Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. An RFID system consists of a tiny radio transponder called a tag, a radio receiver, and a transmitter. When triggered by an electromagnetic interrogation pulse from a nearby RFID reader .

An RFID system consists of a tiny radio transponder called a tag, a radio receiver, and a transmitter. When triggered by an electromagnetic interrogation pulse from a nearby RFID reader device, the tag transmits digital data, usually an identifying inventory number, back to the reader.
An RFID interrogator (also called an RFID reader) and RFID antennas are two of the major hardware components that make up an RFID system. Depending on the specific application, interrogators and antennas are configured differently to optimize tag read rates.RFID interrogators use different methods to communicate with RFID tags depending on whether the RFID system is active or passive. Passive and semi-passive tags use passive backscatter to communicate. The item being tracked is called a "tag" and nearly always requires no battery or other power source, which differentiates RFID from all other wireless communications schemes. RFID provides a non-contact way of collecting information about a product or device.

The active tags range from 300 to 750 feet. Although active tags are essential for applications that require longer read ranges, they are also vulnerable to radio intrusion and noise interference. The size, weight and price of active tags are more comprehensive than other tags.An interrogator is the RFID component that collects information from tags and sends it to a host system. The process of collecting the information from the tags is called reading the tags, and for this reason an interrogator is also called a reader.Passive vs. Active RFID. Understand what factors go into choosing an RFID tag for your project such as frequency, size, form factor, standard, durability and attachment method. At a simple level, RFID systems consist of three components: an RFID tag or smart label, an RFID reader, and an antenna. RFID tags contain an integrated circuit and an antenna, which transmit data to the RFID reader (also called an interrogator).
An RFID tag or transponder, an RFID reader or interrogator, and an antenna make up the three essential parts of an RFID system. The tag has an antenna and a microchip that holds data about the item it is linked to.
Active RFID systems have three essential parts – a reader or interrogator, antenna, and a tag. Active RFID tags possess their own power source – an internal battery that enables them to have extremely long read ranges as well as large memory banks.An RFID system consists of a tiny radio transponder called a tag, a radio receiver, and a transmitter. When triggered by an electromagnetic interrogation pulse from a nearby RFID reader device, the tag transmits digital data, usually an identifying inventory number, back to the reader.

Your reader probably powers the NFC tag through induction, which then transmits the info back to the reader. Probably in the realm of micro watts. The next issue is the compromised antenna. .
