Magnetic Stripe Card Magnetic Stripe Card Any type of card that contains data embedded in a strip composed of iron particles in plastic film. The front of the card contains identifying information, such as the cardholder’s name and the issuing company’s name, while the magnetic stripe resides on the back. These cards are usually a little larger than 2 inches by 3 inches and made of plastic or durable paper. Types of magnetic stripe cards include driver’s licenses, credit cards, employee ID cards, gift cards and public transit cards. BREAKING DOWN 'Magnetic Stripe Card’ When a magnetic stripe card is swiped through a magnetic stripe reader, the reader decodes the data in the magnetic stripe to enable a transaction to go through. The transaction might allow an employee to access a building or a customer to pay a merchant by credit card. If the magnetic stripe becomes dirty, scratched or demagnetized, the card may not work. The magnetic stripe on a credit card

SLE4442 CONTACT CHIP SMART CARD SLE4442 Smart Card The SLE-4442 Secure Memory Card is one of the most popular “Smart Memory Cards” in the world. This chip includes an intelligent 256-Byte EEPROM with Write Protect Function and Programmable Security Code (PSC). This chip contains and EEPROM organized 1024 x 8 bit offering the possibility of programmable write protection for each byte. Reading of the whole memory is always possible. The memory can be written and erased byte by byte . We supply blank SLE4442 cards and SLE4442 pre-printed card. Description : – Synchronous communication protocol, ISO 7816 compatible – EEPROM size is 256 bytes split into the following areas: 26 bytes for card manufacturer data 2 bytes for card issuer reference 4 bytes for card identification data 224 bytes for main user data – Access to the memory is protected by a 3 byte secret code for data write only – Free Read of Data (except PIN) – Answer to reset according to ISO 7816/3 standard – Data

Mini SIM : This SIM card has been around for many years now and can be found on older smartphones or certain feature phones even today. The size of the SIM card is pretty big and if phones like the iPhone 3GS and Nexus 4 are some examples of the phones that relied on the mini SIM card. Micro SIM : The micro SIM is pretty much the standard these days for the majority of smartphones. Pretty much all Android smartphones at the moment accept the micro SIM as the SIM card of choice. It is noticeably smaller than the mini SIM and has helped to contribute to the creation of thinner smartphones. Phones such as the iPhone 4iPhone 4S Nexus 5 andSamsung Galaxy S5are examples of phones that use the micro SIM. Nano SIM : The nano SIM is currently the smallest SIM card available at the moment. At one point in time there was a bit of contention between Apple and Nokia regarding the nano SIM in which Apple was looking to make the nano SIM the new standard in SIM cards. The nano SIM is m
