MIFARE Classic 4K IC specifications
| Specification | Details |
|---|---|
| Semiconductor IC | MIFARE Classic 4K |
| Interface / protocol | 13.56 MHz ISO 14443 Type A |
| Catalog memory class | 4 KB nominal memory class |
| Memory allocation | Application capacity depends on sector or file overhead and the selected IC revision |
Memory and protocol values describe the IC. Actual read performance depends on the finished antenna, enclosure, reader and operating environment.
Match the complete part number, reader command set and data format before qualification. Frequency alone does not establish interoperability.
Integration and qualification
Confirm the reader protocol, supported commands, identifier format and application memory layout. If the application requires authentication, align the reader and issuing system with the selected IC and security configuration.
Check key ring attachment, handling and scan orientation. Assess the fob alongside keys and other metal objects under normal use.
Approve an encoded sample in the finished application before volume production. Define acceptance criteria for identification, memory access, printed data and repeated operation.
Define your production requirement.
