00:00So you finally got that fancy smart lock or a fob-based gym door at work, and then you realize
00:04you've got exactly one key card, and the building manager wants 20 bucks for a spare.
00:10Yeah, no thanks. I went down a bit of a rabbit hole this month testing cheap RFID cards,
00:16fobs, and clone tags, and honestly, some of these cost less than a coffee.
00:20So here are my top 5 RFID cards and key tags, with the best deals I could dig up.
00:26Starting with the Classic, a 10-pack of 13.56 MHz M1 Proximity IC cards for $7.35.
00:34That's about 73 cents a card, which is kind of ridiculous when you think about it.
00:40These are the standard blank cards most smart door locks and access systems use,
00:44so you just enroll them in your lock like you would a normal card, and you're done.
00:48Over 4,600 sold with a 4.9 rating, and the print quality is clean, no weird peeling laminate.
00:54If you've got a house full of roommates or an office with turnover, this is the no-brainer pick.
01:00Now if you're not sure what frequency your building actually uses, and trust me,
01:04a lot of people aren't, the 5-YOA dual-chip key fob is the smart move at $5.34.
01:10This thing has two chips inside, a 125 kHz T5577-EM4305 and a 13.56 MHz chip,
01:19so it covers basically every common access system. It's rewritable too, so you can copy an existing
01:25fob onto it, and if you move apartments, just rewrite it. One fob, two frequencies, no guessing.
01:32That's why it's sitting at 4.9 stars with over 4,600 sold.
01:37Next up, if you already know you're on the older 125 kHz standard, don't overpay.
01:43These read-only TK4100 and EM4100 key fobs start at $4.90 for a 10 or 20 pack.
01:51Read-only sounds like a limitation, but it's actually the point, nobody's rewriting or hijacking these,
01:56and most basic access control panels and time clocks just want a fixed ID number.
02:01They're solid little plastic tokens, they clip right onto a carrying, and they take a beating.
02:06It's the cheapest way to get everyone in the building their own tag.
02:10Then there's the one for the tinkerers, the 5YOA CUID Gen 2 Magic Card at $4.42.
02:17This is the card you use when a regular UID clone won't work, because a lot of newer readers now
02:23check for the classic Magic Card backdoor and block it. CUID gets around that.
02:28Pair it with the MCT app on your phone or a proxmark, and you can copy and rewrite it over
02:33and over.
02:35$4 for a card that saves you a trip to the office and a $20 replacement fee, that math works
02:40out fast.
02:41And rounding it out, the bulk option, 50 rewritable 13.56 MHz 0-block UID key fobs for $10.17.
02:50Do the math, that's $0.20 a fob.
02:53If you're an installer, running a small business, managing a gym, or you just do a lot of NFC projects,
02:59this is the one that actually saves you real money.
03:02Writable block 0 means you can set the UID yourself, so cloning and recloning is quick.
03:08$3,500 sold, 4.9 rating, and honestly at this price you can afford to lose a few.
03:14All 5 are linked down in the description if you want to check current pricing, they move around a bit.
