ePurse

The Digital Locksmiths were responsible for the development of a CEPS compatible e-Purse for the JavaCard JCOP30 platform, with bespoke extensions to support payments to be made via a pocket held in the MiFareTM space on the card. This application provides the basis for a secure, globally interoperable electronic purse programme.

We have also been responsible for the design and development of a variety of bespoke payment applications, ranging from JavaCard based e-purses to the specification of MiFare sectors to be used as storage for value. These applications provide cost-effective, entry-level solutions to a variety of payment requirements - most often for Local Authorities wanting to migrate existing services to smart card based schemes. These bespoke applications can provide a flexible approach to meeting e-purse requirements and often provide better value for money than complex e-purse implementations (which often offer unwanted, sophisticated functionality), without compromising on security.

We understand the security architectures that are fundamental to purse schemes - the implementation of the purse itself is just the tip of the iceberg.
