For example, the manufacturer can implement high-level APIs and allow the user to write custom applications for the card reader. This can be facilitated in multiple ways. Therefore, having the capability to load custom keys by someone other than the card reader manufacturer becomes essential. In many instances, the end-users have their own customized cryptographic keys for their credentials and are unwilling to share these keys with the card reader provider.

The best card reader is one that can not only decrypt the memory segments and access the data but also provides an easy means for the end-user to carry out this operation themselves. Many types of contactless RFID transponders have the ability to store data within their memory segments and encrypt or lock these segments with cryptographic keys. Then, you need to make sure the reader you select has the capability to support the encryption you need and to execute cryptographic algorithms. It is important to first analyze where exactly in your architecture the encryption is required and then to establish the strength of this security. In some cases, data must be encrypted at both interfaces. For example, you may require encryption of data exchanged between the reader and the host system or via the air interface between the RFID reader and the card or device.

When you are planning to implement RFID technologies to exchange or store information, you must first assess the level of encryption required by your application and the exact channel where this needs to be enforced.
