Why did BCA Smart need an Advanced Electronic Signature solution?

BCA Smart had extensive experience with QES but needed a technology partner to provide AES capabilities for a new digital signature platform.

Founded in 2006, BCA had established itself as a leader in smart card technology and a key player in the French digital identity ecosystem. The company had developed a platform designed to help small businesses process quotes, orders, invoices, contracts, and other documents through email and smartphones.

The platform needed to support both AES and QES. BCA had expertise in QES but identified AES as a newer area that it wanted to provide through a specialist partner.

The challenge was finding a provider with the appropriate technology, commercial terms, certifications, and cultural fit.

The Conclusion

How did BCA Smart integrate Nitro Sign into its digital signature platform?

BCA identified Nitro as an AES partner at the beginning of its platform development process in 2018.

BCA selected Nitro based on its technology, certifications, experience with advanced electronic signatures, and relationship with the Nitro team. Nitro's current documentation confirms support for Advanced and Qualified Electronic Signatures, including eIDAS and ZertES requirements through Nitro Sign Enterprise.

BCA and Nitro then worked together to refine the technical integration over several years. The resulting platform was designed to combine BCA's QES capabilities with Nitro's AES capabilities in a single digital signature experience.
