MIFARE Classic 1K: The workhorse. Compatible with 90% of installed lock systems (ASSA ABLOY, Dormakaba, Onity). Proven. Cost-effective at scale. If your property runs a standard lock system with no plans to upgrade, this is your card.
DESFire EV3: The future-proof choice. AES-128 encryption. Multi-application capability (room key + loyalty + payment). Required for new Salto and ASSA ABLOY Vostio installations.
The right answer depends on your lock hardware, not the latest trend.
We manufacture both at our Shenzhen facility -- 50M+ cards per year with ex-Gemalto quality standards. Request a free comparison kit with both chip types pre-encoded for your lock system.
