Why RFID Keyfobs Are Replacing Traditional Keys?
RFID keyfobs replace traditional keys with enhanced security, convenience, and custom designs for smarter, modern access control solutions.
Когда дело доходит до RFID (radio frequency identification), everyone has heard of it more or less. And NFC (near field communication) is actually a derivative technology based on RFID. Although many people often confuse the two concepts, in simple terms, NFC is like the “close-range communication expert” in the RFID family.
In RFID technology, the derived products are mainly divided into three categories:
Passive RFID products
Active RFID products
Semi-active RFID products
According to the working mode of RFID tags (Tags), they can be further divided into пассивный, активный, и semi-active. Among them, the most common are пассивный products.
We are most exposed to this type of product in daily life, and the MIFARE Classic 1K card (also called M1 card или S50 card) is one of the representatives.
Flexible partitioning: Data can be classified and stored according to different needs, such as access control permissions, consumption records, identity recognition, etc.
UID unique number: Each card has a unique global UID (manufacturer segment), which cannot be changed, improving the security and identification accuracy of the system.
| Функции | Parameters |
|---|---|
| Storage capacity | 1KB (16 sectors, 4 blocks per sector, 16 bytes per block) |
| Частота | 13.56МГц |
| Working mode | Пассивный |
| Data protection | Key A/Key B password can be set for each sector |
| УИД | Globally unique and cannot be copied |
Each sector is equipped with an independent password system (KeyA/KeyB).
The password is combined with access control permissions to set which content can be read, written, or not operated.
The data has strong anti-tampering и anti-copying capabilities, suitable for application scenarios with high data security requirements.
Follows the ИСО/МЭК 14443А standard and is compatible with most 13.56MHz read-write devices on the market.
Contactless reading and writing can be achieved without dedicated hardware, which is convenient for rapid deployment and integrated use.
MIFARE 1K Cards are widely used in the following scenarios:
Access control card: Write access control permissions, swipe the card to enter.
Consumption card: Such as campus cards, canteen cards, store balance and consumption records.
Transportation card: Swipe the card to pass through subway and bus systems.
Others: Hotel room cards, membership cards, social media business cards, etc.
Contactless operation: Just approach the card reader to complete the operation—simple and convenient.
Long service life: No built-in battery. The service life can generally reach 10 years, supports 100 000 раз of erasure, and the number of reads is almost unlimited.
