i am interest to buy this project set, but why i cant add into a cart? how?
can i use this project set to store the point as a loyalty program after i used the RFID card to login as member?

hi,

probably because the stock status =0;


regards,
yh

You send email to sales of Cytron, not at technical forum.
Anyway I think you should check the stock status as yonghui said. If the stock is 0, how can you buy?

Not really understand your question on loyalty program and use RFID card to login as member? I really like to see what you really mean.

actually loyalty program is work as reward system. After system accumulate the points, it will auto store that points to card while the user use card to login as member. Example like member for supermarket or some shop. U get what i means?
So isn't this card reader can functions to store the points to card?

robosang and yonghui is right, if the stock status is 0, you cannot add to cart as there is no stock available to send to you.

PR25 is a DIY (Do It Yourself) project showing the operation of RFID reader, and combination of PIC microcontroller. I will not say is a complete working product, it is more for educational and learning purpose. You are free to modify the source code or even modify the circuit to become your own project.

The RFID reader read ID from passive RFID tag. Every tag come with 10 digit unique ID. Of course you can program the PIC and hook up to computer, further develop the software and database to record the loyalty points.

The RFID reader reads the ID and transmit it out to host (in this case is microcontroller), that's all. You will need to further develop the point accumulation, calculation, rewards, database.....etc.

azlan.k WROTE:i have buy reader from you and build this PR25. but i found out reader that i buy need 12v to working it work but when i connect with em lock, the board hang. what your suggestion to solve this problem?

Without looking at your schematics. I'd suspect 3 things:

1. Your 12V power is under-rated.
2. You didnt put a diode across the em lock coil.
3. The capacitor uF across the 12V supply is too small.

There maybe some other problems that I didnt know.

Allen

Agreed with Allen, most probably is 12V is not sufficient to power the magnetic load. The current not enough, voltage drop, PIC not working, nothing works

i would like to ask, i used keychain tag for this project and i already burn the source code of PR25 into PIC16F876A. why is the circuit still can't function eventhough, the circuit is all complete? is this because of the PIC ? or the program? and how to insert keychain tag id into the program?

You build your own circuit? Or you bought the whole kit from Cytron and solder it up? I think even user uses the kit from Cytron, there's possibility that his soldering has problem and causes connection break. Try check your circuit again?

i already check but still cannot function.. there have some problem with this programme???
