Designed for low power consumption and compact size, it supports SPI interface for easy connection to Arduino and Raspberry Pi boards. With fast data rates up to 424kbit/s and secure CRYPTO1 encryption, this kit is ideal for developers building smart meters, access control, and portable devices. The package includes three modules, blank S50 cards, and key rings, making it a cost-effective, ready-to-use solution for RFID projects. ## Description RC522 chip 1. MFRC522 is a highly integrated read and write chip which is applicable to 13.56MHz contactless communications. 2. It is a non-contact read and writer card chip, low voltage, low cost and small size, is a better choice for smart meters and portable handheld devices development. 3. MF RC522 completely integrated in all types of 13.56MHz passive contactless communication methods and protocols. 4. Support 14443A compatible transponder signals. The digital part handles ISO14443A framing and error detection. In addition, support fast CRYPTO1 encryption algorithms, terminology validation MIFARE products. 5. MFRC522 support MIFARE series of high-speed non-contact communication, two-way data transmission rate up to 424kbit/s. 6. As a highly integrated 13.56MHz card reader new family of chips, there are many similarities between MF RC522, MF RC500 and MF RC530, but also have many differences. Communication between it and the host SPI mode helps to reduce the connection, reduce PCB board size and cost.

No issues at all. Placed inside an ABS box they easily read mifare cards held about half inch away on the other side (interfaced with an Arduino nano). Well worth the money. Review: All three readers worked right out of the box, and with no defects. A great value. - As soon as the tag readers arrived and the pin headers were soldered on, I uploaded the "firmware check" sketch to my Arduino and wired them up one reader at a time, and all three readers passed the initial testing. I then wrote up a quick sketch to provide audible confirmation, and to display tag information on a 20x4 I2C character display. All three cards and all three key fobs scanned with no issues. I do look forward to doing more experiments with these RFID readers and tags. For $10, it was a great value. ## Features - The MF522-AN module design the circuit of card read by using the original Philips MFRC522 chip. - Easy to use, low cost, and applicable to equipment development and card reader development etc. - Applicable for the user who need to design or manufacture the RF card terminal. - The module can be directly loaded into the various reader molds. - The module use a voltage of 3.3V, it can connected communication with user's any CPU mainboard through several lines of SPI interface, it can ensure stable and reliable work, and reader distance. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07VLDSYRW | | Best Sellers Rank | #199 in Single Board Computers (Computers & Accessories) | | Brand | HiLetgo | | Customer Reviews | 4.4 4.4 out of 5 stars (171) | | Date First Available | July 24, 2019 | | Item Weight | 2.18 ounces | | Item model number | 3-01-0490-3pcs | | Manufacturer | HiLetgo | | Number of Processors | 1 | | Operating System | Linux | | Package Dimensions | 5.2 x 3.78 x 0.83 inches | | Processor Brand | ARM | | Series | RFID Kit | | Wireless Type | Radio Frequency | ## Product Details - **Brand:** HiLetgo - **CPU Manufacturer:** ARM - **Connectivity Technology:** SPI - **Model Name:** RFID Kit - **Operating System:** Linux ## Images ![3pcs RFID Kit - Mifare RC522 RF IC Card Sensor Module + S50 Blank Card + Key Ring for Arduino Raspberry Pi - Image 1](https://m.media-amazon.com/images/I/61hOZghM+RL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent product. *by T***P on July 8, 2025* They work as expected. No issues at all. Placed inside an ABS box they easily read mifare cards held about half inch away on the other side (interfaced with an Arduino nano). Well worth the money. ### ⭐⭐⭐⭐⭐ All three readers worked right out of the box, and with no defects. A great value. *by J***S on August 21, 2024* As soon as the tag readers arrived and the pin headers were soldered on, I uploaded the "firmware check" sketch to my Arduino and wired them up one reader at a time, and all three readers passed the initial testing.

For $10, it was a great value. ### ⭐⭐⭐⭐ Work good *by B***. on January 21, 2024* Hooked these up to an ESP8266 as a fun project. I intend to make it so these cards can open our garage as we already have a deadbolt lock that can scan cards to unlock. Range seems good and was pretty easy to hook up with a little research on SPI. I do wish they had I2C support out of the box. ## Frequently Bought Together - HiLetgo 3pcs RFID Kit - Mifare RC522 RF IC Card Sensor Module + S50 Blank Card + Key Ring for Arduino Raspberry Pi - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects - YARONGTECH RFID Sticker tag 13.56mhz Round 25mm Adhesive Back -50pcs --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/151651024-3pcs-rfid-kit-mifare-rc522-rf-ic-card-sensor-module](https://www.desertcart.co.uk/products/151651024-3pcs-rfid-kit-mifare-rc522-rf-ic-card-sensor-module) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-31*
