There are several ways to reach the next level of safety application on RFID chip card-based security with MIFARE plus RFID technology to high security for your own. Often companies but tackle a migration from old RFID chip card to the new generations of highly secure, because they fear the high cost and hassle of handling are shying away from. This classic-based migration of MIFARE systems to the new highly secure MIFARE plus card very easily and affordably possible. The benefits of the new RFID chip families are obvious: after it was made public that the then-current chip generations MIFARE Prime were classic and cracked LEGIC, manufacturers have responded with new generations of RFID chips that work with highly secure AES and 3DES encryption crypto. These offer a great protection against data theft and tampering attempts.
The MIFARE plus chips are available in three levels of security, the migration to a higher level is very easy and can be done directly through the appropriate reader. New cards are not necessary for the migration, because the chips are encoded simply by the reader and from this point provide the higher security encryption. Applications which were established based on MIFARE classic smart cards can be upgraded gradually and without high costs on the new MIFARE plus technology. Failures of the system can be avoided this completely. The flow of migration can be represented as follows: in a system that is based on plastic cards with MIFARE classic chips, a switch should be on a higher level of security. MIFARE plus smart cards should be used for this purpose. As a first step, only MIFARE plus cards are issued from the date of the decision as a new card. This is entirely unproblematic for the reader in use since the MIFARE plus chips 100 percent are backward compatible to the MIFARE classic cards and hence the corresponding readers without problems recognized and read by be can.
The old MIFARE classic cards can initially still remain in circulation and step by step MIFARE plus cards be replaced by, unless a system failure in purchase must be included. The card reader can also gradually replaced and used later for the upgrade of the MIFARE plus with security level 1 security level 2 or 3. The test phase of the MIFARE plus in level 2 or 3 runs successfully, after all MIFARE plus cards with level 1 by the reader on a higher cannot be migrated security level. Thus, non-contact safety at the highest level without much effort and cost will be available.
