content: Do you know about the different smart card technologies available today ?Let's leave on the side if it's contact or contactless... cpu/security or plain storage... etcMy only focus is capacity...whats the highest capacity I can have in something that looks like a credit card to the average joe?I understand it's 128KB... what do you know about this ?

content: You can use the card give the address and security credentials to access the data somewhere else.

content: thanks for the opinions...the reason I asked was because I was mentally exploring the idea of a medical card in which your medical records are not stored by your medical insurance company (which may be reluctant to share them) nor the goverment (which is the opposite... share them too much)...what if your medical records are on your own ?There's a lot of reasons why I think this is a bad idea but that doesn't prevent me from exploring this kind of ideas to check if they are really bad.anyway... does any of your countries already have electronic medical records available in any way ?

content: I don't think 1MB would be enough for much detailed information like past xrays etc which I believe are stored in most medical record systems.

content: MicroSD cards are almost as thin as credit cards. It might be possible to embed one in a carrier that is credit card sized. (Or multiple, if you really want the most storage in that form factor!)

content: The memory size you can fit in a credit card is entirely dependant on cost.Several hundred Gigabits can fit in a credit card device with released tech.Commonly/readily accessible is also a relative term and where you have placed your line.Some people can't afford their prescription costs let alone buying a card costing the same amount.For others spending $100.000USD on such a device is trivial.

content: Sorry, media is dead. That includes all storage media. Data is going into the Internet cloud so anything you develop or propose which stores data on some discrete device, disk or card is already obsolete and the people who are planning such systems are already looking well past what you are suggesting.The writing is on the wall. The only thing you'll carry is a key or ID dongle which will identify your records and allow access to them, just as credit card chip and pin authorizes purchases on your credit and debit accounts now. For me, that will be my gov't health insurance card.Most medical records are still paper based. It will be a long time before they become fully digital. There are a lot of old doctors scribbling notes in file folders even today. Mine still does. Software (people) are the bottleneck.

content: Paper records, digital imaging and an archive that has both a massive server farm and tape backups and alongside it is a set of filing cabinets with the original notes ( written in that variant of english called doctor) and printouts of the images as well. Often you get a disk with the stuff for the patient as well so that there is an off site copy in case they go to another specialist.

Even with unlimited connectivity, local storage is easily orders of magnitude faster. There are also security concerns, but good encryption fixes that.And how does the "cloud" itself store data?

content: Quote from: NiHaoMike on July 13, 2013, 02:35:34 pmDo you mean physically or logically? Physically it doesn't really matter, that's why they call it a "cloud", after the popular diagramming symbol which represents 'a thing' you don't know or don't need to know the details about. All anyone, who isn't responsible to storing them, needs to know is the API for how to access them.The actual storage of the records may not even be handled by the insurance company or government. It may be and probably is outsourced to a service provider. They may not even be stored in your country but in several data centers spread throughout the world. It's all very enterprise, big data.
