Excuse me, how does RFID reader communicate with MCU?
Single chip microcomputer generally uses RS232 interface to communicate with readers. The following readers have RS232, and you can also customize interfaces such as network port, Wigan interface, USB and RS485.

High frequency:

Short-range reader generally refers to the desktop YX7036SR-A, which has a reading distance of 0-5cm and supports dual protocols.

Medium distance reader generally refers to the reading distance of 5-30cm, such as YX909 1T, which is more suitable for this application.

Long-distance readers generally refer to the reading distance of 30- 120cm, like YX929 1T, so if the antenna and tag are well matched, they can read further.

extremely high frequency

A close-range reader generally refers to a desktop YXU9806 with a reading distance of 0-50cm, just like this.

Medium-range readers generally refer to images YXU 186 1-8dbi with a reading distance of 50-600cm, which is more suitable for this application.

Long-distance readers generally refer to the reading distance of 600- 1200cm, such as yxu1861-12 DBI. If the environment and labels are well matched, you can read further.
