I need an RFID transponder and controller that will beep after they're apart a certain distance (about 5 feet). I need something that will use a low amount of energy.
The limited power and processing ability of RFID chips makes them vulnerable to attackers operating at a distance. A new protocol could tackle this problem.
One drawback with RFID chips is their inability to know the distance of any device that is interrogating them. That allows a malicious user to attack from a distance, more or [...]
We are service provider for imported instruments, for which we are procuring spares and supporting the customers, all the spares are coming with RFID tag ,which we need to de-code the same. The RFID model is in the attachment. We are using this RF-ID as a serial no reader and Time counter. So, pl. let us know the possibility of using this NXP semiconductor RFID.
Hello every1.. :)
I have an FM transmitter. We can connect pen drive's, SD cards to it. Then it transmits the signals. We can adjust the transmitting signals and we should tune the same transmitting signal in the receiver.
Im currently working on a project involving my motorcycle and a RFID authentication. Since space is so limited I want to have all the controllers at the rear of the bike and have the RFID antenna at the front.
Im using Trovan RFID antenna. There are two types of antenna. 610 and 612. Actually the reader is connected to the antenna. According to trovan 612 antenna read the card tag of distance 80 cm. but my trovan antenna 612 read 40 cm, also the same problem in antenna 610 also, its read at low distance. I checked the connection b\W PCB redaer and antenna, its correct.
