Magnetic Stripe Cards
-
Depending of the magnitude of the project, it might be worth the costs, but to small budget projects, this might be a constraint. Of course, it all depends of the use. Some readers (like anttenas) are very expensive, others (like handhelds) are still expensive, but not that much. And there are the lower cost readers (small close range with no interface devices). But all of them are more expensive than magnetic readers. Again, all depends on the needs. RFID could be a solution, but it rarely is for small budget projects. It is usually not worth the extra costs. But a study needs to be made prior to taking such a decision. Also, I've not seen any RFID writers at a reasonable cost. Regards, Fábio
Hey RFID is perfect for this application. You don't really need Mag stripes as you don't need to write anything to the card - all you need is a unique ID to attach to the garments. The RFIDs are very reliable in the wash and they come in key-fob format which might just be perfect. As for cost - they may be a little more but think of the application. Having to swipe each card will be a pain for your users as opposed to just waving the tag over the reader (or the reader over the tag). And you don't really need a writer, just a reader to read that unique ID to attach to your customer in the database. This means you can get the older, cheaper 125Khz tags and a simple reader. The key question here may just be how many tags you need? I suggest you go here http://www.stronglink.cn/english/sl102.htm[^] and get a reader for $21USD and a bunch of tags for 40 cents each (much cheaper if you buy bulk, as little as 28 cents). Shipping and customs duty on top of that.

It is expensive, beleive me. The RFID tags are not expensive. Expensive are the readers an writers. And they are very expensive.
I don't think they're that expensive as most of people thinks... You may want to visit sparkfun.com and check under the sensors -> ID section (on the left pannel)... You can get an RF-ID Reader Module (like ID-2, ID-12 or ID-20) between 25-35$ and the fancy USB interface for PC for only 25$... The magnet card reader costs 60$ and the reader/writer costs 140$... You don't need a writer for RF-ID tags, they're pre-programmed with an unique ID... These modules (ID-x, the differences are internal/external antenna and range) are very very very extremadely easy to use with microcontrollers!... They only need power supply (Vcc and Ground connections, 5V I believe, I don't remember) and they just "spit" a TTL UART-like (RS232 compatible with an MAX232 chip) stream with the code of the card you just approached to it (they also have some Wiegand and whatever compatibility mode) and the microcontroller might read it using HW or SW UART... It takes about 5 lines of code in a microcontroller (exagerating a little, of course) to do this task... If you are not messing with microcontrollers, you can get the USB interface in which you might plug in one of these modules (I can't give you further details on this because I haven't used it, only the modules)... Anyway, I don't think you'll use a PC to control all the distributed readers in the laundry, will you??? :~ All the detailed info (datasheets, etc) is on the web site mentioned before... Hope this helps!!! Cheers!!!

I agree with Stephen J Chin and dmpthekiller. We bought some readers and rfid cards for a project we did a while back and it's really not expensive. You don't need a writer, the cards come with a unique id which you associate with the user in your database. We got our cards here: http://www.futurlec.com/LF\_Cards.shtml Our application was a timeclock application so we got the timeclock elsewhere, they were also fairly cheap, around $100 (had buttons for clocking in and out and to enter passwords and a fingerprint reader as well as rfid).

Just an idea, but wouldn't it be better to use an RFID based card instead of a magnetic card? They seem much easier to use, and are more durable (not erased by magnets), but I have no idea about the cost difference. (edit) http://www.rfid.org/[^] has links to RFID equipment suppliers.
How about barcodes?

RFID: Not expensive. No writer required. RFID come pre-programmed. http://www.phidgets.com/products.php?category=14&product_id=1023

Hi, Does anyone know where to get Magnetic Stripe Cards, Card Embossing, Card Readers, Pin Terminals etc. for legitimate reasons. When googeling, I am burried with links to Hacker sites, trying to sell all sorts of items to forge Credit Cards. I am developing a Software Package for Laundrettes and Drycleaners based in the UK and Ireland, a Swipecard would be the logical successor to a Laundry Ticket.

We've done work with Smart Cards in the past. We worked with a company called Debitek that was, at the time, owned by Ingenico. Ingenico is pretty big in Europe I believe so you can check them out. Smart Cards are more expensive than magstripe, but can also hold a lot more data and are more secure. However, it doesn't sound like you'd need that for your solution. As other replies have suggested, MagTek is one of the most well known leaders in this area and we've implemented their magstripe hardware products in the past. I would be interested in talking with you about your solution as we have done a lot of work in this area. Please contact me privately if you'd like to discuss further. Cheers, Chris

Ran across this recently.. $50 for 10 tags plus a USB RFID reader. Additional tags look to be about $1 each. http://store.touchatag.com/acatalog/touchatag.html Even Amazon sells these starter kits. Looks like a fun thing to play with, wish I had the time.

Well, I guess that depends on where you are. Here in brazil they are pretty expensive. Magnetic cards here are always cheaper. And yes, if there is no need to write to a tag, I guess that would be a good choice.

Hi, There is a company called MagTek that produces them, they have a website and if you emailed them they can probably provide you the details of a local reseller in your area... either that, or you might be able to buy on line. I think the 'Cherry' range of keyboards also has some models that have card readers built in. Unfortunately I don't know where you get the cards themselves from, but again one of those manufacturers may be able to help with that.

www.evolis.com We used the Dualys for while, but most of our customers tend to prefer to use barcodes on the card rather than mag-swipe as its slightly cheaper per card, and they already have barcode scanners. All fairly simple to drive, blank cards ribbons etc reasonably priced.
