Frequently asked questions
Does a more sensitive chip guarantee a longer read range?
No. Datasheet sensitivity is a bare-chip value. The antenna design, tagged material, reader antenna and power determine the performance of the complete label.
Which memory capacity should I select?
Start with the identifier and application data your system needs to store. Check the actual chip record: EPC, user memory and TID are different memory regions.
Can a chip be changed without changing the antenna?
Some designs list several chip options. Ask us to confirm the chip and antenna pairing and validate samples before replacing a previously qualified configuration.
