Card SN
Each iCLASS contactless smart card has a unique serial number. When you press the Get Card Cfg
button, this number is retrieved.
Card Context
This section describes the area of memory on the card you intend to work with along with the specific
key location (1-7) in the reader that will be used to attempt to gain access. See Memory Map above for
additional details.
Key Management
In order to successfully read or write to an iCLASS card the correct security key must be written to the
reader. If the key being used in the reader does not agree with the key in the card (for the area of the
card you are trying to work with), you will not be allowed access.
The reader is capable of holding up to 7 keys, although one of these areas is used by the system as a
key swap area. You may write either default keys or specify your own keys and write these to any of the
reader key locations (1-7). We caution you using location 7 as this is used by the reader internally as a
swap register. As mentioned above, please write an invalid key back to the location once you are
finished with the memory operation so as not to leave an access key for someone else to use.
New Key (ASCII)
Enter a new Key in this field that you will send to either the card, reader, or both. Pressing either the
Write Key to Card
or
Write Key to Reader
will cause this key to be sent to the corresponding unit.
Key in Hex
The value entered above will be converted to hex and shown in the
Key in Hex
field.
Write to Card
Writes the New Key (ASCII) value to the iCLASS contactless smart card.
Write to Reader
Writes the New Key (ASCII) value to the AIR ID reader.
Write Default to Reader
Write the default key value to the AIR ID reader.
Read / Write
This section of the screen works with the read/write portion of the iCLASS contactless smartcard’s
storage area. There are three different iCLASS cards:
1. 2k
2 Application areas
2. 16k
2 Application areas
3. 16k
16 Application areas
The memory size and partitions are different for each of the card style.
To familiarize you with the memory organization, please see the Memory Map above, or on the Memory

The following six items are grouped together as they deal with read or writing a specific number of
blocks in the cards memory space.
