julọ 413 DNA jẹ ifọwọsi bi NFC Forum Type 4 Tag and is also compliant to ISO/IEC14443-4, ISO / IEC 7816-4 file structure and APDUs format. Thanks to the high input capacitance (70pF), julọ 413 DNA tag IC is particularly tailored for applications requiring small footprints, without compromise on performance. Small NFC tags can be more easily embedded into e.g. product labels or electronic devices. The mechanical and electrical specifications of NTAG 413 DNA is tailored to meet the requirements of inlay and tag manufacturer.
