What is an RFID reader RFID interrogator?

An RFID reader is also known as an interrogator. The main objective of an RFID reader is to transmit and recieve signals , transforming radio waves from tags into a format that computers can read. Most readers are able to read and write a tag. The reading function reads data stored in the tag´s chip.

Which is a part of an RFID interrogator?

An interrogation zone (or read zone) consists of the RFID reader (or interrogator), antennas, cables, peripherals, and the environment in which the equipment is installed.

Can I use my phone as an RFID scanner?

Yes, you can use your phone as RFID tag. For Android or Windows phones you enable NFC. Traditionally a RFID tag is a smart card, badge, ticket or drop. Nowadays, the smart phone can be used as RFID tag as well.

Which is not a part of an RFID interrogator?

An inlay is not a part of an RFID interrogator but is part of an RFID tag. The power amplifier, controller/processor, and oscillator are parts of the RFID interrogator; therefore, answers A, B, and D are incorrect.

What is RFID controller?

RFID controllers are simple and easy to use RFID technology-based hardware component that efficiently reads radio-frequency identification (RFID) tags, which enables to open door locks.

Which is not part of RFID interrogator?

Is RFID technology expensive?

Handheld RFID readers can cost anywhere between $1,250 to $20,000 each, depending on the level of automation offered. Active RFID readers are the least expensive option at 1,250 to $1,500 each. Passive and handheld RFID readers are more expensive, with costs ranging from $3,000 to $20,000 each.

What makes up an RFID interrogator and antenna?

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. Typical configurations consist of portals, arrays, and tunnels.

What is the range of a low frequency RFID reader?

Low frequency (LF) 125 kHz RFID readers interrogate RFID tags at a close proximity, with a read range of up to 10cm (some special readers may read tags from an extended distance of up to 1m). Due to the LF 125 kHz reader’s lower sensitivity to radio wave interference, these readers are often used in configurations where metal and water are present.

How are RFID tags read in a forklift?

RFID tags are read by stationary and handheld readers. At the top, the reader antennas are the square, yellow units on the left. The forklift in the middle has its own readers, and handheld readers like the one at the bottom are used in both retail and warehouse applications.

What’s the distance between a RFID reader and an ID badge?

The maximum distance between the reader’s antenna and the vary, depending on application. Credit cards and ID badges have to be brought fairly close to the readers, somewhat like barcodes. For other applications, passive RFID can be read up to approximately 10 feet away, while active with batteries can be several hundred feet from…
