Review: RFID system for a good price! - This is the 2 pack RFID RC522 module for the Arduino. The RC522 reads cards with a 13.56MHz frequency. This product comes with both straight and angled Berg connectors, depending on the application. The video shows one of them in operation with an SSD1306 OLED and an 8 relay module. The relay is normally hooked up to a door latch solenoid (not pictured). When the correct card is read, the relay triggers the solenoid, and the door is unlocked. The wrong card keeps the door closed and sends an SMS to security. You can use these modules to control/restrict/monitor access. You can use them (like I will later), to trigger a hidden compartment for an escape room. You have a few ideas. Now order your own set and let's see what you do!
Review: Worked perfect - You do need to solder the header onto the board. If you have never soldered before you should buy a kit with soldering gun and solder (here is a basic one: https://smile.desertcart.com/LDK-Soldering-Adjustable-Temperature-Replacement/dp/B083L8BXRC/ref=sr_1_12?dchild=1&keywords=soldering+iron+kit&qid=1586384692&sr=8-12). It works good at a reasonable price.

## Questions & Answers

**Q: Does this product come with the jumper wires that are in the main image? They do not show up in the description.**
A: Hello, yes, the RFID RC522 module comes with the jumper wires, like the picture shown, now it shows in the description.

**Q: How fast does it read?**
A: Once you have started monitoring, it reads as fast as the Arduino can refresh.  (9600 bits per second) You do have to be pretty close to the reader though. Probably within about 1/2 inch.

**Q: How quick does it take to read and process the info at that distance?**
A: It processes almost instantly (refresh is 9600 bits per second), but your rfid tag has to be pretty close to the board. Like less that 1/2 inch.

**Q: I am wanting to use this reader for my chickens.. how close does the tag have to be to the reader?**
A: About 3 inches.
