RFID Rewritable 125KHz/13.56MHz ID/IC T5577/UID Changeable Black Ceramics Smart Finger Ring for Men or Women, with One RFID Reader Copier for Duplicate (Black 125khz 19mm)

Product details Chip: T5577/UID Changeable Mode: ID/IC Frequency: 125KHz or 13.56MHz Inner diameter of ring: 17mm, 18mm, 19mm, 20mm, 21mm, 22mm Color: Black Material: Zirconia Cormic + Epoxy Resin Sensing direction: Omnidirectional sensing Sensing distance: 0-10cm (Depends on reader) Packaging: One Ring + One Copier Note: 1.Before you buy the ring, please make sure the frequency. We have two kinds: ID 125KHz T5577 (Copy EM4100/EM4200/TK4100/Proximity II card) IC 13.56MHz UID Changeable (Copy F08/Classic 1K S50 card) 2.When use ring to copy card, please make sure if the card you want to copy is encrypted. If the card is encrypted, then the ring can not be copied by our copier, unless you have other copier that can decode. 3.Some access machine work with encrypted card, our ring can not work even the frequency and protocol is compatible. At this situation, you should ask the reader supplier to authorize the ring. 4.Our ID 125KHz ring is blank, it can not be directly used for access reader or lock if without copied and written(We offer a coin card to copy). Our IC 13.56Mhz ring can be directly used with access control reader or lock, the UID (Sector0 Block0) is pre-programmed. It can be rewrite, once rewrite the old UID will be automaticly covered.

• ID 125KHz ring In-built with copyable T5577 chip, can copy the tag like TK4100/EM4100/EM4200.
• ID 125KHz ring is blank ring, it can not directly used for 125KHz access reader or 125KHz lock without copied or written. If you want to directly used for your lock or reader, you can use the copier to copy the coin card to ring, then the ring will has a UID to work.
• The ring comes with a 125KHz copier, allow you to copy your old 125KHz card to the ring. But it does not support to copy encrypted card like hotel card, bus card, credit card, ect...It also does not support NFC function.
• Our RFID ring uses 360-degree omni-directional sensing technology, the sensing effect is much higher than similar products in the market.
• Our RFID ring is made of zirconia ceramic material, which is very comfortable to wear.
