00:00Alright, if you've ever tapped your credit card on a reader and thought I want to build that, this one's
00:04for you.
00:05I dug through the listings, compared prices, ratings, and thousands of real orders, and pulled together the top 5 wireless
00:12modules for Arduino RFID projects.
00:15Some of these cost less than a coffee.
00:18Let's get into it.
00:20Starting with the PN532v3 kit, and this is the one I'd hand to a friend who's brand new to NFC.
00:27What makes it stand out is that it speaks three protocols out of the box I2C, SPI, and HSU serial,
00:33so whatever pins you've got free on your Uno, you're covered.
00:36It comes with the S50 card and a key fob tag, so you're not ordering extras after the fact.
00:42$5.50, nearly $4,800 sold, and a straight 5-star rating.
00:47If you want one module that just works with almost any board, start here.
00:52Next up, basically the same PN532v3 chip but at $4.49, and here's the kicker, the seller actually provides the
00:59schematic and the library.
01:01That sounds boring until you're 3 hours deep debugging a wiring diagram at midnight.
01:07Having the real schematic means you can trace every pin instead of guessing.
01:11It also does Android phone extension, so you can read and write from your phone to your project.
01:17Cheapest PN532 on this list, 5 stars, $4,700 sold.
01:22Great value.
01:24Now this third one is the wildcard, and honestly my favorite pick for tinkerers.
01:29It's the TZT kit, and instead of locking you into one chip, you choose RC522, PN532, or RDM6300.
01:38That means you can grab the 125 kHz RDM6300 for old-school access cards, or the 13.56 MHz options
01:46for modern NFC.
01:48And the RC522 version starts at $1.11.
01:53$1.
01:54It ships with tags, does SPI read and write, works with the UNO and the Mega.
01:59At that price, buy three and don't worry about frying one.
02:04Fourth is another PN532 v3, and the reason it earns a spot is the bulk option, you can order anywhere
02:10from 1 to 10 pieces.
02:12If you're building a multi-door access system, or teaching a classroom, or just tired of waiting two weeks between
02:17orders, this is the practical choice.
02:20Same PCB antenna, same reader-writer mode, same I2C, SPI, and HSU support.
02:26$5.84 each, 5-star rating, over $4,500 sold.
02:31Buy the pack, save the shipping headache.
02:34And rounding out the list at $5.03, this one sold as a complete one-set user kit.
02:40Card, fob, headers, module open the bag in your building.
02:44It's the middle ground on price, it's got a 4.9 rating across 4,500 orders, and the reader-writer
02:50mode means you're not just scanning tags, you're writing your own data onto them.
02:54That's the difference between a toy project and an actual working access system.
02:59All 5 links are down in the description, prices checked and updated.

03:10Catch you in the next one.
