The NTAG215 (504 bytes) is the industry standard for digital business cards. It provides ample space for a complete vCard, profile photo URL, and social media links, ensuring fast and reliable taps across all modern smartphones.
Yes, but you must select the NTAG215 option. The Nintendo Switch system requires the exact memory size (504 bytes) of the NTAG215 chip. NTAG213 and NTAG216 will not work for Amiibo cloning.
Absolutely. Because the NTAG213, NTAG215, and NTAG216 comply with the NFC Forum Type 2 Tag standard, they are universally compatible with all NFC-enabled Android devices and iPhones (iPhone 7 and newer) without needing a third-party app to read basic URLs.
Yes, all three chips are read/write by default. They can be rewritten over 100,000 times. You can also permanently lock them (read-only mode) to prevent data tampering, or secure them using the built-in 32-bit password protection feature.
Yes, as an OEM factory, we offer high-speed automated bulk encoding. You simply provide an Excel or CSV database with your URLs, UIDs, or vCard data, and we will pre-program every card before shipment.
