What is the 4442 contact chip card?
    The 4442 contact chip card isSmart card manufacturingOne type of chip inside is mainly used for sensing purposes, such as access control sensors, card readers in school cafeterias, and card readers on buses. These devices all use contactless cards, and 4442 may have been misunderstood by some people while searching. Actually, the correct one is the 4442 contactless chip card. It is a contactless card and contactless, while contactless cards are used4428 contact smart cardHere, I also corrected some misunderstandings from friends searching. Its main features are: 256×8-bit EEPROM, direct byte addressing, 32-bit low-address 32-byte data with irrecoverable write-protected bits, 32-bit protected bits, write operation end flag, reset response compliant with 7816-3 standard, byte erasure and write time of 25ms, minimum write erase cycle of 10,000 times, data retention period of 10 years.
    The above are the main features of the 4442 contactless chip. At the end of the article, I want to emphasize again that the 4442 is an inductive card, that is, a contactless IC card. My title is just set to meet the needs of users searching.
