends for solution finding of plastic substitutes, that to use Bio-polymers or none plastic material of different forms as the base material for card making. ![]() PET ( Polyethylene Terephthalate) is the 2 nd most commonly used plastic polymer for card making due to its highly durable and heat-resistant. The most commonly used plastic polymer is PVC (Polyvinyl Chloride) due to its durability, flexibility and versatility for card making. The majority of RFID Card is still using plastic polymers as the base material. There are other dimensions available, which as known as customized dimensions. The thickness of RFID card varies from 0.5mm-1mm depend on the different production processes and customer needs. The primary RFID Card dimensions are known as “standard credit card” size, which named ID-1 or CR80 that codified by the International Organization for Standards in the specification document ISO/IEC 7810 (Identification Cards–Physical Characteristics). The RFID card is distinguished with its obvious physical characteristics and used for specific applications. ![]() ![]() If RFID Tag is the general description of RFID transponders that to receive, store and transmit data with RFID reader via radio waves. What is RFID Card and how does it works? Here are explained from two aspects of physical properties and technical properties.
