125khz rfid tag 300,922. tuning 125 khz rfid. Yes, the frequency is generated from on the reader chip, but the coild forms a resonant circuit with a capacitor that is tuned to 125 kHz. With 5 m cable, you add at least 500 - 600 pF that detunes the circuit. For NFC payments to work, someone has to hold their mobile device or tap-to-pay card close to an NFC-enabled reader. The reader then uses NFC technology to search for and identify that payment device. Once it finds .NFC card reader Android app. Currently reads the german GeldKarte and some credit .

rewritable rfid tags
RFID Wrist Band Tags of LF 125 KHz come in packages suited for hospital patients, entertainment & guest soft silicon versions or ABS with Velcro straps for employee .
1,841. differances between 125khz rfid and 13.56mhz rfid. Hi. 1- You can send more data with more speed by 13.56 MHZ tag. 2- Antenna of 13.56 MHZ reader is smaller than 125KHZ. 3- 125 khz is better for the place which is near metal. . However 125khz tag are going to be vanished and discontinued.
As Brian mentioned, range of 125KHz RFID is limited to about 10 to 12 inches, while the range of 13.56MHz RFID is approximately 3 feet. If you need ranges greater than 3 feet you'll need to look at 433MHz VHF RFID or 915MHz UHF EPC RFID.
300,922. tuning 125 khz rfid. Yes, the frequency is generated from on the reader chip, but the coild forms a resonant circuit with a capacitor that is tuned to 125 kHz. With 5 m cable, you add at least 500 - 600 pF that detunes the circuit. That looks like it contains a multi-turn coil so the chances are it's 125KHz, the 13MHz ones have fewer turns so they don't create such a vivid silhouette. Technically, RFID is very low power so it can be used on any frequency without a license in most countries but for ease of bulk manufacturing, most are either 125KHz or 13.56MHz. 9,037. long range 125khz. For that kind of range, you would be much better off using 900 MHz RFID. A design example I have frequently described is in the attached powerpoint pdf. Note the broad band dipole design is one that I think is new and unusual. The presentation is centered around Sonnet, but most any planar EM tool can be used.
Activity points. 62,227. The 125KHz RFID transponders used in shopping stores utilize large coils on either side of an exit with lots of copper. Due to the low frequency, the size of the coils often indicates the range of detection with an RFID even with sensitive receivers. Location. Minneapolis, Minnesota, USA. Activity points. 116,648. 125 kHz has become a frequency often used for RFID. Ordinarily a long wire suspended outdoors is recommended to pick up radio broadcasts at a distance. If you're interested in RFID system, the link below relates to the same question as yours. https://electronics.stackexchange.c .
i wants to buy the rfid module of 125khz which consists of rfid reader and tag, but i dont know its no. even i dont know the production company. pls if anybody had purchased then guide me or share any link which can help me, i am usig the tags for contactless reading. i mean like it should be. Search titles and first posts only. Search titles only. By: I would like to build my own rfid reader at 125KHz. 1. Very fast oscillator start time. 2. Supply voltage low 4,5 to 4V. 3. Low antenna current because of the short comunication distanse. 4. Shut down function (very low current consumption maximum 5 microAmps) 1,841. differances between 125khz rfid and 13.56mhz rfid.
