RFID Reader Securely storing a small photo onto an identity card to prevent card cloning.

In areas without Internet, card cloning is a problem. NFC pass cards and similar can easily be cloned and distributed. In the absence of Internet, the small storage space of an NFC card is used to contain not only the persons details, but a low resolution photograph of the owner.

All the data is encrypted and compressed to fit on the 4k of storage on the card. The card reader presents the information (including the photograph).

The encryption uses a 256-bit message digest of the data and 3072-bit RSA keys with padding. All official estimates put this as secure (not crackable) until beyond 2038! The resulting solution works entirely offline. Stolen, cloned or lost cards now have no value. You can see the image on the card, but if you modify any part of it the card is immediately flagged as not genuine (the message digest will no longer match). A stolen card reader has no value since it only holds the public key. Only the card writer holds the private key.

Since first engaging on a project and then partnering with Gary and the FlatCoder team, the experience has been fantastic. They have not let me and my clients down once and their technical knowledge and insight has been invaluable in saving costs and time, and shortening the learning curve for the end user. Integrating data is an art they seem to have mastered and we have heavily relied on their Python skill set to develop some critical apps for clients that have saved them a lot of wasted consultancy cost. The process they have developed to take you from concept, prototype, revision, beta and final release is designed so that all parties are fully aware of what stage a build is at. Communication is first class in our experience, Gary’s personal insight into what constitutes ‘Project Creep’ has been a life safer and a profit boost in time and money. FlatCoder are our preferred partner for all our client needs and we consider Gary and his team part of the PHi-Solutions family. Highly recommended.

Gary has been invaluable in helping us set up our website and improve our SEO. Not job is too small and he works quickly and efficiently which has made the whole process much smoother than we thought it would be!

Have worked with Flatcoder on and off for nearly 10 years now, and that I keep going back for more says everything I think I need to. A highly experienced development force who can actively contribute to planning and troubleshooting, and is always willing to pull out all the stops to help get a project over the line. Highly recommended.
