The answer is NO. Different hotels may use different chips or magnetic stripes even if they are using the same locking system. So, we would need 2 types of sample cards for testing; 1. One that hotel is already used; 2. One that hotel never used. 2 pcs each would be the best. Once we’ve tested the cards, we will get to know what kind of magstripe or RFID chip we need to use for the key card. Don’t you worry if you don’t have any cards in your hand, contact us for a sample pack to test in the hotel. Normally, we provide preprinted cards with magnetic stripe or RFID chip only without encoding. The hotel will encode each hotel card with an encoder, only an encoded key card could open the right door. Hotels change their key card frequently in order to maintain their image branding, which also pushes the cost higher – especially when the chip they are using happens to be an expensive one.
