Typical applications: enterprise / Campus All-in-one Card, bus stored value card, highway toll collection, parking lot, community management, etcThe chip fully compatible with Philips S70 card is gt23sc4469. The performance, purpose and use method of gt23sc4469 chip are exactly the same as Philips S70 card. However, as Philips S70 card 4K is an original imported chip, there will be many additional charges such as taxes, so the price is relatively high. GT23SC4469 is produced in Chinese mainland, with lower production cost and stronger price competitiveness. Therefore, in more and more systems, GT23SC4469 chips are used instead of PHILPS S70 cards.
