RFID tag for communication with u2270b

cheapest rfid reader ic

Id like to program the u2270 with a wireless keypad using a transponder. Atmel has the u3280/u9280, but sells it in large quantities. Any alternative idea?
 

ti rfid circuit

I have tried the U2270 but it does not really have good range. The problem is that it requires a sqare wave detect input. The ID2/ID12 series are much better as they are smarter and require an analogue input. The analog input is digitised and processed. Vibration and noise effects are reduced and the range is much more. With an ID2 and an external antenna I have read ISO cards at over 40cms!!! Some geeks report even more but I suspect they are driving the ID2 too hard. Another important aspect is the ID2 will accept a high Q antenna - try that on a U2270, the recommend Q is 10, give it a Q of 100 and it will stop reading completely. The see ID series are advertised at Mannings, Tectus, Adilam and a few other places. Oh yes, and the ID2 only requires an antenna and 5v. The ID12 has a biult in antenna. Makes life easy.

Hey
Somebody please tell me where can I get any of these chips in India. Thanks in advance
 

sonmicro rfid reader schematics download

Hello Luben111,

Thanks for the schematic and everything. I want to modify the circuit. I need to read the tag id from the reader from my computer through the serial port. Is it possible to do so? Is there any source code or the way to decode the transpoder? Please help me. Thanks!!

u2270b schematic

Hello.
I have a problem with U2270B and EM-4001 transporder.
Antena I have L=627uH. And build other shematic, work but I don`t have good card code.
In Em-4001 the first 9 - bits is 1, I have this bits but last bits is not good.
In pin U2270 - Output a have f = 0.4~2.4Hz when put card f = 1.54~1.65;
In coil f = 122.5Khz. Use 220nF and 1.5 nf for pin HIPASS,Input.
For decode I use AVR .
Can you help me.
 

rfid reader electronic scheme

Hi all

I will design a wiegand reader, how can i design the output stage of the wiegand reader. Is there any sample schematic ?

thanks
 

rfid reader on avr

we use U2270B too
 

rfid reader u2270

if some one can help me to find cheaper ID-12 or subtitute (same function and same pin)?send e-mail to:s14016au@yahoo.com
 

u3280 antenna

Maybe this question sounds dumb, but Where do I found an antenna of 1.35mh or How do i made it?
 

rfid tag schematic

can anyone email me the files transponder.zip and trans628 shematic.pdf. This files are not available on the groups

Thanks in advance
 

ic used in rfid readers

you anyone email me transponder.zip posted by luben111 cos I do not have access to zip files at my place.

thanks in advance
 

rf reader ic

Hi there!luben nice job!

Though can anyone tell me ,the data comunication between the U2270 and eg the Atmel's TK5551 is sequential or Half Duplex?Could someone explain me step by step ?

Thanx in advance!!!

3515 rfid circuit

This website offers plans/schematics/Bill of Material/Code/etc for building an RFID Door Lock and Monitoring System. Once built a user can monitor their front door from anywhere in the world. The reading range is 15-20 cm without the amplifier circuit. This project utilizes the TI S6700 Multi-protocol IC. The code for communicating with a 13.56 MHz ISO15693 card is available. Check it out.

id2 rfid schematic

Hello, I.m designing a rfid sytem and now I´m designing the reader`s antenna.
I`m using a sokymat unique tag for 125 khz. But I need some information of the tag´s antenna to maximize the read range.
Where can I get the information about the antenna of this tag???
