RFID encoding
In addition to traditional graphic services, Scopus provides encoding services for a number of contactless cards, including MIFARE® Classic and DESFire® EV1, EV2, EV3.
BADGE ENCODING
Encode cards to protect and streamline access.
Encoding is the conversion of human-readable information into machine-readable information, using a system that transforms everyday data into electrical impulses: numbers, letters, fingerprint patterns…
Once converted, this data is written to a card via an electrical device.
There are several levels of encoding:
- Writing a simple number: a barcode, a number on a magnetic stripe…
- Securing data with protection keys: the case of Mifare® card read/write keys, which protect data in sectors.
Why encode?
To make the card unique (as in the case of numbering),
To protect access to the card and its data,
To set up business data (as in the case of electronic purses),
To set up personal data (as in the case of biometrics).
The different encoding methods
Factory encoding: Cards are produced with a fixed encoding.
Encoding at the card supplier: The supplier protects the cards he delivers to a customer, so that his system can guarantee their origin.
Local encoding: A system installed on the customer’s premises encodes the cards. This can be done during printing, enrolment or with a dedicated encoder.
Scopus services for badge encoding
Map use and mapping
Compliant with ISO standards: AN11004, AN10922, (standard encoding capacity and with diversified keys)
In addition to encoding (in Mérignac).
THE MIFARE®DESFire® BADGE
The DESFire® card offers 3 major advantages over previous
MIFARE® versions:
- Contactless security (EAL level 4+)
- Simplified re-appropriation of security parameters (keys),
- Easy implementation of secure multi-application cards.
- Rights management and control
- Widespread applications: Electronic purse
Access control, Coffee machine, Photocopier, …etc. - Secure communication protocol with the RFID reader
- Integrated crypto-processor for data security.
Frequently asked questions
You can get this information from your access control installer, or you’ll probably find the references on a badge box, or perhaps on an old invoice if you’ve already ordered some.
If you are unable to retrieve this information, you can send one or two active cards to our Mérignac (33) site for analysis, enabling us to check whether your badges are supplied unencoded or pre-encoded.
A badge’s CSN or UID number is like a citizen’s social security number. It’s unique, and you won’t find it on any other badge in the world.
However, UID (Unique Identifier) should not be confused with CSN (Serial Number).
The UID is the number you’ll find in a read-only 125Khz, Mifare® or DESFire® chip in Block 0 of Sector 0. This number is protected against rewriting and can be read by any reader or telephone.
The CSN is more a serial number of an application parameterized in the Mifare® or DESFire® chip, and can be read-protected by encryption.
Your systems can read this number in 4 different ways: Decimal, Reverse Decimal, Hexadecimal or Reverse Hexadecimal, truncated or not.
If we need to print it on the badge and/or provide you with a correspondence table so that you can integrate it into your software automatically, you’ll need to tell us which way it’s read on your access control software.
If you don’t have this information, you’ll need to send us 2 badges, indicating the number you read when assigning the badge to a person.
We can then send you 2 badges for you to test and report back to us. This way, you can be sure of receiving working badges on your systems.
