The W7001 is a small flexible Near Field Communication (NFC)
antenna ideal for embedded products such as tablets, laptops, and
payment terminal devices. It is intended for both secure payment or
security access applications.
The W7001 is a thin, flexible antenna that can be fed with customer-
supplied spring clips, contacts, direct-solder methods or with the
use of Pulse’s own W9908/W9909 C-clips. Mounting the antenna is
easily accomplished using the thin but aggressive holding adhesive
backing. It is recommended for mounting on the inside of plastics
covers or carriers embedded in the device.
