How to use this kind of rfid reader?

How to use this kind of rfid reader?

How to use this kind of rfid reader?

(OP)
Hi everyone… my application use an rfid reader for input in the texbox… it works fine… i tried buying this rfid and qr reader, it doesnt work, theres no input when rfid is tap on the device… is there soemthing i missed? Please help…

RE: How to use this kind of rfid reader?

What is the driver, and how is the call made to the reader? (Or, how is the reader referenced in code?)

RE: How to use this kind of rfid reader?

Mandy,
first of all, provide a page of the vendor and device name. The caption on the backside turns out to be that device, but could also just have been the product code of the case used in that scanner device. Mandy, as always, please provide more information.

Is it this? https://www.sycreader.com/en/3650/

Then you already find some restrictions of what it reads: EM card or Mifare card. Not just any RFID. Also, it's mainly a QR code reader by product name. I didn't dive into more details, but I think you just expect too much of its RFID capabilities, that's all there is to it.

Chriss

RE: How to use this kind of rfid reader?

Mandy,

Even though I have C# application to deal with RFID, I am not sure if an RFID reader can act as a plug an play device, ie just like a barcode reader. As Scott asked, how you're connecting to the RFID reader? You must have received an SDK for the device, isn't it? It must have its own documentation. Which brand/model it is?

Rajesh

RE: How to use this kind of rfid reader?

Mandy,

As Chriss mentioned, you have to see what all thigs it can read.

I found a PDF documentation https://www.sycreader.com/wp-content/uploads/2022/...
I believe this is the one you have.
Please check this to see if it can read what you're expecting it to.

In the documentation, you will find there are settings to turn on/off what it can read.
To set it, you have to scan the corresponding QR code from the documentation.
Just play with it to have various settings and to see the differences in its functioning.

RE: How to use this kind of rfid reader?

Good reference, even if it's not very informative, it lacks more detailed explanations of the modes it allows. I'm also not sure if it's a R35 or R36, both product numbers exist. The reference to what kind of RFIDs it can read is pointing out smartcards, and so its intent is rather person identification as in an attendance system, than it would be scanning products of a cart in a POS system.

There are very different RFIDs, in cards like smart cards or banking cards, and credit cards, but also in tags that can be put on products. They work in very different frequency ranges and some are passive, some active. If your customer already has chosen a certain tag type to put on his products, then you have to also use a matching device, there is no "one size fits all" device as it's with optical scanning of line barcodes or QR codes, your reader has to match the frequency range of your RFIDs or vice versa and active or passive also doubles the possibilities and necessary device capabilities. So there is no such thing as an "all RFID" reader. If a device can scan all RFIDs on the market, then it's a combination of at least 3 readers, as far as I see it. So look out what exactly you have and thus what you need as a compatible supplement, also regarding what interface you're willing to implement.

The short reference paper Rajesh finds for the R35 device is specifying different COM port settings. That indicates the device also works as a serial COM port device and sends in it's scanned data to a COM port. If there is no software listening on ports nothing is received. In that case you would need to do COM port programming, Mandy.

The manual also has a line stating the communication methods available:

Quote:

communication method: Wiegand/USB/RS232/TCP-IP/RS485
Which includes TCP-IP network communication. This short reference manual doesn't tell though, how it is accessible as a network device or at which port to listen to incoming network packets. I would look out for a better documented device, if that's all the documentation you get for it. I'll hope it came with a manual richer in informations.

RE: How to use this kind of rfid reader?

Thank you rajesh... but even if its connected to usb, it when rfid is tapped nothing happens, there no input... the code at the back seems not the code for the rfid reader to work...

Chriss... my application works with rfid reader but not to this reader... i tried reading the manual sent by jesh, but there is not instruction on how to use it... or may be i just dont understand it... but now still im trying to let it work... best regards to everyone...

RE: How to use this kind of rfid reader?

Mandy,

I just visited below page in their website.
https://www.sycreader.com/en/3624/
But there is no SDK or elaborated programming example documentation. The one they have is the same we shared here above.

Then I saw this page:
https://www.sycreader.com/en/services-support/sdk/

The first link says 'SDK + Demo'. So, I hope you must get the complete SDK files, documentation and a demo application showcasing the SDK's implementation. This should help you I believe. I have not downloaded and tried it.

Rajesh

Yes, I already was telling the documentation is bad.

There are some QR codes in it though, and Rajesh said:

Quote (Rajesh)

you have to scan the corresponding QR code from the documentation.

Maybe it will work to use the QR code that says "USB HID keyboard". Do you remember an older thread of you, where you were explained what HID means? And keyboard is speaking, isn't it. I would assume that QR code sets that devvice in a mode it otputs what it scans as keyboard input. Then just opening notepad and scanning RFIDs should make them visible.

But ONLY, and that's a big only, if your scanner is a R35-QR-Reader. It looks very similar, but so does the R36-QR Reader. Mandy, I aksed you which scanner you have. The models and makes differ and you can only use the manual and divers for your specific QR/RFID reader. The first thing to know and tell is is exactly what reader you have. I'm really disappointed.

Chriss

RE: How to use this kind of rfid reader?

>which scanner you have

If the photos are an accurate representation of what the OP has, then this is the R35 model

RE: How to use this kind of rfid reader?

Mandy,

just to point it out once more: You have many options more than just providing an image of your reader, to tell us which reader it is. If you ordered it the product name will be on the invoice and delivery slip. The manual that came with the device would have the product name, the device manager of Windows will list this scanner and you can see the vendor aand product name there, too.

Please, provide that product name. usually, when you know the exact brand, model, product name of something you find the vendor support homepage, driver,s manuals etc. online. Even in a situation, you are just given this b your customer and they didn't keep the manual, you have dozens of ways to find out what this scanner is.

Notice what I said already, it can make a huge difference on how this reader has to be configured if it's an R35 or R36, if it even is one of them and not another model. We can't know this for sure. But you can find this out. First thing to find out is that. And then you can find the correct manual and drivers or SDK for it.

Chriss

RE: How to use this kind of rfid reader?

Strongm. I read R35 or R36 from the image. It's not really sharp.

Chriss

RE: How to use this kind of rfid reader?

The other identifier (20190416084) is sharper, and you can ID it from that.

(Also, the pictures of the R36 on the Sycreader website differ from the ones in the original post, whilst those for the R35 are an exact match ...)

RE: How to use this kind of rfid reader?

Mandy,
Have you proved whether this device works in any capacity at all?
Is there a sample application or hardware setup that allows you to validate that the hardware is attached correctly and functioning as it should?
Do you have more than one device to test with?
Otherwise, this could simply be a hardware problem that no amount of programming will resolve.

RE: How to use this kind of rfid reader?

> if its connected to usb, it when rfid is tapped nothing happens

You need to configure it using the QR codes as per the PDF documentation linked to by Rajesh Karunakaran earlier. It seems to have two USB modes, HID keyboard and virtual serial port. Sounds like what you want is the HID keyboard. So just scan the USB HID keyboard QR code. And then wave one of the supported cards (EM or Mifare at 125Khz or 13.56MHz) and, all being well you should see characters appearing on the USB.

RE: How to use this kind of rfid reader?

(OP)
Hi everyone thank you for all your answers... it took time really to digest all the information you have given... and i guess i cant make the reader working with my vfp aplication....Thank you Chriss...

strongm yes i need to configure the reader but in the demo there is java, vb, c# etc.. but there is no VFP... Thanks strongm and rejesh....

scott... its working in another program not done with VFP.

RE: How to use this kind of rfid reader?

You're still evading questions and advice, Mandy. I don't know what to do but point the two most important things out once more:

1. Question: What is the model of your reader. Is it an R35 or R36 or something else?
2. Have you tried to scan this QR code from Rajeshs reference?


If your device is an R35 reader, this should configure it to output the RFID data as keyboard input. If you then open up notepad and scan an RFID this should display in notepad.

Chriss

RE: How to use this kind of rfid reader?

(OP)
Hi Chriss.... I really dont what is the model, but the lick sent by rajesh i believe is...
Yes Chris i tried advise by Rajesh, but nothing seems to work, i even tried opening notepad and tap just like i did with the old rfid reader i have, but nothing appears, it just beeps long that it will never stop until i remove its usb cable... Thank You Chriss

First, you have to set it up to work as a keyboard. and you do it in that model by scanning that QR code. With the reader, of course.

Quote (Mandy)

I really dont what is the model
How is that possible, that you have a device and not know its vendor, brand, make, model, or product code?
Do you have anything but the device itself? A CD? A manual?
Is the photo you posted just vaguely looking like it or is it from the manual, from the website you bought it from or what? Please, explain that, Mandy.

Chriss

RE: How to use this kind of rfid reader?

(OP)
Hi Chriss sorry to confuse you... Actually that rfid reader is also used in my work, but the language use is postgresSql.. It can qr code and rfid to, but when i tried it with my application, it did not work, I just wonder that it doest work with my program done in vfp thats why i ask it here... Thanks chriss

RE: How to use this kind of rfid reader?

I don't know what kind of attachments you tried to add to your post, but it didn't work. And postgreSQL is a database, not an rfid reader.

We just need the product name to find the necessary reference material. You still seem to think it doesn't matter and all readers work the same. Notice: No, they don't. Only knownig what reader you have you can find out how to use it, how to address it with software or how to configure it so it acts like keyboard input.

As long as you don't know that, the easiest solution is to actually buy another model. One, of which you then know what it is exactly, one that will then be available with manual and drivers on C or anything like that. You could even pick one that by default acts as a keyboard if that's the only thing you can work with.

You can wait forever for it to explain itself to you by its beeping, and we even will be less able to help you with it.

Chriss

RE: How to use this kind of rfid reader?

Mandy,

Another thought on this!
Few more things to check.

Quote (Mandy)

but when i tried it with my application, it did not work

Is the other application run in another computer?

Usually, Rfid reader manufactureres provide their DLL also. Please check if there is such a file in the other computer where you say the reader is working.
Copy that DLL in the application folder of your pc. Register the DLL (usually this is required). Maybe, a PC restart is required (I am not sure).
Then plug in your reader and try again.

Also, check with one of the cards which works on the another computer.
Sometimes, the reader might have been configured to read only certain frequency ranges.
So, check the card which doesn't work in your pc on the other computer to verify if it works there.
