AAAS adheres to PCI (Payment Card Industry) compliance protocols that encrypt and keep safe your credit card information. The PCI Security Standards Council is constantly looking for weaknesses in the protocols and announced changes to keep hackers from taking advantage of vulnerabilities in older web browsers.
Beginning on September 9, 2017, those attempting to complete a credit card transaction with AAAS or its publication Science who are using a browser that does not support the new PCI encryption technology (TLS 1.1 or TLS 1.2), may receive a "Server Unreachable" message and the transaction will be terminated. To avoid this inconvenience, we strongly encourage you to update your browser on a regular basis to the latest version available.
Thank you for your continued support of AAAS/Science!
