The Bolt Card. On 17th May, we announced The Bolt Card - the world’s first contactless Bitcoin Lightning card. “Using a standard NFC card, the Lightning Network and LNURL, The Bolt Card enables a user to simply tap their card on .

Passive RFID tags utilize an induced antenna coil voltage for operation. This induced AC voltage is rectified to provide a voltage source for the device. As the DC voltage reaches a certain level, the device starts operating.Passive RFID systems are composed of three components – an interrogator (reader), a passive tag, and a host computer. The tag is composed of an antenna coil and a silicon chip that includes basic modulation circuitry and non-volatile memory.In RFID applications, the antenna coil is an element of resonant circuit and the read range of the device is greatly affected by the performance of the resonant circuit. Figures 12 and 13 show typical examples of resonant circuits formed by an antenna coil and a tuning capacitor.
Radio Frequency Identification (RFID) systems use radio frequency to identify, locate and track people, assets and animals. Passive RFID systems are composed of three components – a reader (interroga-tor), passive tag and host computer. The tag is com-posed of an antenna coil and a silicon chip that includes basic modulation circuitry and non .Traditionally, passive transponders operate at 125 kHz or. 13 MHz using coils as antennas. These transponders operate in the magnetic near field of the base station’s coil antenna, and their reading distance is typically limited to less than 1.2 m, e.g., 22 cm with a 9-cm.Passive RFID—The Basics. Passive RFID Tags. Passive RFID tags contain a low-power integrated circuit (IC) attached to an antenna, and are enclosed with pro-tective packaging (like a plastic card) as determined by the application. On-board memory within the IC stores data.
Every RFID tag has at least 3 components: RFID Antenna - The antenna absorbs RF which is used to power the tag. RFID Chip - The chip is the brains of the RFID Tag and is used to facilitate data processing. RFID Substrate - This is the material that the antenna and chip and placed onto. The RFID chip system architecture is designed to carry and transmit a unique identification seamlessly by integrating three essential components: the RF Transceiver, Detection Section, and Control Section. RF Transceiver. The RF Transceiver consists of an antenna and an impedance-matching circuit. All modern RFID reader ICs take care of the entire RF front-end (excepting the antenna) and handle all of the modulation and message passing. The IC's interface is entirely digital using a conventional parallel or serial bus.The MCRF200 is a passive Radio Frequency Identifi-cation (RFID) device for low-frequency applications (100 kHz-400 kHz). The device is powered by rectifying an incoming RF signal from the reader. The device requires an external LC resonant circuit to receive the incoming RF signal and to send data.
