The first commercial DRAM IC chip was the Intel 1103, which was manufactured on an 8 μm MOS process with a capacity of 1 kbit, and was released in 1970. [9] [21] [22] Synchronous dynamic random-access memory (SDRAM) was developed by Samsung Electronics. The first commercial SDRAM chip was the Samsung KM48SL2000, which had a capacity of 16 Mbit ...
A smart card ( SC ), chip card, or integrated circuit card ( ICC or IC card ), is a card used to control access to a resource. It is typically a plastic credit card-sized card with an embedded integrated circuit (IC) chip. [ 1] Many smart cards include a pattern of metal contacts to electrically connect to the internal chip.
A point of sale card terminal. Point-of-sale malware (POS malware) is usually a type of malicious software that is used by cybercriminals to target point of sale (POS) and payment terminals with the intent to obtain credit card and debit card information, a card's track 1 or track 2 data and even the CVV code, by various man-in-the-middle attacks, that is the interception of the processing at ...

v. t. e. In computing, magnetic-core memory is a form of random-access memory. It predominated for roughly 20 years between 1955 and 1975, and is often just called core memory, or, informally, core . Core memory uses toroids (rings) of a hard magnetic material (usually a semi-hard ferrite ). Each core stores one bit of information.
Dynamic random-access memory ( dynamic RAM or DRAM) is a type of random-access semiconductor memory that stores each bit of data in a memory cell, usually consisting of a tiny capacitor and a transistor, both typically based on metal–oxide–semiconductor (MOS) technology. While most DRAM memory cell designs use a capacitor and transistor ...
These paper slips had to be taken to the bank for processing. This was a cumbersome and time-consuming process. Point of sale terminals emerged in 1979, when Visa introduced a bulky electronic data capturing terminal which was the first payment terminal. In the same year magnetic stripes were added to credit cards for the first time. This ...
A memory card is an electronic data storage device used for storing digital information, typically using flash memory. These are commonly used in digital portable electronic devices, such as digital cameras as well as in many early games consoles such as the Nintendo Wii. They allow adding memory to such devices using a card in a socket instead ...
