Key Technical Features:<\/span><\/h3>\n

Operating Frequency and Communication Mode:<\/strong> The TK4100 operates within the 125 kHz low-frequency band and employs contactless inductive communication. It derives its operating power and receives clock signals via an external antenna coil, thereby enabling self-powered operation.<\/p>\n

Data Structure and Encoding:<\/strong> The chip features an internal 64-bit Read-Only Memory (ROM). Its data format consists of a 9-bit start sequence (all 1s), 40 data bits (comprising an 8-bit manufacturer code and 32 bits of user data), 14 bits for row and column parity checks, and a 1-bit stop bit. It supports various modulation schemes\u2014such as Manchester encoding\u2014to ensure accurate and reliable data transmission.<\/p>\n

Low-Power Design:<\/strong> The chip integrates internal resonant capacitors and rectification circuitry, eliminating the need for an external power supply or buffer capacitors. It can be activated solely by the alternating magnetic field generated by a card reader; its extremely low power consumption makes it ideally suited for long-term applications.<\/p>\n

Physical Parameters and Durability:<\/strong><\/p>\n

The standard dimensions are 85.5 \u00d7 54 \u00d7 0.84 mm (closely resembling the size of a bank card). The cards are typically constructed from PVC or ABS and support various custom form factors, such as keychain cards.
\nThe sensing distance generally ranges from 3 to 10 cm, though the specific range is influenced by the performance capabilities of the card reader.
\nFeaturing a wide operating temperature range of -40\u00b0C to +85\u00b0C, the cards possess waterproof, shock-resistant, and corrosion-resistant properties, making them suitable for use in a variety of harsh environments.<\/p>\n
