Cash register with credit card

A large number of the SAM4s cash registers have the abilty to interface with credit card. Any of the SAM4s registers require a Datacap Twin Tran or similar model as do most of the Sharp cash registers. The models that interface are

• SAM4s ER-285M
• SAM4s ER-380M
• SAM4s ER-390M
• SAM4s ER-650
• SAM4s ER-650R
• SAM4s SPS-320
• SAM4s SPS-340
• SAM4s SPS-345
• SAM4s SPS-520R
• SAM4s SPS-520F
• SAM4s SPS-530R
• SAM4s SPS-530F
• SAM4s ER-920
• SAM4s ER-925
• SAM4s ER-940
• SAM4s ER-945
• SAM4s ER-5200M
• SAM4s ER-5215M
• SAM4s ER-5240M
• SAM4s SPS-2000

I may have left out a few of them. They by far have more than anyone else.
