It can store any information you wish in encrypted form on your computer, which then very simply synchronises with your phone. I use to remember bank accounts, credit card numbers, memership numbers, etc. Superb!

I also put in numbers I may need for short-term situations, and remove them afterwards – hotel, shuttle and taxi in destination cities when I’m traveling, for example, listed by city or event name so they’re all grouped together.

One of the security tips the agents told me was to NOT store my passwords/sensitive data on my cell phone.

I have a 4 digit “code” that I use to encrypt my pin numbers. I use something simple, like add the number to my code to equal the pin, either using individual numbers or the whole pin (if my code is 1234 and the number on the card is 2345 then my pin could be 3579). You could also use a subtractive method. Whatever method you use I’d be consistent.

As a plus…if the idiot who tries to use your card in an ATM gets the code wrong too many times, which he’s bound to do, the card will get sucked into the machine.

@Celeste – That’s a great idea! I wish I would have seen it sooner!

@Lucas – These days phone = wallet. I’ve got a little thin leather thing that I always keep in my pocket with my phone. I think that thing is where cash used to go, whatever that is. Now it holds my check cards and drivers license. I suppose if your phone gets stolen you’re screwed. Just like if you lose your wallet.

I use an app called SplashId for my PDA. It’s not the best password manager for a PDA, I prefer KeePass but either work great. They encrypt passwords, id’s, and credit card numbers and store them in a secure way so that you always have em with you.

In fact, memorize your pediatrician’s phone number. You’ll be glad you did.

I actually also store credit card details in case I do not have my wallet on me and need to use it for online purchases – I keep those in password protected application called Mobile Secretary – unfortunately not a freeware but not expensive, simple and nice. It can be also used for user accounts, passwords, PIN codes, etc.

@Charlene–don’t schools still use a student’s SSN as their ID#? Doesn’t seem like this would be a smart number to keep in your phone.

One of those small wallet photo books would work, too!

Camera phones you might be able to do this with if you can get them the right size and a good quality image. The ones I’m thinking of wouldn’t matter so much if my phone was stolen … Library (when they issue a new number the old one is inactive so someone couldn’t steal a bunch of books in my name), grocery store, CVS … and all of these other “customer discount” cards.

Ooo that reminds me, I need to go get something … I’m going to see if I can get their barcode in my phone see if it will work.

I just use a very low tech version. LOL! I took all of my cards and put them together with a single hole punch and then placed them on a large round circular ring that you get at the office supply store.

On my errand day, I take the ring with me. When I get to the cash register, I just give them the card. That way, the cards don’t clog up my wallet. You could keep the ring in your car too so you only have to grab it when you go inside to the store.
