can you read 2 rfid tags next to each other The orientation of the RFID tag can also affect the ability to read multiple tags simultaneously. In some cases, tags may be placed in such a way that they interfere with each other, making it difficult for the reader to detect each tag. Yes. Though not a phone, but a pseudo phone device, absolutely. This is an attack where one phone is near a contactless card and it transmits the card information to a second phone .

How Many Tags Can Be Read By an RFID Reader at One Time?
The orientation of the RFID tag can also affect the ability to read multiple tags simultaneously. In some cases, tags may be placed in such a way that they interfere with each other, making it difficult for the reader to detect each tag. Technically, all RFID readers can interrogate only one tag at a time. If two tags are sending signals to a reader simultaneously, there is no way for the device to distinguish one . The orientation of the RFID tag can also affect the ability to read multiple tags simultaneously. In some cases, tags may be placed in such a way that they interfere with each other, making it difficult for the reader to detect each tag.
Technically, all RFID readers can interrogate only one tag at a time. If two tags are sending signals to a reader simultaneously, there is no way for the device to distinguish one from another. However, there are special anti-collision algorithms that enable interrogators to “singulate” on specific tags—that is, a reader can talk to one .
If two tags are placed with one behind the other, the tag in front can block the signal of the one in back of it. If no energy reaches the tag behind, it can not be read. With high-frequency (HF) tags, a company called Magellan Technology has solved this issue using phased jitter modulation (PJM).
Can RFID Readers Read Multiple Tags? Absolutely, yes! One of the best features of switching to RFID Fixed Asset tracking is that you can read dozens of tags per second. Compared to barcode handheld readers, RFID handheld readers can eliminate the need to scan each individual asset for your inventory.A common query that surfaces is whether RFID readers can effectively read multiple passive tags at once. Let’s delve into this inquiry to grasp the full scope of RFID technology’s capabilities and advantages across industries. If you have multiple objects or at least are not just gluing all 20 tags to make a single meta-tag, you'll be fine. Here are some example reader modules from digikey: http://www.digikey.com/product-search/en/rf-if-and-rfid/rfid-reader-modules/3539638?k=thingmagic.
If it's just two tags you could sandwich foil between them and use them one at a time directionally. Or build your implementation to have two antennas facing each other in combination with the RFID sandwich.
When you put them next to each other, they become like a transformer and pass power one way and data the other. Powering up two tags at once will create a chaotic response that the reader won't know how to interpret. RFID readers may make use of anti-collision algorithms to enable a single reader to read more than one tag in the reader's field". This is taken from here. Generally 900 MHz is the preferred choice when it comes to high read rate.
