| 334329 | 2005-03-15 06:37:00 | Does any one know if i can buy smartcards that i can program myself, or anything along the lines of a smart card. I thought about a USB stick, but i dont think it will work well, and it doesnt send a number, only data.... Thanks Daniel |

| 334330 | 2005-03-15 07:21:00 | Do you mean like a credit card with embedded ic? Jaycar have them zz8800,8806,8810,8820 and reader/programmers kc5361. | PaulD (232) | ||
| 334331 | 2005-03-15 08:30:00 | Just having a look, the reader/writer costs a lot, know where i can get a second hand one form? Daniel |

| 334332 | 2005-03-15 09:44:00 | What's the purpose, daniel? You might be able to find something better suited. I have a couple of eft-pos machines lying about however, one can read smart cards. How difficult would it be to interface with the reader unit? Probably not excessively hard. I'll see if I can dig them up. |

| 334333 | 2005-03-16 01:48:00 | "doesn't send a number, only data" ... ? All data are numbers; all numbers are data. Smartcards store and send only data too. Depending on what you want to do, you could use PicAxe processors as smartcards. You can make your own boards out of Veroboard, and they connect to a PC with a serial port. The PC software is free to download. The programming is easy. They have eeprom storage so don't even need to have a battery on while idle. And for a bit over $5 each for the 8M (8 pin) each the price is right. They will even play tunes. South Island Components (http://www.sicom.co.nz/) in Christchurch have good stocks. "picaxe" to Google will find you lots of information. |

| 334334 | 2005-03-16 02:02:00 | I've got a crapload of the cards somewhere..... Edit: Was it BNZ that did those Zed smart cards? They had a USB reader thing which might be useful. |

| 334335 | 2005-03-16 04:55:00 | I mainly just want to play around with the, and see how i can use them to build a secured door. I built a thing lastnight that lit up a led when a usb stick was insterted. George: Would the eftpos things be able to read the card, and then you enter a pin? Thanks Daniel |

| 334337 | 2005-03-17 01:32:00 | "eftpos things" can do all sorts of things. They are programmed. But you won't be able to access the software in them. The EFTPOS providers don't want you to know how it works, for some reason. You might be able to use the card reader socket and the keypad as raw hardware components in something you built. You will need to use a processor to handle the serial stream from the card. Any pre-used smart cards are likely to be unusable unless they are memory-only ones (and even those might be put into an erase-only mode for writing). The applications they have been used for normally don't allow the users (you) to alter the contents. That's why they are smart. ;) The Jaycar blank cards are a bit expensive, but you can write your own programmes to them. How good are you at assembly code? The PicAxe chips woule be a lot simpler. It would be easy to build one into a DB9 connector for the "key" unit. Another would happily talk to the key and operate a magnetic lock strike (through a transistor/relay or MOSfet). The PicAxe Basic code is pretty easy to use. |

| 334338 | 2005-03-17 04:11:00 | I dont know asemmbler. The reader/writer thing on jaycar costs to much (i only want it to play around with). I dont mind paying for the card, as thats cheaper. I had a look on trademe, and nothing. have made a basic thing using a usb stick, but its not quite the same ;) Daniel |
