Essential Applications of Smart Cards for IoT Technology


The Internet of Things (IoT) is a hot topic. The IoT is a vital issue for anyone working with technology or developing their business with the help of technology. The IoT promises much, but it is also linked with security concerns and potential problems. Smart cards are set to provide better security for IoT devices, which could see the IoT rolled out to many more applications in the future.

What is the IoT?

The Internet of Things encompasses electronic devices and applications that provide integration between the “real” world and the world of technology. IoT devices include wearable technology designed to make life easier, as well as applications in logistics, construction, and agriculture. IoT technology powers smart homes and smart vehicles. It is set to explode in popularity in the coming years.

However, concern has been levied regarding these devices in terms of security. IoT devices are considered less secure since they are connected over networks. These networks are vulnerable to hackers, attacks, and unauthorised access. The question remains, as IoT devices become more popular, as to how to make them more secure.

Smart Cards are Secure

Consumers recognise the use of smart cards to protect them and make tasks easier in areas such as online banking, payments, and building access. You can make secure payments online and in stores with smart card technology. Smart cards also provide safer access to business and residential premises. Smart cards are protected as they are encrypted, and the data on smart cards is not easily accessed by unauthorised people. Smart card technology is also combined with a two-factor identification system such as passwords or PINs to enhance access or purchase security.

Smart Cards Increase IoT Security

IoT technology is more secure when it uses hardware with embedded security features. Encryption and security components can be built into the device as it is manufactured. For example, embedded features like smart chips can enhance privacy and improve security. Smart chips are also found in smart cards; therefore, the technology is highly suited to IoT devices.

Smart cards can also be used alongside IoT devices to provide robust identification features. For example, intelligent systems that control functions in a house such as door entry, heating, lighting, and entertainment may only be accessed through smart card login, combined with additional security such as a PIN or password. This means access is only given to authorised people. Smart cards can also be used to log into IoT servers in the workplace. The login would generate a unique session key that would provide access for a limited period in order to protect the system. Smart cards also ensure that any information transmitted over the IoT networks is encrypted and therefore secure.

Using Smart Cards with IoT

It is important to integrate smart card technology into IoT technology at the manufacturing stage, which is where manufacturers can embed microchips into devices to connect with smart card readers and cards. A smart card system with cards, an ID card printer, and IoT devices is easy to manage and simple to replicate as a system grows.
