For example, a single smart card could allow a user to reach certain floors via the elevator, gain access to restricted rooms, open the gate to the parking lot and more. Because the internal clock rate of microcontrollers are 3 to 5 MHz, there is a need to add a component, accelerator for the cryptographic functions.
Contact smart cards are mainly used in electronic security whereas contactless cards are used in transportation and/or door locks. You need that key to identify yourself in the network and be able to enjoy the service. Smart Card This type of smart cards, contains EEPROM(Electrically Erasable Programmable Read-Only Memory), non-volatile memory.
All depends on many aspects, like size, use, and range of action. Vcc : Power supply input (optional use by the card). The readers for contactless smart cards may or may not have a slot. Some smart cards have golden plates, contact pads, at one corner of the card. These chips come complete with internal controllers, storage units, sequential logic circuits, arithmetic units and operating system. The data can be locked with a PIN (Personal Identification Number), your password.
The dual SIM card phones have three types. The SIM Cards come in different versions.
A combo card has a contact pad for the transaction of large data, like PKI credentials, and a wire loop for mutual authentication.

The readers of smart cards usually connected to the computer via USB or serial port. This is very practical if you are traveling because you can avoid international roaming which can be very expensive.
In this sense, the SIM card is a mini-computer that functions inside another device like a mobile phone, tablet or PC.
Now we get crazy if a text is not answered in seconds. Read more about the Difference between CDMA and GSM. It is a small piece of extra plastic that stores the subscriber service key safely. Smart cards are “smart” because they have embedded chips that can store and process data.
However, when you use a phone with GSM technology, you can easily remove the SIM Card and later insert it into another device.
They also have embedded readers for GSM style mini smart cards. When you insert the card into the reader, the contacts in the reader sit on the plates. Nevertheless, if you need a Postpaid SIM Card plan, you can contact the local internet service providers in your country and choose a SIM card plan which works for you. or in combination with an internal reset control circuit (optional use
A variant of CompactFlash, this memory card … Because it is non-volatile when you remove the card from the reader, power is cut off, card stores the data.
As smart cards have embedded microprocessors, they need energy to function and some mechanism to communicate, receiving and sending the data. This type of smart cards are called Contact Smart Cards… Nowadays the mobile phone manufacturers are using smaller SIM cards to save space and make the smartphone or device lighter.
On the contrary, the device has an ESN (electronic serial number) so you cannot change your phone. You do not have to be in a rush to choose your communication tools.
In brief, even when SIM cards seem to be the same, they all are different.
Summary Both are radio systems used on cell phones.
