A comparison between SMART and V5 technologies for coin recognition

In this blog post, we will explore the differences between two coin recognition technologies developed by CTcoin: SMART and V5. Both technologies are based on electromagnetic sensors (EMS), but they have distinct design choices and capabilities. Understanding these differences is essential for making informed decisions about future projects involving SMART coin counting technology.

SMART vs. V5 coin recognition technologies

Sensor Design: The V5 sensor is an analog sensor, while the SMART incorporates an on-board computer within the sensor itself, making it the first digital sensor in the market. This design choice gives SMART technology a significant advantage in reducing sensitivity to electromagnetic noise and enables the collection of higher quality and more extensive data.

Coil Configuration: The SMART sensor operates with three coils, whereas the V5 utilizes only two coils (one for sending and one for receiving). This difference in coil configuration results in six distinct sensor designs for the V5, while the SMART sensor can accommodate all requirements in “one sensor fits all,” offering cost-effective solutions for OEM applications.

Platform and Protocol: The V5 technology was designed on an embedded platform with functionalities inherited from the CTcoin CDS and tabletop products. On the other hand, the SMART concept is a counting (sorting) unit that relies on the OEM’s control and application software, following the industry-standard CCtalk protocol, while the V5 protocol is proprietary.

Advantages of SMART Technology

Superior Accuracy and Performance: SMART technology offers precise coin recognition capabilities, successfully identifying all currencies and denominations tested so far, outperforming the V5 technology.

Cost-Effectiveness: SMART technology presents a cost advantage as V5 components become increasingly expensive due to their lifecycle. Moreover, the SMART electronics and software can compensate for many of the mechanical differences required to handle specific currencies, making it a more cost-effective option for OEMs.

Seamless Integration: CTcoin has invested considerable resources in developing the SMARTsuite, a comprehensive software platform and tool that facilitates seamless integration and business transactions with CTcoin. The SMARTsuite offers user-friendly tools that set it apart from competing products.

Future Transition to SMART Technology

In July 2023, CTcoin has a guaranteed supply of approximately 5,000 V5 sensors and controllers, which will cover projected consumption for the next two years. However, the company acknowledges the eventual transition away from V5 technology.

As SMART technology continues to develop and demonstrate its capabilities, discussions with current V5 customers can be initiated. The goal is to provide compelling reasons for customers to switch to SMART when it becomes compelling to them.


CTcoin’s SMART technology represents a significant step forward in the field of coin recognition. With its superior accuracy, cost-effectiveness, and stable performance, SMART positions CTcoin as the leading supplier of coin counting and sorting technology.

CTcoin has secured its present customer base by procuring a significant quantity of the reliable yet obsolete V5 sensors and electronics, ensuring a stable supply until the end of 2024.

As CTcoin continues to invest in SMART development and collaboration with industry partners, the technology’s capabilities will continue to grow, solidifying its position in the market.

SMART’s innovative design and functionalities make it an attractive option for OEMs and a crucial asset in CTcoin’s journey toward becoming a preferred supplier in the cash handling industry.
