DES / 3DES (Triple DES)
Older encryption algorithms still used in some NFC chips. DES (56-bit key) is considered obsolete. Triple DES applies DES three times for effectively 112 or 168-bit security. Used in MIFARE Ultralight C and DESFire EV1.

The NFC glossary is a comprehensive reference of technical terms, acronyms, and concepts used in Near Field Communication technology. It is designed for developers, product managers, and engineers who work with NFC and need clear definitions of terms like NDEF, APDU, anti-collision, and ISO 14443.
Each glossary term is cross-referenced with related NFC chips, standards, and other terms. For example, the term 'AES-128' links to chips that support AES encryption (NTAG 424 DNA, DESFire EV2/EV3), and the term 'ISO 14443' links to all chips compliant with that standard.
Yes. NFCFYI provides glossary definitions in 15 languages including English, Korean, Japanese, Chinese, Spanish, Portuguese, Hindi, Arabic, French, Russian, German, Turkish, Vietnamese, Indonesian, and Thai. Use the language selector in the header to switch languages.
