We have a AT870 UHF RFID Reader. Here is a link. [url removed, login to view] It is Windows CE based. The software on the handheld reader we are using to read the RFID tags is ATUHF_net. The software we are using to write to the tag is Tag writer/reader 1.1 on a laptop. Here are our issues with both software packages. The ATUHF_net shows all the digits on the tag. There are 24 characters on the RFID tag. Even when we write our number on the take (which is P100 through P99999 there are leading zeros). We need to eliminate any leading characters so the reader only shows P100. The problem we have with the writing software is that is does not allow for the “P”. It only writes numbers. We are looking for someone to write us 2 programs (or modify our existing) to resolve these issues. Feel free to e-mail me with any questions.
