What is the read range of low frequency mfrc522 RFID tag?
The RC522 RFID module based on MFRC522 IC from NXP is one of the most inexpensive RFID options that you can get online for less than four dollars….Hardware Overview – RC522 RFID Reader/Writer Module.

What is long range RFID reader?
These long range readers are used to interrogate active RFID tags that use the 2.45 GHz and 433 MHz frequencies. Most of the long range RFID readers have an omni-directional antenna which gives a good read range of up to 338 feet (100m), while some of them have an option to attach an external antenna.
There is no one simple answer to this question. Handheld RFID readers can read RFID tags somewhere between 1 and 50+ feet. Fixed readers can read RFID tags up to 100+ feet.
How does a higher frequency affect the RFID range?
Here’s how… In general, the higher the frequency, the greater is the range. RF radiation has more energy at the higher frequencies and so the RF field can influence RFID tags that are further away. Lower frequencies (LF) usually mean shorter RFID range. LF RFID devices use the so-called Near Field Effect.
Between 2m (6.5ft) and 9m (29.5ft) – transponder and antenna dependant. UHF tags can be very low cost (at high volumes) due to the simpler manufacturing process . Read field is much larger than LF or HF, but the radio waves can bounce off objects farther away.
LF RFID devices use the so-called Near Field Effect. This uses the magnetic component of the electromagnetic energy and this couples the tag and reader over only very short distances of typically up to half a meter, or just over a foot.
