Into DIY tech projects or customizing your gaming experience? This pack of 50 blank NFC 215 cards is super handy. You get 25 square cards (about the size of a credit card, 85x54mm) and 25 round coin-sized cards (30mm diameter), all made from durable white PVC that's waterproof and durable. They're compatible with TagMo and Nintendo Amiibo, so you can program them for games, automate phone tasks, create smart business cards, access control, or whatever you can think up. Each tag has 504 bytes of memory, which is enough for URLs, text, or simple triggers. They work with NFC-enabled Android phones—just tap to read/write. Note: they're not for inkjet printers, but you can label them with markers or use a compatible card printer. A fun, affordable way to experiment with NFC technology, whether you're a hobbyist, developer, or gamer looking to expand your collection.
