The studio image identifies this card family for illustration. Cards are supplied to the stated product specification; the illustrative branding is not a custom-printing service. The stated pack quantity determines what is supplied.
The stated pack contains 100 parent cards, each divided into three key tags, giving 300 tags. Each tag has its own chip and attachment hole. Use parent-card quantities when ordering and check that the production workflow supports the three-part format.
This offer specifies the four-byte NUID version of MIFARE Classic EV1 1K. Match that identifier type and the application configuration to the reader. Do not infer a seven-byte UID or a different chip family simply from the memory size.
