Sir,
We would like to discuss on the report “Micro secure digital card.”[1] Colvenkar and Gopal noted that “the proposed method is simple, cheap, and can store large amount of information.”[1] Of interest is the fact that though there is no doubt about micro secure digital card being a cheap method, the question left is on its cost-effectiveness. A comparative study on the efficacy of the new micro secure digital card to other classical techniques should be carried out. Also, as a digital card, the security has to be further approved. Although it is mentioned as a secure digital card, the problem of data protection and privacy as well as skimming are also big concerns.[2] Finally, since the denture identification has to be kept for a long term, the durability check for only a short period in the present study carried out by Colvenkar and Gopal[1] might not be sufficient.
