FREQUENTLY ASKED QUESTIONS ABOUT RFID EJS

---

RFID Jewelry Tagging

1. What is the Jewellery Tag Size ?

   Ans : They are typically small size tags in various sizes. The common size we use is 15mm x 30mm.

2. Can the tags be re-used ?

   Ans : Yes they can be reused by re-encoding the tag with new information.

3. What are the types of tags supported ?

   Our readers support several chipsets including Philips ICode, Mifare, and others adhering to ISO 15693 standards.

RFID Reader

1. What components make up a RFID reader ?

   Ans : RFID Reader is made up of a RFID reader module conected to a antenna. The antenna picks up the presence of tags and sends the information stored in the tags to the RFID reader module. The reader module then interprets the information and sends it to the calling application.

2. What is the reading distance of the reader ?

   The reading distance of a RFID system is influenced various factors. However on average the Long Range powered RFID system can read a CREDIT-CARD size tag from a distance of up to 1.5 metres.

3. Can the RFID detect tags stacked on top of each other ?

   Ans : Not Accurately. This is a typical question that arises from a typical jewelry work process. After jewelry items are made "fresh out of the oven", they are bundled together in a bag. The question often asked is if the jewelry items are poured out in a heap on to the antenna, will it work ?

   Unfortunately accuracy in detecting the tagged items falls drastically when they are stacked up on top of each other. The solution is then to alter the process to allow the items to be arranged in a tray before scanning OR manually spread the items evenly on the antenna before scanning.

   The point is the little effort invested to slightly alter the process for RFID to work, reaps heaps of financial benefits later down the supply chain.

4. How many antennas can I connect to a RFID reader ?

   Ans : You can connect 1 antenna per RFID Reader Module. However you can use a MUX ( multiplexer ) to connect up to 4 antennas to one RFID Reader module.

5. I have X amount of showcase / shelf space, how many readers do I need ?

   Ans : It is often difficult to guage the size of a RFID setup just by citing the number of shelves available etc. RFID implementations in jewelry stores are influenced by both environmental, automation requirements, budget factors.
