Dive into the world of NFC with this pack of 20 blank NTAG215 cards from Origin-Joy. These are white, credit-card-sized (85.5 x 54 mm) tags made from durable, waterproof PVC. Each card has an NTAG215 chip with 504 bytes of storage, which is the specific type needed for creating your own Amiibo figures for Nintendo Switch (using the TagMo app on Android). They're also great for tons of other NFC projects: you can program them with your phone to automate tasks (like turning on lights, opening a website, or connecting to WiFi), use them for access control, business cards, or product info tags. They're rewritable many times (over 100,000 cycles), but note: once you lock them as \read-only\ or write an Amiibo, you can't edit them again. They work by simply tapping them to the back of an NFC-enabled smartphone. A fantastic, affordable toolkit for tech hobbyists, gamers, or anyone wanting to experiment with smart technology.
