Depends on the antenna, frequency, the reader power, and the design.
Passive RFID's have a range from a few mm's to a few meters.
In general, low frequency = near field rf = short range, higher frequency = far field rf = longer range.
EPC HF near field tags have short ranges of less than 1 meter.
EPC UHF tags are typically 1-2 meters reliable read. Far field range is very complex and it is possible to have multipath reflection arrangements where 10 meters may work... sometimes.
With illegally high power transmitters, and large antennas, far field tags can be reliably read to tens of meters or more for non-commercial designs.
Semi-passive RFID's can be read over hundreds of meters.
Active RFID's are limited only by their transmit power and antenna design.

Why is RFID tags used instead of bar codes use to tag goods?
Both RFID tags and barcodes are used to tag products, but RFID has many advantages. An RFID tag can be read at a distance. That helps with inventorying stock, and also helps to catch shoplifters. Retailers have a problem with shoplifters putting an expensive item in a cheap item's box; because the RFID tag would be on the product itself it wouldn't matter what box it was in.
On an average how many times you can use RFID tags?
The type of RFID tag you are referring to is likely a passive device. It gets read by stimulating it with a certain RF frequency and then looks for a unique return. Hence the tag life is essentially forever.
Are rfid readers writers compatible with all chips?
Yes and no, It is common for companies as Texas Instruments & Phillips to lock their technology. However, most reader/writers are compatible with more than their own company's chip-set. frequency range is however not interchangeable. A 125 kHz reader will never be able to read a 13.54 MHz tag.
What are disadvantage of rfid?
RFID are expensive comparied to BarcodesRFID readers struggle picking up information when passing through metal or liquid.Reader collision can occur where two signals from different readers overlap and the tag is unable to respond to both.Tag collision can occur when numerous tags in the same area respond at the same time.RFID still has two separate chips (read only and readable/writable), which cannot be read by the same machine.
What is a ribbon parameter card?
The "ribbon parameter card" is a little chip that is delivered with every newly bought pack of ribbons. You need to insert this card in the fitting slot of the printer (at the backside I assume), and let the printer read the contents of the chip. Once finished, you can remove the card. You need to follow this procedure for the printer to be able to work with the new ribbon. If you do not have the chip for that ribbon you can not use it.
Can an RFID reader read credit cards?
Yes, an RFID reader can read credit cards that have RFID technology embedded in them.
How do RFID readers read the RFID chip and where does the input go?
I want to build a workflow in Automator and use the RFID chips in a card that have a "product number" and when the reader readers the number it then inputs it into an application that has been setup. So my questions is. When the reader scans the card and gets the "number" where does that "number" go?
What is a RIFD reader?
It's an electronic device that creates an electric field. If that field is distorted by an RFID chip (tag) or card, basically a coil and some electronics, the RFID reader can, from the fields distortions, decipher the data stored on the chip. The data is then transferred to a Microcontroller or Computer for evaluation.
Did Barack Obama cancel the chip?
There was nothing to cancel. It's an internet myth. There never was any chip. This rumor was spread by people who were opposed to the health care law and wanted you to be afraid of it. But the new health care law contains no demands that everyone have an RFID chip or any other kind of chip. I invited you to read it for yourself you see.
RFID?
At Intellistride, we provide advanced RFID solutions that maximize read range and efficiency across industries like logistics, healthcare, and manufacturing.
Are passive RFID tags read-write or write once only?
Passive RFID tags can be both read/write or write-once. They can also be bought pre-written.
What are the factors that affect the reading range of RFID labels?
The reading range of RFID labels depends on several key factors that impact the performance of the RFID tag reader. Here are the main factors affecting RFID read range: RFID Frequency – Different RFID systems (LF, HF, UHF) operate at various frequencies. UHF RFID tags typically have the longest range. Reader Power Output – Higher power output from the RFID tag reader can increase the reading distance but must comply with regulatory limits. Antenna Type & Orientation – The strength and directionality of the reader’s antenna significantly impact how far it can read RFID tags. Tag Type & Size – Passive tags rely on the reader’s signal, while active RFID tags have built-in batteries for extended range. Larger antenna sizes also enhance performance. Interference from Metals & Liquids – Metal surfaces and water can reflect or absorb RF signals, reducing read range. Using RFID solutions designed for metal or liquid environments can help. Environmental Conditions – Factors like humidity, temperature, and physical obstructions affect signal strength and range. Tag Placement – Proper tag positioning on assets ensures better visibility and minimizes signal blockage. Reader Sensitivity & Configuration – A high-quality RFID tag reader with optimized settings can improve read performance. At Intellistride, we provide advanced RFID solutions that maximize read range and efficiency across industries like logistics, healthcare, and manufacturing. Choosing the right RFID system ensures accurate tracking and seamless operations. Want to optimize your RFID implementation? Contact Intellistride today!
How effective is aluminum foil in RFID blocking?
Aluminum foil can be somewhat effective in blocking RFID signals, but it may not provide complete protection. It can help to reduce the range at which RFID signals can be read, but specialized RFID-blocking products may offer better protection.

What are the advantages for RFID?
RFID tags don't need to be positioned in a line of sight with the scanner.RFID tags can be read at a faster rate than barcodes.Can read RFID tags from a distance. Information can be read from a tag at up to 300 ft.RFID tags are read/write devices.RFID contain high levels of security; data can be encrypted, passwordRFID tags carry large data capabilities.Once these are set up; it can be run with minimal human participation.RFID tags are reusable.

How do you read chip resistor?
Use a digital ohm meter as opposed to attempting to read the lettering on the chip. This will give you an immediate value that will fall within the tolerance of the chip resistor.
