MIFARE Classic® 4K NXP EV1 Cards with Magnetic Stripe - Pack of 100

MIFARE Classic 4K magstripe cards

MIFARE Classic 4K magstripe cards combine the listed NXP EV1 contactless chip with a high-coercivity magnetic stripe. This pack contains 100 cards for an application that approves both technologies. Match the identifier and sector setup alongside the stripe requirements before preparing a coordinated card-printing and issue process.

Understand the 4K memory format

NXP specifies a 4 kB EEPROM with sector-based access management for the Classic EV1 4K chip. Card-management information and sector keys occupy part of that memory. The contactless interface operates at 13.56 MHz using ISO/IEC 14443 Type A and a 106 kbit/s data rate.

MIFARE Classic 4K magstripe cards for your setup

Check that your reader and application support Classic EV1 4K, including the required identifier format, sector layout and keys. A Classic card is not automatically interchangeable with Ultralight or DESFire. The magnetic stripe needs suitable magnetic encoding hardware; writing the RFID chip does not write the stripe.

Blank cards require enrolment or personalisation for the intended system. Contact ACB with your existing card specification before a rollout, and review the NXP Classic EV1 4K data sheet for the chip's memory and identifier options.

Write one specification for the complete card job

Use MIFARE Classic 4K magstripe cards with the identifier format, access keys and sector layout required by your application. Confirm the magnetic specification and track data independently. Printing a photograph or number on the face can support visual checking, while the two electronic interfaces serve their configured functions.

Run a sample through the actual printer, contactless reader and stripe reader before issuing a larger batch. Keep the approved supply reference for replacements. Compare Classic EV1 4K cards without a listed stripe when magnetic data is unnecessary, or assess DESFire EV2 stripe cards only against a separately approved application.

MIFARE Classic 4K magstripe cards: buying questions

Is the 4K memory all available for application data?

The nominal EEPROM includes card-management information and sector keys. Check the actual data layout rather than equating the headline memory figure with unrestricted user storage.

Can a matching frequency establish reader compatibility?

No. Confirm the supported chip family, identifier handling, key configuration and application commands. A 13.56 MHz interface alone does not approve a replacement credential.

What must the printing equipment support?

Check the physical card stock and intended print process. If encoding is part of the job, also confirm the required contactless and magnetic interfaces, software and data formats.

Check the selected quantity and specification before adding this product to your basket. For help matching a card, reader or wearing accessory to your requirements, contact ACB.
