Radio frequency identification (RFID) devices are typically used as proximity or smartcard identification in tracking and access control systems. These systems operate on the assumption the token is in close proximity to the reader because of the communication channel’s physical limitations.
Historically, liquid fluoropolymer coatings have been the product of choice for coating aluminum architectural components in Canada. This is due to the extensive colour and gloss options, and their ability to be economically produced in small batches of custom hues.

For the past 100 years, developers and architects driven by the Modern movement have designed skeletal boxes skinned with glass for beauty and simplicity. Natural light, the diminishing of separation between interior and exterior, and open working environments were the result of these experimental glazing assemblies. This strategy continues to spread throughout the globe, in all climates.
