Security Manufacturer programmed 7-byte UID for each device Pre-programmed Capability container with one time programmable bits Field programmable read-only locking function ECC based originality signature 32-bit password protection to prevent unauthorized memory operations NFC Forum Tag 2 Type compliance NTAG21x IC provides full compliance to the NFC Forum Tag 2 Type technical specification and enables NDEF data structure configurations. Anticollision An intelligent anticollision function allows to operate more than one tag in the field simultaneously. The anticollision algorithm selects each tag individually and ensures that the execution of a transaction with a selected tag is performed correctly without interference from another tag in the field. main feather of Ntag213 Contactless transmission of data and supply energy Operating frequency of 13.56 MHz Data transfer of 106 kbit/s Data integrity of 16-bit CRC, parity, bit coding, bit counting Operating distance up to 100 mm (depending on various parameters as e.g. field strength and antenna geometry) 7-byte serial number (cascade level 2 according to ISO/IEC 14443-3) UID ASCII mirror for automatic serialization of NDEF messages Automatic NFC counter triggered at read command NFC counter ASCII mirror for automatic adding the NFC counter value to the NDEF message ECC based originality signature Fast read command True anticollision 50 pF input capacitance EEPROM 180, 540 or 924 bytes organized in 45, 135 or 231 pages with 4 bytes per page 144, 504 or 888 bytes freely available user Read/Write area (36, 126 or 222 pages) 4 bytes initialized capability container with one time programmable access bits Field programmable read-only locking function per page for the first 16 pages Field programmable read-only locking function above the first 16 pages per double page for NTAG213 or per 16 pages for NTAG215 and NTAG216 Configurable password protection with optional limit of unsuccessful attempts Anti-tearing support for capability container (CC) and lock bits ECC supported originality check Data retention time of 10 years Write endurance 100,000 cycles Appliacation: Smart advertisement Goods and device authentication Call request SMS Call to action Voucher and coupons Bluetooth or Wi-Fi pairing Connection handover Product authentication Mobile companion tags Electronic shelf labels Business cards     Packaging & Shipping  1000~5000pcs/roll   Shipping way: By express,by sea,by air,China post,  Epacket To USA,Russia,AU,UK     Our Services  Accept small trial order  More shipping way optional  Fast delivery  Customized printed    Photos reference:    NFC sticker   NFC Epoxy tag     NFC Silicone tag     NFC Watch wristband
