Contactless payment card reader with a frusto-conical operating volume |
摘要 |
A contactless payment card reader has a frusto-conical operating volume. The frusto-conical shaped operating volume has defined magnetic field strengths for powering and communicating with proximity payment cards. The reader can serve as a reference reader, which is representative of product readers deployed in contactless payment card systems, to test product contactless payment cards under conditions that simulate field use of the cards.
