What is the approximate range for reading RFID tags?
375659
Range and sensitivity depends on many things, the most prominent being the total RF power, orientation and the sensitivity of tags. Having said that, this device operates at very low power and for most tags that would be read from 6-8 feet on a regular RFID reader, this device will read them in less than 1 feet. With a less sensitive tag, you can expect the range to be a few inches.

It really depends on the size and power of the reader. I know I've seen some industrial units read a couple feet away. I haven't used this RFID ME reader in a few months but I believe it can read about 4-5 inch gap (maybe).

It's a small range, a couple of inches the most, but also depends of the type of the RFID tag. In some cases it was like we had to physically touch the tag with the reader

We have ours set up on a counter top. The furthest a key tag can be from the scanner is about 10 inches and it works fine at that range.

Nope. Real RF meters measure at MW per square meter. This only reads RFs at MW per square centimeter.

The full range of frequencies, 88.1-107. It's funny that you asked that bc I just read that on the user guide yesterday lol!

I believe within 300-500 fts (not yard b/c 1yard = 3ft). The further away, the signal is weak and sometime it disables itself. It is great within a house (downstair and upstair.) I hope the info will help you in making the selection.

it's NFC short range. you have to put it right up to it. you have to tap it to the plate. you will be lucky if it goes pass 1-2 inches for range. but, best luck I have ever used, and I've used quite a few electric locks.

If aligned correctly about 2 cm. If they are not aligned correctly the reader will detect the RFID card but will not read the serial number
1042299
im not 100% sure without looking. guessing by how small the wires are on the leads, its less that 5. If i remember correctly it was in the range of 1.5 to 3 at the most

If you set the AFS_SEL bit to 3, the full-scale range will be +/-16g. You can't measure anything over 16g or under -16g as the chip will just return 0x7FFF or 0x800, respectively, as those are the ceiling and floor for a 16bit two's complement output in hexadecimal (the output format for I2C on this chip)

No. It reads to whole numbers, like 106, 285, etc. It has a wide range, even reading up to 900 and over.
1674676
Frequency Range: 65-108MHz(FM Receive only), 136-174MHZ and 400-480HZ (TX/RX)

There is a pin seeker mode on the range finder that would help with this. If your hands shake, it will give you multiple readings when it scans but you will easily be able to identity which one is the pin. You shouldn't have any trouble getting an accurate reading.

In an open field, you can expect approximate range of 15-25 miles. If you do not understand the concept of amateur radio, chances are, you should not be buying this equipment.

I bought this for my husband and he has had no problems with reception at his work place. He uses a Blackberry, which we measured for magnetic field. It was a very high reading (7-20 milligauss) when out of the case. In the case it was within the acceptable range. Hope this helps.

My work uses the 125kHz cards and while it doesn't block that signal, it does drastically reduce the range of the card. Normally I can swipe at 4 - 6 inches away from the sensor but with these sleeves it drops the range to 1 - 2 inches.

yes but it is geometric that if you double the distance you reduce the rf to 1/4 strength.the closer your are the higher the reading will be.

It has the ability to pickup a small range of frequencies that police agencies use. This scanner picks up 450-470 MHz. Some agencies use this while others opt to use the 150-160 MHz range. If there is one particular agency that you are trying to monitor, check and see if they fall in the 450-470 MHz range. If so, this will work for you.
