These chip offer better protection, this chip includes an intelligent 256-Byte EEPROM with Write Protect Function and Programmable Security Code (PSC). HICO MAGNETIC STRIP / 2 tracks, 2750oe ,The more stronger and more wide magnetic field makes our cards more durable, ensure the blank credit cards will last a long time. WORKS WITH ALL STANDARD PRINTERS: These chip cards work well with all basic ID card printers and standard ID card printers, including DC150i and Fargo HDP5000 Zebra P330i. Not for use with inkjet printers. Product Description: These SLE4442 EMV Chip, Magnetic Stripe cards are ideal for storing information that can be accessed by being inserted or swiped. These cards are perfect for use as credit cards, gift cards & photo ID cards. The sle4442 blank cards are waterproof/weatherproof and are 2mm thick. The blank chip cards have the option of being any of the following: credit/debit, gift, photo ID cards. IC Cards (Integrated Circuit Card) are also called Smart Cards similar to Java blank cards. These blank cards with chip are Intelligent Cards, Microcircuit Cards, or IC Chip Cards. A microcircuit chip is embedded in the card that complies with ISO 7816 standards. The chip is embedded with 256bits of memory.The blank credit cards will work with thermal printers. The SLE-4442 Secure Memory Chip 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 256 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 . By means of a three digit PIN the memory can be protected against alternation of the data. The information contained in the chip (except the PIN) can always be read.The first 32 Bytes can be protected irreversibly.
