Protect your credit cards and RFID cards


Recent News reports have demonstrated how easy it is for someone to steal information off your credit cards without your knowledge.<br /> Today almost everyone has at least 1 card in his or her wallet which contains an Radio Frequency Identification Device (RFID),just a fancy name for a chip embedded in the card. While these can and do benefit us in many ways, unscrupulous persons have the capability of reading the information on the card while it's still in you purse or pocket. The stolen information might include your credit card numbers as well as other personal information that in the wrong hands might proof disastrous to you. You can protect this unwanted intrusion by paying for expensive wallets or purses that protect your information by blocking the signal from the RFID chip the RFID reader OR you can protect your information now for almost $0. <br /> <b><u>Heres' how:</u></b><br /> <br /> <u>A 27 microns thick piece of aluminum foil is adequate to block an RFID signal and your standard household foil (Reynold Wrap) is 1143 microns thick. That's 42.3 times thicker than you need to stop the signal.</u><br /> <u>Cut a few strips of foil to fit along the inner lining of your wallet, purse or whatever your credit cards are in and your protected. Simple, cheap and effective protection.</u><br />

Do credit cards have RFID chips? Can I protect my credit cards RFID chips from getting stolen?


There are some credit cards that have RFID chips in them, they are only in the tap and pay cards like paypass or expresspay cards. You can buy a sleeve or an RFID wallet that will protect your card.

Fatal error 231 on oki c5800 after changing toner, tried power off/on still doesn't work


From the service manual, doesn't look good.
A technicain will have to look at the printer.

RFID Reader I/F Error
An interface error was detected with the RFID reader device.
01 : communication error between the RFID reader and the engine PCB.
02 : the transceiver circuit error of the RFID reader.
03 : communication error between the RFID reader and the Tag chip.
04 : the RFID Tag detection error (more than 4 chips).
If rebooting the machine does not improve the symptom, you need to
check the device.

SP55 Datacard


Hello,
The printer does not know the the model of the ribbon installed and thinks it is a monochrome (single color) Print ribbon. You can verify this in the Driver toolbox under the supply tab, or in the advanced printing options.
The Datacard SP series printers use an RFID Radio freq. tag in the take up spool end of the ribbon. This identify s the ribbon model and supply use settings for the printer.
Make sure you have the most recent driver and firmware from Datacard, There is a firmware Update Available to help reading "weak" RFID tag's
Next try removing the RFID tag from another (old) ribbon and see if it that fixes the problem)
Aside from that you:
May have a counterfeit (non-Datacard) ribbon
A bad RFID tag
Someone removed your RFID tag
You need a firmware update (weak RFID tag)
A bad RFID reviver in the printer, which is a fairly cheap repair.
Basically try a new print ribbon if that does not correct the issue, have the printer serviced.
