Compatibility and ordering

One pack contains 100 parent cards, equivalent to 300 tags. Check chip and UID compatibility, and confirm your printing workflow supports three-part cards.

Match the full product reference to an existing credential or your access-system specification. A shared card size or radio frequency does not by itself establish reader compatibility. If your current card type is uncertain, contact ACB before ordering so the required reference can be checked.

Questions about MIFARE Classic EV1 3-Up

Does a pack contain 100 or 300 usable tags?

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.

What should I check about the identifier type?
