Two-part Contactless Reader for Aperture-Free Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing contactless payment card readers face installation challenges in environments exposed to the elements or where drilling through surfaces is inconvenient, such as outdoor or wet locations, due to their requirement for aperture-based connections and susceptibility to damage.
Innovation Solution
A two-part contactless card reader system with a customer-facing unit and a base unit installed on opposite sides of a counter without a physical aperture, using inductive coupling for data and power transmission, and a waterproof customer-facing unit for exposure to elements, allowing installation in various environments without altering the counter's surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a contactless reader is installed with aperture-based connections, then data and power transmission can be achieved, but the counter surface must be altered and the system becomes vulnerable to environmental damage
Solution Approach 1:
The contactless reader is divided into two separate parts: a base unit that attaches to the counter surface and a customer-facing unit that hangs from the counter. This segmentation eliminates the need to drill apertures through the counter while maintaining functional connectivity between the two parts via magnetic coupling.
Solution Approach 2:
The patent replaces mechanical aperture-based connections with magnetic coupling between the base unit and customer-facing unit. This substitution allows data and power transmission without physical penetration of the counter surface, preserving structural integrity and enabling easier installation.
2Adaptability or versatility
If the reader is exposed to outdoor environments, then versatility is improved, but the reader becomes susceptible to damage from elements
Solution Approach 1:
The customer-facing unit is designed with a waterproof housing that provides environmental protection specifically where needed (at the customer interaction point), while allowing the base unit to remain separately mounted on the counter. This localized protection enables outdoor deployment without compromising the reader's functionality.
3Strength
If drilling through the counter is required for installation, then secure mounting is achieved, but the counter's structural integrity is compromised and installation becomes costly
Solution Approach 1:
By separating the reader into a base unit and customer-facing unit, the system can mount the base unit to the counter surface without drilling through it. The magnetic coupling between units provides secure mounting while preserving the counter's structural integrity.
Solution Approach 2:
The patent replaces drilling and mechanical penetration of the counter with magnetic attachment. The base unit attaches to the counter surface magnetically, eliminating the need to compromise the counter's structure while maintaining secure mounting for the reader system.

Function Achieved in This Case
Enables contactless payment transactions in diverse environments, including outdoor and wet locations, without compromising the counter's integrity or requiring drilling, ensuring operational reliability and aesthetic appeal.
Implementation Method 1
using inductive coupling for data and power transmission
Implementation Method 2
a radio frequency identification (RFID) integrated circuit (IC, often referred to as a 'chip') is embedded in the card body. A suitable antenna is also embedded in the card body and is connected to the RFID chip to allow the chip to receive and transmit data by RF communication via the antenna.

AI summary
Pursuant to some embodiments, systems, methods, apparatus and means for operating two-part contactless card readers are provided. In some embodiments, the two-part contactless card reader is installed in association with a transaction counter, where the transaction counter has a first surface and a second surface. Pursuant to some embodiments, the device includes a customer-facing unit installed on a first surface of the transaction counter, a base unit installed on a second surface of the transaction counter, the second surface apart from the first surface, where the first surface and the second surface are separated by a substantially solid material with no aperture formed therethrough. The base unit includes electronic components for generating interrogation signals for interrogating contactless cards, the electronic components also for receiving card data signals from the contactless cards, the card data signals indicative of card data stored in the contactless cards. The customer-facing unit includes at least one indicia for indicating, to a user of a contactless card, a location at which the contactless card is to be presented to the contactless card reader.
