Applications for MIFARE® Classic 1K Cards
Access Control
Secure office buildings, healthcare facilities, schools, warehouses, and restricted areas using reliable MIFARE® smart card technology.
Transportation
Ideal for transit systems, airline ticketing, parking access, tolling systems, and park & ride programs requiring fast contactless transactions.
Temporary Employees
The clamshell style MIFARE® card is rugged and ideal for temporary or contracted visitors. Utilize adhesive-backed PVC cards to easily add a photo ID.
Loyalty Programs
Efficiently store and manage customer identification data, membership credentials, account balances, access privileges, and other application-specific information within compatible smart card systems and RFID infrastructures.
Professional CR80 Format
Built to standard CR80 credit card dimensions, the MIFARE® Classic 1K Clamshell Card can be imprinted with your logo or other graphics via our LogoPROX® branding service. Custom branded smart cards help strengthen visual identity and increase brand awareness by incorporating company logos, school graphics, membership designs, or organizational colors directly onto the credential surface for a more professional and recognizable appearance.
Expandable Hybrid Card Capabilities
For organizations requiring broader system compatibility, these cards may also be enhanced with embedded contact smart chip modules or magnetic stripe technology. This flexibility allows one credential to support multiple technologies simultaneously for migration projects, hybrid environments, and multi-system credential deployments.
Frequently Asked Questions About UID, CSN and Serial Numbers
Is the UID the same as the CSN?
In many access control systems, yes. CSN commonly refers to the card’s UID. However, the number may be displayed differently depending on reader output, software settings, decimal conversion, or byte order.
Is the printed number on the card the same as the UID?
Not always. The printed number may be a visual card number, inventory number, or programmed credential number. It should not automatically be assumed to match the chip UID or CSN.
How many bits is a MIFARE® Classic 1K S50 UID?
A traditional MIFARE® Classic 1K S50 card commonly uses a 4-byte UID, which equals 32 bits. Some variants or compatible chip types may use longer UID lengths, so the exact specification should be verified when matching credentials to a system.
Why does the same card show a different number on another reader?
Different readers and access control platforms may convert, reverse, truncate, or format the UID/CSN differently. This is a common reason the same MIFARE® card may appear differently across systems.
