This leading global life sciences and health care diagnostics company is based in Burlington, North Carolina. It is an S&P 500 business with annual revenues of US$10 billion, operating one of the largest clinical laboratory networks in the US with a network of 36 primary laboratories.

The company provides diagnostic, drug development and technology-enabled solutions for more than 115 million patient encounters per year, processing tests on more than 2.5 million patient specimens per week. They also support clinical trial activity in approximately 100 countries through its industry-leading central laboratory business, generating more safety and efficacy data to support drug approvals than any other company.


The business has direct contact with its customers who need to make payments for tests, drugs or insurance products and services. They provide contact center agent-assisted payments which means that they handle payment card data. In turn, this requires that heir contact center stores, transmits and processes payment card data so they are required to comply with the Payment Card Industry Data Security Standard (PCI DSS) in order to continue to be able to take such payments.

It is imperative for their customer service reps (CSRs) to be able to stay in touch with their callers throughout the transaction which adds a further complication into the handling of data, especially in an industry where call recording is also required. 


Eckoh delivered its CallGuard solution – using patented audio tokenization to mask the sensitive payment card data from the agent so that they see, hear and record nothing.

When a caller keys in their card details using their phone’s keypad, audio tones are generated (known as DTMF digits) which match the card number. CallGuard replaces these numbers immediately with replacement numbers – tokens - which are automatically inputted to the agent’s payment page. Since the tokenized data is not real card information it can be stored, transmitted and processed safely and compliantly.  Once the payment is ready to submit to the Payment Service Provider (PSP), CallGuard converts the tokenized data back into the real card number before forwarding to the PSP.

We’re excited to implement Eckoh’s CallGuard Audio Tokenization because we believe it enhances our ongoing commitment to the privacy and security of our customers and it’s good for our business and customer experience. Global Life Sciences Business – USA
