Resin Card 13.56MHz(HF) M1S50/NTAG213/215/216 125KHz(LH) ID/TK4100/EM4305/T5577

Description

Smart card keychain is a type of smart card that combines the functions of an ID card or M1 card with the form of a keychain. It combines identity recognition, data storage, and access/consumption card functions, and is a commonly used portable carrier for access control, attendance, community management, and other scenarios. Here is a detailed explanation about it:

1、 Core Basic Information
1. Operating frequency: M1 card operates at a standard high frequency of 13.56MHz with a typical sensing distance of 2-10CM, while ID card operates at a low frequency of 125KHz with a typical sensing distance of 2-20CM
2. High frequency mainstream chips: with M1 card (S50/S70) as the core, compatible with FM11RF08. The mainstream low-frequency chips are TK4100, EM4305, T5577.
3. Physical form: Encapsulated in ABS engineering plastic shell, with built-in induction coil and chip, matched with metal/plastic keyring, compact size (commonly about 40 × 32 × 4mm), waterproof, shockproof, dustproof, suitable for daily carrying.
4. Color and Customization: Basic colors include red, blue, black, white, yellow, etc., supporting surface silk screen printing of logos, numbers, and text, and some can be laser engraved to meet personalized and scene identification needs.

2、 Core functions and features
1. Read and write storage: The read-only low-frequency ID/EM card keychain has a storage capacity of 64 bits. The high-frequency M1 S50 has a 1024 byte storage area that supports data writing, modification, and encrypted storage. It can be bound with personal information, consumption balance, attendance permissions, and more.
2. Encryption security: The ID card number of the ID card is read-only, and the M1 card has adjustable read and write permissions to prevent copying and tampering.
3. One card adaptation: Supports compatibility with multiple scenarios, and can simultaneously achieve functions such as access control, attendance check-in, park/community consumption, elevator control, parking management, etc., realizing one card for multiple purposes.
4. Durability: The packaging process is tightly sealed, suitable for working environments ranging from -10 ℃ to+50 ℃, resistant to drop and bending, contactless induction without mechanical wear, and has a long service life.
5. Instant flash and use: No need to touch the card reader, close to the sensing area to complete recognition/reading/writing, easy to operate, fast response speed.

3、 Main application scenarios
Office scenarios: company access control, employee attendance, internal consumption (cafeteria, convenience store), conference room permission management;
Residential scenarios: community/apartment access control, unit building access control, underground garage access, property payment card;
• Public/commercial scenarios: campus access control and consumption, park one card, gym membership recognition, hotel room access control;
• Other: employee identification, exhibition visitor management, member points and consumption verification, etc.
